| 摘 要： | 针对软件无线电中存在通用数字信号处理器（DSP）计算能力不足以及专用基带处理器缺乏扩展性的问题，提出了一种新的处理器：面向软件无线电的可重构流处理器及相应的专用指令集。仿真证明，该处理器的可重构设计具备指令集扩展能力，可以对多种无线通信标准甚至是新的通信标准提供支持；面向软件无线电的流体系结构和专用指令集保证了对多种高速无线基带信号的实时处理，运算能力是通用DSP的5~13倍。该处理器为软件无线电中的硬件设计难题提供了一种新的解决途径。

| Abstract: | Software radio is hard to be implemented. This is because that existing general purpose digital signal processors (DSP) are not competent for the works with highly computing intensity and baseband processor has poor scalability and flexibility. In order to get over the disadvantages of general purpose DSP and the baseband processor,the article puts forward a novel architecture of reconfigurable stream processor along with application-specific instruction set for software radio. The simulation results of the... |
