摘要
文章分析了精简指令集的结构特征和嵌入式系统的应用需求,在设计出的8位RISC微处理器核的基础上,从指令集、存储空间等体系结构方面做了参数化设计和参数提取,讨论了硬件描述语言和运行于微处理器核上的程序对参数化设计的支持。参数化的设计方法增强了IP核的灵活性和可重用性,可以在大批量设计片上系统的过程中充分使用参数化设计方法。
According to the instruction execution characteristics of Reduced Instructions Set and the application requirement of embedded systems,we presented a parameterized 8- bit RISC microprocessor core,in which parameters are defined and abstracted in the architecture aspects of instructions set,memory space,etc. Then this paper presents the support to parameterized design by HDL and the program running on the processor core. The parameterization methodology enhances IP cores' flexibility and reusability,suitable for applying into the process of batch designs of System- On- a- Chip ICs.
