GPIO Library
|
||||
============
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
The XMOS GPIO library allows you to access xCORE ports as low-speed GPIO.
|
||||
|
||||
Although xCORE ports can be directly accessed via the xC programming
|
||||
language this library allows more flexible usage. In particular, it
|
||||
allows splitting a multi-pin output/input port to be able to use
|
||||
the individual pins independently. It also allows accessing ports
|
||||
across separate XMOS tiles or separate XMOS chips.
|
||||
|
||||
Features
|
||||
........
|
||||
|
||||
* Abstract interface to GPIO functionality of XMOS ports
|
||||
* Allow control of individual bits of multi-bit ports
|
||||
* Allow access to ports across tiles
|
||||
|
||||
Operating modes
|
||||
...............
|
||||
|
||||
* Multi-bit output for individual access to the pins of a multi-bit output port
|
||||
* Multi-bit input for individual access to the pins of a multi-bit input port
|
||||
* Multi-bit input for individual access to the pins of a multi-bit
|
||||
input port allowing the application to react to events on those pins
|
||||
|
||||
Software version and dependencies
|
||||
.................................
|
||||
|
||||
The CHANGELOG contains information about the current and previous versions.
|
||||
For a list of direct dependencies, look for DEPENDENT_MODULES in lib_gpio/module_build_info.
|
||||

||||

||||
(b) you must include a copy of this Licence with every copy of the Software and documentation you publish, distribute and make available and you may not offer or impose any terms on such Software that alter or restrict this Licence or the intent of such Licence, except as permitted below (Additional Terms).
|
||||
|
||||
The licence above does not include any Compiled Code which XMOS may make available under a separate support and licence agreement.
|
||||
|
||||
2.2 **Derivatives.** You may create and modify Derivatives and use, copy, display, publish, distribute and make available Derivatives:
|
||||
|
||||
2.2.1 for personal or academic, non-commercial purposes; or

|
||||
Any rights, including all intellectual property rights and all trademarks not expressly granted herein are reserved in full by the authors or copyright holders.

|
||||
Subject to the licences granted under this Licence any Contributor retains all rights, title and interest in and to any Derivatives made by Contributor subject to the underlying rights of XMOS in the Software. XMOS shall retain all rights, title and interest in the Software and any Derivatives made by XMOS (“XMOS Derivatives”). XMOS Derivatives will not automatically be subject to this Licence and XMOS shall be entitled to licence such rights on any terms (without obligation) as it sees fit.
|
||||
|
||||

Connecting external signals to multi-bit ports
|
||||
----------------------------------------------
|
||||
|
||||
Multi-bit ports can be connected to independent signals in either an
|
||||
all output configuration (see :ref:`lib_gpio_n_bit_output`) or an all
|
||||
input configuration (see :ref:`lib_gpio_n_bit_input`). This implies
|
||||
two important restrictions:
|
||||
|
||||
* **Bi-directional signals cannot use this library**
|
||||
* **The signals on the same port must go in the same direction**
|
||||
|
||||
To use bi-directional signals, a dedicated 1-bit hardware port needs
|
||||
to be used.

Performance restrictions
|
||||
........................
|
||||
|
||||
This library allows independent access to the pins of mulit-bit ports
|
||||
by multiplexing the port output or input in software. This means that
|
||||
there are some performance implications, namely:
|
||||
|
||||
* The internal buffering, serializing and de-serializing features of
|
||||
the xCORE port are not available.
|
||||
* The software locking and multiplexing between individual bits of
|
||||
the port limits performance. As such, toggling
|
||||
pins at speed above 1Mhz, for example, is not achievable (on a
|
||||
62.5Mhz logical core). The limit may be lower depending on the other
|
||||
code is running on the core and how the other pins of the port are being
|
||||
driven.
|
||||
|
||||
As such, sharing multi-bit ports is most suitable for slow I/O such as
|
||||
LEDs, buttons and reset lines.

