Tomasulo Algorithm Example 托马斯洛算法举例
必须保证具有依赖关系的指令之间有正确的指令顺序 必须可以区分下面这个指令顺序和example1。必须允许MD可以独立与LD执行 前两个要求是为了保证程序逻辑完整性,第三个要求是为了达到性能目标。下一章将会阐述完成这些目标的几个方法。 参考:An Efficient Algorithm for Exploiting Multiple Arithmetic Units ...

• Tomasulo Algorithm lets us schedule instructions dynamically (in hardware). • Branch prediction and speculative execution beyond a branch (of course with ability to flush wrong-path 7 ( y g p instructions on misprediction) will be covered later (and ...
