Introduction to Introduction to TMS320C6713TMS320C6713 DSP Starter KitDSP Starter Kit
((DSK)DSK)
IntroductionIntroductionThe TI's TMS320C6713 DSK is
designed and optimized to perform digital signal processing operations.
For short this DSP will be referred to as 'C6713.
The family of this DSP is referred to as 'C6x or 'C6000.
'C6713 is a high performance 32-bit floating-point DSP.
VLIW architecture. low-cost standalone development
platform that enables users to evaluate and develop applications for the TI C67xx DSP family.
PurposePurposeStart getting familiar with TI's
TMS320C6713 by learning the following.
◦An overview of the functional blocks of the board.
◦Code Composer Studio (CCS).◦Writing, compiling and running a simple
code.

Functional OverviewFunctional Overview Interfaces to on-board peripherals through a 32-
bit wide EMIF (External Memory Inter Face).
The SDRAM, Flash and CPLD are all connected to the bus.
EMIF signals are also connected daughter card expansion connectors which are used for third party add-in boards.
The DSP interfaces to analog audio signals through an on-board AIC23 codec and four 3.5 mm audio jacks (microphone input, line input, line output, and headphone output).
Contd…Contd…
A programmable logic device called a CPLD is used to implement glue logic that ties the board components together
The DSK includes 4 LEDs and a 4 position DIP switch as a simple way to provide the user with interactive feedback
Code Composer communicates with the DSK through an embedded JTAG emulator with a USB host interface

Simplified Code Composer Studio IDE Development Flow
Code Composer Studio Code Composer Studio (CCS)(CCS)CCS provides an IDE to incorporate the software
tools.
CCS includes tools for code generation, such as a C compiler, an assembler, and a linker.
It has graphical capabilities and supports real-time debugging
The C compiler compiles a C source program with extension .c to produce an assembly source file with extension .asm.
The assembler assembles an.asm source file to produce a machine language object file with extension.obj.
Contd…Contd…
The linker combines object files and object libraries as input to produce an executable file with extension .out.
This executable file can be loaded and run directly on the C6713 processor.

Code Composer Studio - Code Composer Studio - ExampleExampleCCS is TI’s proprietary IDE that
provides a transition between a high-level DSP program and an on-board machine language program.
It is used to: ◦Generate programs for the C6713 DSP
using C language,◦Load them into the DSK,◦Run them,◦Monitor program execution.
12
Code Composer Studio - Code Composer Studio - ExampleExampleMake sure DSK is connected to PC
via USB and to power outlet before opening CCS.
Open CCS by double clicking on the CCS icon
To connect to the DSK, go to: “Debug → Connect”.
To start a new project, go to: “Project → New…”Choose
Appropriate DSP Family
13
Code Composer Studio - Code Composer Studio - ExampleExample
Add C source file to “dsplab.c”:Add a linker command (.cmd)
◦linker command file - sets up the memory map for the CCS linker to make sure the code and data are loaded to the desired locations.
Add the run-time support library functions file rts6700.lib to the project
14
Code Composer Studio - Code Composer Studio - ExampleExample
Now,◦Compile code: “Project → Compile File”,◦Build project: “Project → Build”,◦Load program to DSK: “File → Load
Program” and choose “.out” file in “Debug” folder,
◦Run the program on DSP: “Debug → Run”.
Debugging featuresDebugging features
Setting breakpoints and watching variables; viewing memory, registers, and mixed C and assembly code;
Graphing results; and monitoring execution time.
One can step through a program in different ways (step into, over, or out).