Usage

-----
|
||||
|
||||
Output GPIO usage
|
||||
.................
|
||||
|
||||
Output GPIO components are instantiated as parallel tasks that run in a
|
||||
``par`` statement. These components connect to the hardware ports of
|
||||
the xCORE device. The application
|
||||
can connect via an interface connection using an array of the ``output_gpio_if``
|
||||
interface type:
|
||||
|
||||
.. figure:: images/output_gpio_task_diag.*
|
||||
|
||||
Output GPIO task diagram
|
||||
|
||||
For example, the following code instantiates an output GPIO component
|
||||
for the first 3 pins of a port and connects to it::
|
||||
|
||||
port p = XS1_PORT_4C;
|
||||
|
||||
int main(void) {
|
||||
output_gpio_if i_gpio[3];
|
||||
par {
|
||||
output_gpio(i_gpio, 3, p, null);
|
||||
task1(i_gpio[0], i_gpio[1]);
|
||||
task2(i_gpio[2]);
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
Note that the connection is an array of interfaces, so several tasks
|
||||
can connect to the same component instance, each controlling
|
||||
different pins of the port.
|
||||
|
||||
The application can use the client end of the interface connection to
|
||||
perform GPIO operations e.g.::
|
||||
|
||||
void task1(client output_gpio_if gpio1, client output_gpio_if gpio2)
|
||||
{
|
||||
...
|
||||
gpio1.output(1);
|
||||
gpio2.output(0);
|
||||
delay_milliseconds(200);
|
||||
gpio1.output(0);
|
||||
gpio2.output(1);
|
||||
...
|
||||
}
|
||||
|
||||
More information on interfaces and tasks can be be found in
|
||||
the :ref:`XMOS Programming Guide<programming_guide>`. By default the
|
||||
output GPIO component does not use any logical cores of its
|
||||
own. It is a *distributed* task which means it will perform its
|
||||
function on the logical core of the application task connected to
|
||||
it (provided the application task is on the same tile).
|
||||
|
||||
Input GPIO usage
|
||||
................
|
||||
|
||||
There are two types of input GPIO component: those that support events
|
||||
and those that do not support events. In both cases,
|
||||
input GPIO components are instantiated as parallel tasks that run in a
|
||||
``par`` statement. These components connect to the hardware ports of
|
||||
the xCORE device. The application
|
||||
can connect via an interface connection using an array of the ``input_gpio_if``
|
||||
interface type:
|
||||
|
||||
.. figure:: images/input_gpio_task_diag.*
|
||||
|
||||
Input GPIO task diagram
|
||||
|
||||
For example, the following code instantiates an input GPIO component
|
||||
for the first 3 pins of a port and connects to it::
|
||||
|
||||
port p = XS1_PORT_4C;
|
||||
|
||||
int main(void) {
|
||||
input_gpio_if i_gpio[3];
|
||||
par {
|
||||
input_gpio(i_gpio, 3, p, null);
|
||||
task1(i_gpio[0], i_gpio[1]);
|
||||
task2(i_gpio[2]);
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
Note that the connection is an array of interfaces, so several tasks
|
||||
can connect to the same component instance, each controlling
|
||||
different pins of the port.
|
||||
|
||||
|newpage|
|
||||
|
||||
The application can use the client end of the interface connection to
|
||||
perform GPIO operations e.g.::
|
||||
|
||||
void task1(client input_gpio_if gpio1, client input_gpio_if gpio2)
|
||||
{
|
||||
...
|
||||
val1 = gpio1.input();
|
||||
val2 = gpio2.input();
|
||||
...
|
||||
...
|
||||
val1 = gpio1.input();
|
||||
val2 = gpio2.input();
|
||||
...
|
||||
}
|
||||
|
||||
More information on interfaces and tasks can be be found in
|
||||
the :ref:`XMOS Programming Guide<programming_guide>`. By default the
|
||||
output GPIO component does not use any logical cores of its
|
||||
own. It is a *distributed* task which means it will perform its
|
||||
function on the logical core of the application task connected to
|
||||
it (provided the application task is on the same tile).
|
||||
|
||||
Using events
|
||||
............
|
||||
|
||||
The :c:func:`input_gpio_with_events` and
|
||||
:c:func:`input_gpio_1bit_with_events` functions support the event
|
||||
based functions of the input GPIO interface::
|
||||
|
||||
port p = XS1_PORT_4C;
|
||||
|
||||
int main(void) {
|
||||
input_gpio_if i_gpio[3];
|
||||
par {
|
||||
input_gpio_with_events(i_gpio, 3, p, null);
|
||||
task1(i_gpio[0], i_gpio[1]);
|
||||
task2(i_gpio[2]);
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
In this case the application can request an event on a pin change and
|
||||
then select on the event happening e.g.::
|
||||
|
||||
gpio.event_when_pins_eq(1);
|
||||
select {
|
||||
case gpio.event():
|
||||
// This event was caused by the pin value being 1
|
||||
...
|
||||
break;
|
||||
}
|
||||
|
||||
|newpage|
|
||||
|
||||
Pin maps
|
||||
........
|
||||
|
||||
The GPIO tasks all take a ``pin_map`` argument. If this is ``null``
|
||||
then the elements of the inteface array will correspond with the a bit
|
||||
of the port based on the array element index. So the first element of
|
||||
the array will control bit 0, the second with control bit 1 and so on.
|
||||
|
||||
Alternatively an array can be provided mapping array elements to
|
||||
pins. For example, the following will map the array indices to pins 3,
|
||||
2 and 7 of the port::
|
||||
|
||||
char pin_map[3] = {3, 2, 7};
|
||||
|
||||
int main() {
|
||||
...
|
||||
par {
|
||||
output_gpio(i_gpio, 3, p, pin_map);
|
||||
...
|
||||
|
||||
Output GPIO API
|
||||
---------------
|
||||
|
||||
All GPIO functions can be accessed via the ``gpio.h`` header::
|
||||
|
||||
#include <gpio.h>
|
||||
|
||||
You will also have to add ``lib_gpio`` to the
|
||||
``USED_MODULES`` field of your application Makefile.

