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 发布于 2022

One important reason Tomasulo algorithm came into main stream processor usage today is because of the common usage of cache. Once caches became commonplace, Tomasulo's algorithm's ability to maintain concurrency during unpredictable load times caused by cache misses became valuable in processors. 3, ...

换句话说，直到其内容反映了最新指令操作的结果，寄存器才能被使用。目前为止，论文尚未说明解决这个问题的方法。但任何方法都必须解决以下三项：保证程序逻辑完整性、保证性能目标。下一部分将阐述实现这些目标的几个方法。参考：An Efficient Algorithm for Exploiting Multiple Arithmetic Units ...
