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 发布于 2022-11-13 17:18・IP 属地广东 ...
第二个也是最重要的创新就是利用保留站和简单的tag电路去提高并行度,同时保留基本的优先级关系。结合CPU中各种buffer,CDB帮助model 91降低编程敏感。但程序员依然要练习去控制更多的指令并行执行。 参考:An Efficient Algorithm for Exploiting Multiple Arithmetic Units ...
Store:Proceed only whenno prior instruction load/storeto the same location 但是在load/store中也会设计地址的计算(也就是前面的ALU指令了)。因此我们把这个规则套用到tomasulo里面: 如图,Addr Unit负责计算地址,送入Store buffer和Load buffer。 以一个RAW的例子为例: i1: R1 := load0(R0) //write R1 i...

The goal of this project is to design and implement a C/C++ cycle-accurate simulator of a dynamically scheduled processor implementing the Tomasulo algorithm with Reorder Buffer. Students taking the course at the undergraduate level (ECE463) do not need to support store instructions (SW and SWS)...
