Design and implementation of special instructions unit in high performance embedded cpu 特殊指令單元的設計與實現
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 、設計分析適合選擇雙路徑結構的取指部件;通過研究多路徑執行中的pc仲裁機制,設計適合雙路徑執行結構的取指部件。
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.
