从计算机硬件结构出发,研究了微程序级中不同层次的控制信息,给出了微命令和微操作的形式定义,然后根据微操作的物理并行性提出了构造微指令的方法。这样定义的微指令充分描述了计算机内部固有的并行性,可以作为微程序员直接使用的微程序计算资源,并加以集成化。本文区别了微操作的物理并行性和逻辑并行性。在微指令级识别物理并行性和处理资源冲突,有利于提高微程序设计的灵活性和微程序的效率,有利于实现微程序设计高级语言的设计目标。
Based on the structure of computer hardware, the control information at different levels of micro-program level is studied. The formal definitions of micro-commands and micro-operations are given. Then, the method of constructing micro-instructions is proposed according to the physical parallelism of micro-operations. The microinstructions defined in this way fully describe the inherent parallelism inside the computer and can be used as micro-program computing resources directly used by micro programmers and be integrated. This article distinguishes the physical parallelism and logical parallelism of micro-operations. Identifying physical parallelism at the micro-instruction level and handling resource conflicts help to improve the flexibility of micro-program design and the efficiency of micro-programs and facilitate the design goals of high-level programming languages for micro-programming.
