Research and Development of High Performance YHFT Digital Signal Processor

YHFT-DSP/700 is a high performance floating-point VLIW DSP developed in 2004. Its frequency is 238MHz and its peak performance is 1,428MFLOPS and 1,904MIPS. The architecture, design methodology and compiler techniques of YHFT-DSP/700 are presented. The latest simultaneous multi-threading DSP architecture called YHFT-DSP/SMT is proposed, which improves the system throughput by 40%. The architecture and development trends of the mainstream high performance DSPs are analyzed as well.
