It has gained great interests from both the industry and the academic. This paper introduces the successful commercial DSP architectures and the latest research in academic. YHFT-DSP/700 is a high performance floating point DSP developed by NUDT＇s DSP Design Group leaded by Prof. Chen Shuming. YHFT-DSP/700 has 8 execulion units, including 4 ALUs, 2 multipliers and 2 load/store units. Its VLIW architecture can issue 8 instructions per cycle. When running at the frequency of 238MHz, its peak performance is 1, 428MFL0PS and 1,904MIPS. YHFT-DSP/700 uses a packed variable length instruction packet technique, which can reduce the program memory usage. The support of 8 bit and 16-bit SIMD instructions can double the chip＇s performance for some multimedia algorithms. YHFT-DSP/700 has a two level memory hierarchy. YHFT-DSP/700 is fabricated in 0.18 micron CM0S process. The register file and the barrel shifter are designed in full custom. To help the programmers, a VLIW compiler is designed. 0n this basis, we implement an integrated development environment, and M0SI, a new simultaneous multi-threading DSP architecture, is also presented. It can improve the system throughput by 40 % . This work is supported by the National High Technology Research and Development Program of China （2004AAIZ1040） and the National Natural Science Foundation of China （60473079）.

英文摘要：

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 1,904MlPS. 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.
