GOALS
- The main goal of this project is to create a relatively simple step by step guide of how to get an Analog Devices "adsp-21369" dsp (SHARC) chip up and running using the "ADDS-21369-EZLITE" development board and "Visual DSP++" development environment.
- A second goal is to create an easy to use tool that can be used to interface with the FAUST programming language in order to generate c++ code that can be imported into a Visual DSP++ project file and used with the SHARC chip.
Technical Specification of the ADSP-21369 EZ-Kit Lite development board
-The main DSP processing is performed by a SHARC processor, based on a 32-bit super Harvard architecture, with a core clock speed of 400 MHz.
-Audio I/O inteface:
4x2 RCA phono jacks for 4 channels of stereo output 2X1 RCA phono jacks for 1 channel of stereo input 3.5mm headphone jack for 1 channel of stereo output RCA phono jack input and output for SPDIF digital input and output
-The digital-to-analog and analog-to-digital conversion is performed by a single AD1835A codec chip:
4 stereo digital-to-analog converters (DACs) 1 stereo analog-to-digital converter (ADC) input/output sample-rates of up to 96 kHz on all channels 196 kHz sample-rate on one of the DAC channels
-The memory is broken up into multiple sections. The flash memories can store user-specific boot code, allowing the board to run as a stand-alone unit.
1M x 32-bit x 4 banks of synchronous dynamic random access memory (SDRAM) 512 Kbit x 8-bit synchronous random access memory (SRAM) 1M x 8-bit flash memory 2 Mbit serial peripheral interface (SPI) flash memory
-Universal asynchronous receiver/transmitter (UART):
ADM3202 RS-232 driver/receiver DB9 female connector
-11 LEDs: 1 power (green), 1 board reset (red), 1 USB monitor (amber), and 8 general purpose (amber). 5 push buttons: 1 reset, 2 connected to DAI,2 connected to the FLAG pins of the processor.
-USB connection for interfacing with a computer.
-VisualDSP++ 5.0 integrated software development and debugging environment for Windows XP, allows programming of the board in assembly, C, and C++ (as well as combinations thereof).
-VisualAudio 2.5 audio software development tools and libraries, works in conjunction with VisualDSP++. Provides a set of graphical tools for developing audio processing data-flows, using a block-diagram approach. Contains tools for analysis, as well as the ability to treak the parameters of an algorithm in real-time. Comes with a collection of pre-built examples of various audio effects.
Setting Up Development Board and Visual DSP++ Development Environment
The development software used is VisualDSP++ Release 5.0 which can be downloaded here. It is compatible with Blackfin, SHARC and TigerSHARC processors.
FAUST Integration Tool
We (or, more precisely Andrew, A.K.A the captain of the A-TEAM), developed a script which takes in Faust code (on .dsp format), and returns C code, ready to plug into VisualDSP++. The script is called faust2sharc, release 0.0.2 can be downloaded from here.
When modifying a code or trying out new code, it is recommended that you make sure your Faust code definitely compiles as such, by for example generating a C++ code or a block diagram using Faust.
Instructions on running faust2sharc
1) Download and install faust2sharc from the link above.
The interface should look like this:
https://cm-wiki.stanford.edu/mediawiki/images/c/c5/Faust2sharc_small_blank.jpg
2) Upload the [name_of_file].dsp file with the open file button.
3) Press generate project. This generates a [name_of_file].c file.
4) Upload the [name_of_file].c file to VisualDSP++.
5) The Faust generated diagrams can be viewed by pressing on the view diagram button. This generates a folder in your workspace called [name_of_file].dsp-svg which includes block diagrams for the project.
