The application of TMS320C64x DSP assembly language in correlation tracking algorithms

In order to improve the real-time performance of the conventional correlation tracking algorithm based on full search method, for its huge computation amount and vast correlation matching times in the process of searching an optimal matching position, a method of combining the TMS320C64x DSP assembly language and software pipelining is proposed to realize template matching which costs the most time of the algorithm. Choose high performance DSP chip TMS320DM642 as the core processor of the hardware platform, and schedule each one of the instruction in the algorithm to maximize performance using the instruction-level parallelism of the DSP. The experimental results indicate the time of template image matching implemented in assembly language has decreased from 49.36ms to 0.62ms. It is concluded that the correlation tracking adopting proposed method can meet the real-time and stability requirement of the target tracking.