|
||||
-----
|
||||
|
||||
* ADDED: VPU enabled ASRC and SSRC providing a 2x speed improvement
|
||||
* ADDED: Asynchronous FIFO with phase detector and PID rate controller for
|
||||
ASRC usage
|
||||
* ADDED: Support for XCommon CMake build system
|
||||
* FIXED: Function pointer annotation avoid stack corruption when using
|
||||
multiple instances of SSRC or ASRC.

|
||||
|
||||
2.4.0
|
||||
-----
|
||||
|
||||
* ADDED: Support for building the core ASRC code in the C emulator as a
|
||||
library
|
||||
* ADDED: Auto-generated ASRC and SSRC performance plots in documentation
|
||||
* ADDED: Documentation warning about overflow in XS3 optimized SRC components
|
||||
* CHANGED: Documents built under Jenkins instead of Github Actions
|
||||

||||
* ADDED: XS3 VPU optimised voice fixed factor of 3 upsampling/downsampling
|
||||
* ADDED: XS3 VPU optimised voice fixed factor of 3/2 upsampling/downsampling
|
||||
* CHANGED: OS3 uses firos3_144.dat coefficients by default inline with model
|
||||
* CHANGED: Replaced xmostest with pytest for all SRC automated tests

Sample Rate Conversion Library
|
||||
==============================
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
The XMOS Sample Rate Conversion (SRC) library provides both synchronous and asynchronous audio sample rate conversion functions for use on xCORE multicore micro-controllers.
|
||||
|
||||
In systems where the rate change is exactly equal to the ratio of nominal rates, synchronous sample rate conversion (SSRC) provides efficient and high performance rate conversion. Where the input and output rates are not locked by a common clock or clocked by an exact rational frequency ratio, the Asynchronous Sample Rate Converter (ASRC) provides a way of streaming high quality audio between the two different clock domains, at the cost of higher processing resource usage. ASRC can ease interfacing in cases where there are multiple digital audio inputs or allow cost saving by removing the need for physical clock recovery using a PLL.
|
||||
|
||||
Features
|
||||
........
|
||||
|
||||
Multi-rate Hi-Fi functionality:
|
||||
|
||||
* Conversion between 44.1, 48, 88.2, 96, 176.4 and 192 KHz input and output sample rates.
|
||||
* 32 bit PCM input and output data in Q1.31 signed format.
|
||||
* Optional output dithering to 24 bit using Triangular Probability Density Function (TPDF).
|
||||
* Optimized for xCORE-200 instruction set with dual-issue and compatible with XCORE-AI.
|
||||
* Block based processing - Minimum 4 samples input per call, must be power of 2.
|
||||
* Up to 10000 ppm sample rate ratio deviation from nominal rate (ASRC only).
|
||||
* Very high quality - SNR greater than 135 dB (ASRC) or 140 dB (SSRC), with THD of less than 0.0001% (reference 1KHz).
|
||||
* Configurable number of audio channels per SRC instance.
|
||||
* Reentrant library permitting multiple instances with differing configurations and channel count.
|
||||
* No external components (PLL or memory) required.
|
||||
|
||||
Fixed factor functionality:
|
||||
|
||||
* Synchronous fixed factor of 3 downsample and oversample functions supporting either HiFi quality or reduced resource requirements for voice applications.
