The Optimization of TMS320C6x DSP Programs in a Real-Time Image Tracking System

TMS320C6x DSPs adopt the VelociTITM architecture, integrate various powerful peripherals such as the DMA controller and have internal data memory which is organized as blocks and banks. In order to fully benefit from such devices and increase the performance of the whole system, it is necessary to take a series of steps to optimize the DSP programs, realize better instruction-level parallelism and pipeline operation. This paper introduces some effective methods for TMS320C6x C optimization and then offers the results of an application in a real-time image tracking system.
