Abstract :
The embedded target for TI TMS320C6000 DSP is a useful development tool, which can be used to generate executable codes for a range of targets, from a set of Simulink model blocks. In this paper we outline the process of code generation for the TMS320DM642 evaluation module (EVM) using a Hough transform algorithm. This was computed using the forward Radon transform, evaluated using the central slice theorem, and involves a 2-D discrete Fourier transform (DFT), a rectangular to polar coordinate transformation, and a 1-D DFT. This was implemented using Simulink model blocks together with custom blocks, which were written using the S-function builder. The embedded target generates all the video capture and display routines required, so that the algorithm can be developed in Matlab and Simulink, before being tested on the EVM. Problems and limitations with the embedded target are highlighted, and solutions and code profiling optimizations are proposed.
