Digital signal processor (DSP Processor)

Digital signal processor (DSP)/DSP Processor is a special type of microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing.

Digital Signal Processors (DSP processor) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like “add”, “subtract”, “multiply” and “divide” very quickly.

What is inside a DSP processor?

A DSP contains these key components:

• Data Memory: Stores the information to be processed by processor
• Program Memory: Stores the programs which the DSP will use to process data
• Input/Output: Serves a range of functions to connect to the outside world
• Compute Engine:It performs the math processing, accessing the program from the Program Memory and data from  Data Memory

Required Softwares

Download board support files from Spectrum Digital Website.
Unpack all files to C:
Download CSL form TI website
Install it at C:C6xCSL directory
Set all of jumpers on SW3 and SW1 to OFF
Connect USB then connect power

Run 6713SDKDiag.exe from C:DSK6713drivers to check emulator connection

Following is a step by step guide to setup a DSP processor using Non real steps CCS v5.3 DSK6713

Step 1
Click on ccs5.3.0 icon as shown below

Workspace window will get open select as default or you can give your location.

DSP Processor

Close TI Explorer window

Create new target configuration
File–> new–> targetconfiguration

Filename: test1.ccxml

 

It will jump from edit perspective to debug perspective.

 

Run –> connect target

 

 

Your target is connected.

Create  new project

File–>new –> ccs project

Select as shown below.(DSP Processor)

Write the code in main.c file or copy paste.

Right click on project –> build project

It will generate the .out file in debug folder.

Move from edit perspective to debug prospectively.

How To Face An Interview

[su-divider]

Run –> load –>load program.

Browse project

Select Debug –> xyz.out

Ok–>ok

Run –> resume.

See the output on a console.

To see the graph.

Tools –> graph –> single time

Select as shown

Real time

It is same like non real but you need to add BSL and CSL file.

Copy real time codec code to main.c.

Right click on project –> add files

C:CCStudio_v3.1C6000dsk6713libdsk6713bsl.lib

C:CCStudio_v3.1C6000csllibcsl6713.lib

Add header file for csl and bsl.

Right click on project properties –> include option

Add dir to #include click on green colour plus sign symbol.

C:CCStudio_v3.1C6000dsk6713include.

C:CCStudio_v3.1C6000cslinclude.

Predefined symbol –>  pre-define Name

click on green colour plus sign symbol.

Type CHIP_6713 and save.

Now debug the code and  load the .out file to board same like non real procedure.

Possibility error

Install again and again

Disable antivirus or uninstall

Add gel files:

CCStudio_v3.1ccgelDSK6713.gel

Add

Linker command file : C:CCStudio_v3.1tutorialdsk6713hello1hello.cmd

and

Run time support libarray: C:/CCStudio_v3.1/C6000/cgtools/lib/rts6700.lib
