摘　　要：叙述了一种用于移动通信的无线电多媒体DSP芯片的实现。开发出的WM DSP芯片既支持用于Viterbi、时间同步等的通信指令,也支持多媒体指令。这个DSP能够处理可变长数据,并且在一个周期里可以执行4个MAC。提出的DSP采用了并行处理技术,如SIMD、矢量处理和DSP结构,并且采用了无线电应用的低功耗特性。整个DSP芯片包括测试电路和各种外围设备,如DMA、总线仲裁、定时器等等。除了存储器之外总共大约有170 000个门电路,并且时钟频率达到了100 MHz。This paper presents the implementation of a wireless multimedia DSP chip for mobile communication. The implemented DSP chip supports communication instructions for Viterhi,timing synchronization,as well as multimedia instructions. The DSP can handle variable length data and perform four MACs in a cycle. The proposed DSP employs parallel processing techniques, such as SIMD, vector processing, DSP schemes and adopts low power features for wireless applications. The implemented DSP chip includes test circuits and various peripherals, such as DMA, bus arbitration,timer, and so on. The total gate count excluding memory is about 170 000 gates and the clock frequency is 100 MHz.
