资源说明：This paper illustrates the set of instructions in the PowerPC® 4xx cores commonly known as DSP (Digital Signal Processing) instructions.These instructions are included in 400 series PowerPC cores and processors, but at this time have not been used extensively by compilers. This paper demonstrates the Autocorrelation algorithm and shows how to get a performance boost of up to 53% by hand coding the Autocorrelation function in assembler.
