Submitted To:

Eng. Tamar Jomaa.

IUG 2013

Objectives :

Testing the software and hardware tools with Code Composer Studio

CSS.

TMS320C6711 DSP chip and supporting architecture (DSK).

C Programming examples to test the tools.

Practical Parts:

Solution:

1- Features of the C6711 include 72 kB of internal memory, eight

functional or execution units composed of six ALUs and two

multiplier units, a 32-bit address bus to address 4 GB (gigabytes),

and two sets of 32-bit general-purpose registers.The C6711 is

capable of both fixed- and floating-point processing.

2-

1. file.pjt: to create and build a project named file.

2. file.c: C source program.

3. file.asm: assembly source program created by the user, by the C

compiler, or by the linear optimizer.

4. file.sa: linear assembly source program. The linear optimizer uses

file.sa as input to produce an assembly program file.asm.

5. file.h: header support file.

6. file.lib: library file, such as the run-time support library file

rts6701.lib.

7. file.cmd: linker command file that maps sections to memory.

8. file.obj: object file created by the assembler.

9. file.out: executable file created by the linker to be loaded and run on

the processor.

Solution : 1-

2- f= Fs/#points

250 = 8000/#points

# points = 32

f= Fs/#points

2000= 8000/#points # points = 4

3-

a) 250 HZ.

b) 2KHZ.

Example : SINE Generation with Eight Points (sine8_intr).

//sine8_intr.c Sine generation using 8 points, f = Fs/ (# of points)

//Comm routines and support files included in C6xdskinit.c

short loop = 0;

short sin_table[8] = {0,707,1000,707,0,-707,-1000,-707}; //sine values

short amplitude = 10; //gain factor

interrupt void c_int11() //interrupt service routine

{

output_sample(sin_table[loop]*amplitude); //output each sine value

if (loop < 7) ++loop; //increment index loop

else loop = 0; //reinit index @ end of buffer

return; //return from interrupt

}

void main()

{

comm_intr(); //init DSK, codec, McBSP

while(1); //infinite loop

}

comment : In this lab we learn how to testing the software and hardware tools

with Code Composer Studio CSS and TMS320C6711 DSP chip and

supporting architecture (DSK) and it was wonderful experiment .
