设计模式在基于SystemC的指令译码模块设计中的应用

DESIGN PATTERN APPLICATION ON THE DESIGN OF INSTRUCTION DECODING MODULE ON SYSTEMC BASIS

SoC上的晶体管集成度在不断增长,系统功能越来越复杂,传统的设计方法已经不再适应现在的SoC设计。为了解决这种不适应性带来的"硬件危机",人们初步探索将软件中的面向对象技术引入到SoC设计领域中。设计模式是面向对象技术的核心,可以给同类问题提供比较合理的解决方案。在对软件中的设计模式进行分析的基础上,将用于SoC中的CPU指令译码模块进行基于模式的设计,并给出了部分实现。

The traditional design method is no longer suitable for the modem System on a Chip （SoC） design due to the growing integration degree of the transistors and the complexity of the system ftinctions on SoC. An initial grope in importing object-oriented technology in software to SoC design realm has been carrying out for conquering the＂ hardware crisis＂ incurred from the unsuitability. As the core of object-oriented technology the design pattem provides a reasonable approach to resolve the similar problems. This paper analyzes the design pattern in the software, presents a pattern-based design according to the analysis using CPU instruction decoding module in SoC, and some of its implementation.
