Design and implementation of special instructions unit in high performance embedded cpu 特殊指令单元的设计与实现
Based on the ( program counter ) pc arbitrage strategy of multi - path execution , designing fetch instruction unit suit for selective dual path execution . the dissertation work plays a great significance for studying the high performance microprocessors 6 、设计分析适合选择双路径结构的取指部件;通过研究多路径执行中的pc仲裁机制,设计适合双路径执行结构的取指部件。
The instruction unit (IU) in a central processing unit (CPU) is responsible for organising program instructions to be fetched from memory, and executed, in an appropriate order. It is a part of the control unit, which in turn is part of the CPU.
