This module describes the TI C6713 DSK hardware and how to set up a Code Composer Studio v4 DSP/BIOS project for the DSK.


This module describes the TMS320C6713 DSK development board and how to use it in a Code Composer Studio (CCS) v4 project that uses DSP/BIOS. An example project is included.

Dsk hardware

The following figure shows the block diagram of the TMS320C6713 DSK hardware. The heart of the DSK is the TMS320C6713 DSP chip which runs at 225 MHz. The DSP is in the center of the block diagram and connects to external memory through the EMIF interface. There are several devices connected to this interface. One device is a 16 Mbyte SDRAM chip. This memory, along with the internal DSP memory, will be where code and data are stored.

On the DSK board there is a TLV320AIC23 (AIC23) 16-bit stereo audio CODEC (coder/decoder). The chip has a mono microphone input, stereo line input, stereo line output and stereo headphone output. These outputs are accessible on the DSK board. The AIC23 figure shows a simplified block diagram of the AIC23 and its interfaces. The CODEC interfaces to the DSP through its McBSP serial interface. The CODEC is a 16-bit device and will be set up to deliver 16-bit signed 2's complement samples packed into a 32-bit word. Each 32-bit word will contain a sample from the left and right channel in that order. The data range is from - 2 ( 16 1 ) size 12{2 rSup { size 8{ \( "16" - 1 \) } } } {} to ( 2 ( 16 1 ) size 12{2 rSup { size 8{ \( "16" - 1 \) } } } {} -1) or -32768 to 32767.

Dsk6713 audio project framework

The following figure shows a diagram of the software that will be used in this module. Texas Instruments has written some drivers for the McBSP that get data from the AIC23 and write data to the AIC23. The input data is put into an input stream (input buffer) and the output data is read from an output stream (output buffer). The signal processing software simply needs to get a buffer from the input stream, process the data, then put the resulting buffer in the output stream.

The project is set up using DSP/BIOS, a real time operating systems developed by TI. This module does not explain how to use DSP/BIOS but it will explain what objects are used in this project. The main objects are an input stream, inStream , an output stream, outStream , and a task, TSK_processing , which uses the function processing() .

There are a few things that can be easily modified by the user in the main program file DSK6713_audio.c .

Codec setup

The CODEC can be set up for different inputs and different sample rates. In the program there is a variable that sets up the registers in the CODEC:

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
