DSP软件开发工具链的设计与实现

摘要

As an important medium in human-computer interaction for the development of DSP applications, the design of software development tool chain has become a key part of the development of SoC on DSP. In order to design DSP software development tool chain preferably , this paper proposes an approach based on machine description language LISA. Firstly, we use the RESOUCE and OPERATION sections in LISA to model the hardware resources and instruction set respectively, which could provide a complete description of the abstract model of DSP. Subsequently, the integrated software development tool chain, comprising an assembler, a disassembler, a linker, a simulator and a debugger front -end , could be generated from the LISA description on the PD platform. Finally, a DSP-based processor ZWxxCore is taken for instance to verify the feasibility of this method.%软件开发工具链作为DSP应用开发中人机交互的重要媒介,其设计已成为DSP片上系统开发的关键部分；文章给出了一种基于机器描述语言LISA设计DSP软件开发工具链的方法；首先,使用LISA表述中的RESOURCE和OPERATION分别模拟硬件资源和指令集,从而完整描述DSP的抽象模型；然后,利用PD平台将LISA描述生成包括汇编器、反汇编器、链接器、模拟器和调试器前端在内的完整的软件开发工具链；最后,以一款DSP型处理器ZWxxCore为例,验证了该方法的可行性.
