A vision based project has an image acquisition device like a webcam as its eyes. Then we need a processor that can make sense out of those captured images and actuators. One key point to note is that Image Processing has huge computational requirements, and it is not possible to run an image processing code directly on a small microcontroller. Hence, for our purpose, the simplest approach would be to run the code on a computer, which has a webcam connected to it to take the images, and the robot is controlled by the computer via serial or parallel port. The code is written in a software that provides the tools for acquiring images, analyzing the content in the images and deriving conclusions. MATLAB is one of the many such software available which provide the platform for performing these tasks.

CCS 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.

1.Software development tools such as assembler, linkers , simulators and compilers

2.DSP boards for software development and testing before target DSP hardware is available

3.Hardware testing tool such as emulator and logic analyzers.

4.Development assistance such as application libraries , real time debugging hardware available

The Texas Instruments C6713 DSK platform, which can be programmed using SIMULINK.

This gives us added advantage of easily writing codes on MATLAB and implementing it on the DSP processors.

Based on a very-long-instruction-word (VLIW) architecture, the C6x is considered to be TI’s most powerful processor.
