| 摘 要： | 为满足多媒体处理等领域要求芯片高性能,且开发周期短的需求,提出一种可重构阵列DSP的结构——ReMAP.该阵列结构由多个运算单元、存储器和交换开关等级联组成,易于扩展和配置.通过把算法分割映射到多个运算单元之中,提高芯片对计算密集型任务的执行效率.在SMIC 0.18μm工艺下完成了ReMAP芯片的原型验证,包含16个ALU单元.测试结果表明,该结构能以较高效率完成如SAD和DCT等视频处理相关算法.

| Abstract: | Current IC design,especially that for multimedia processing,requires high performance and short development time.To satisfy these design requirements for an optimal time-to-market,a reconfigurable Array DSP architecture (ReMAP) with processing elements,memory,switch,and other components was proposed.Pipeline reconfiguration was introduced for performance improvement of applications.The antitype chip with 2×2 PEs was fabricated in SMIC 0.18 μm CMOS,which contains 16 reALUs.Some common algorithms such as DCT and SAD were implemented in ReMAP.The result shows that the architecture can support high performance implementation of media processing. |