|
||||
* Synchronous fixed factor of 3 and 3/2 downsample and oversample functions for voice applications optimized for the XS3 Vector Processing Unit.
|
||||
|
||||
Building
|
||||
........
|
||||
|
||||
The library can be built under `cmake` or `xcommon` via `xmake` offering backwards compatibility for legacy applications.
|
||||
It is recommended to use `cmake` where the library name `lib_src` is included in the cmake files. See `Related application notes`_ for example usage.
|
||||
The library has no dependencies when building under `cmake` although does require `lib_logging` and `lib_xassert` when using `xcommon`.
|
||||
|
||||
Components
|
||||
..........
|
||||
|
||||
* Synchronous Sample Rate Converter function (ssrc)
|
||||
* Asynchronous Sample Rate Converter function (asrc)
|
||||
|
||||
* Synchronous factor of 3 downsample function (ds3)
|
||||
* Synchronous factor of 3 oversample function (os3)
|
||||
|
||||
* Synchronous factor of 3 downsample function optimized for use with voice (src_ds3_voice)
|
||||
* Synchronous factor of 3 oversample function optimised for use with voice (src_us3_voice)
|
||||
|
||||
* Synchronous factor of 3 downsample function for use with voice optimized for XS3 (ff3_96t_ds)
|
||||
* Synchronous factor of 3 oversample function for use with voice optimized for XS3 (ff3_96t_us)
|
||||
|
||||
* Synchronous factor of 3/2 downsample function for use with voice optimized for XS3 (rat_2_3_96t_ds)
|
||||
* Synchronous factor of 3/2 oversample function for use with voice optimized for XS3 (rat_3_2_96t_us)
|
||||
|
||||
There are three different component options that support fixed factor of 3 up/downsampling. To help choose which one to use follow these steps:
|
||||
|
||||
#. If HiFi quality (130 dB SNR) up/downsampling is required, use ds3 or os3.
|
||||
#. If voice quality (65 dB SNR) is required running on xCORE-200, use ds3_voice or us3_voice.
|
||||
#. If voice quality (75 dB SNR) is required running xcore-ai, use ff3_96t_ds or ff3_96t_us.
|
||||
|
||||
.. warning::
|
||||
Synchronous fixed factor of 3 and 3/2 downsample and oversample functions for voice applications optimized for the XS3 Vector Processing Unit
|
||||
currently overflow rather than saturate in cases where a full scale input causes a perturbation above full scale at the output.
|
||||
To avoid this scenario, please ensure that the input amplitude is always 3.5 dB below full scale.
|
||||
The overflow behavior of these SRC components will be replaced by saturating behavior (to match all other SRC components) in a future release.
|
||||
|
||||
|
||||
Related Application Notes
|
||||
.........................
|
||||
|
||||
An adaptive USB Audio ASRC example can be found in https://github.com/xmos/sln_voice/tree/develop/examples.
|
||||
|
||||
Simple file-based test applications may be found in this repo under `tests/xxxx_test` where xxxx is either `asrc`, `ssrc`, `ds3`, `os3`, `ds3_voice`, `os3_voice`, `vpu_ff3` or `vpu_rat`.
|
||||
These test applications may be used as basic examples to show how these components are used in a minimal application.
