"计算机体系结构：Tomasulo's Algorithm及数据依赖分析"

The end-of-term review for the Computer Architecture course at Chongqing University covered a range of topics, including an in-depth examination of Tomasulo's Algorithm. The lecture focused on name dependences and the new hazards that arise from out-of-order execution in computer systems. One of the key concepts discussed in the review was the distinction between true data dependencies and name dependences. True data dependencies occur when an instruction produces a value that is used by a subsequent instruction, potentially leading to a RAW hazard. On the other hand, name dependences involve two instructions that share the same register or memory location, but do not actually transmit a real value between them. This type of dependence can result in a WAR hazard, also known as an output dependence. The lecture emphasized the importance of understanding these different types of dependencies and hazards in order to design and optimize computer systems. With the increasing complexity of modern processors, out-of-order execution has become a common feature, leading to the emergence of new challenges and considerations for architects and developers. Overall, the end-of-term review provided a comprehensive overview of the key concepts and challenges in computer architecture, touching upon important topics such as dependency analysis, hazard detection, and the implications of out-of-order execution. Students were encouraged to apply this knowledge in their future studies and professional endeavors, as the field of computer architecture continues to evolve and advance.
