Optimization Design of Complex Multiplication Based on Compiling Guidance
摘要
Abstract
According to the problem that the digital signal processor cannot make full use of the complex multiplication instruction offered by Digital Signal Processing(DSP) chip causing the low performance of complex multiplication, this paper proposes the optimization of complex multiplication based on compiling guidance. By passing the compilation guidance commands, it makes the complier identify all the instructions which are related with complex multiplication, and replaces all the multiplication instructions with a single complex multiplication instruction through the recognition algorithms in a control block. Experimental results show that the optimization design can effectively reduce the fft_radix2 and fft_radix4 programs execution cycles.关键词
