Abstract

Abstract: The authors first analyse the development of application-specified DSP, and then propose a configurable DSP, CmDSP, aiming at the field of media processing. Based on independent media instruction set, CmDSP uses SIMD technology and is implemented with acceleration units, including complex multiplier and algorithm specified co-processor. In addition, it has a dual-cluster structure and VLIW architecture. CmDSP is implemented using SIMC 0.18 ?m Digital Logic library, and instruction level tests are completed in test board, along with the realization of several media applications, which indicates that it can satisfy the engineering demand in this field.

Key words: configurable, algorithm specified, digital signal processor (DSP), media

摘要： 通过分析专用DSP技术发展, 提出一个面向媒体处理的可配置DSP: CmDSP。在自主定义专用媒体指令集基础上, 采用SIMD技术以及相应复数乘法器和专用协处理器等加速单元, 并采用VLIW技术和双簇结构。 CmDSP基于SMIC 0.18 m Digital Logic工艺实现, 并自主设计测试板, 完成了指令级测试和若干媒体算法的应用实现, 可以满足该领域设计工程的需要。
