Mdsched Review

Modern CPUs use out-of-order execution (OoOE) to improve performance. In OoOE, instructions are executed as soon as possible, regardless of their original order in the program. This allows for better utilization of CPU resources, such as functional units and registers.

MDSched is designed to resolve these memory dependencies by scheduling instructions in a way that ensures correct execution. The algorithm works as follows: mdsched

However, OoOE introduces complexity when dealing with memory accesses. When instructions access memory, they may depend on the results of previous instructions, which can lead to memory dependencies. Modern CPUs use out-of-order execution (OoOE) to improve
