| Abstract: | YHFT-DSP700 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-DSP700 are presented. The latest simultaneous multi-threading DSP architecture called YHFT-DSPSMT is proposed, which improves the system throughput by 40%. The architecture and development trends of the mainstream high performance DSPs are analyzed as well. |
