WebThis CPU model executes a single instruction per cycle except memory instructions which are modeled using Timing memory access mode and can take more than one cycle. … Webgem5 provides four interpretation-based CPU models: a simple one-CPI CPU; a detailed model of an in-order CPU, and a detailed model of an out-of-order CPU. These CPU models use a common high-level ISA description. In addition, gem5 features a KVM-based CPU that uses virtualisation to accelerate simulation. Event-driven memory system.

WebNow that we have defined these two new types CPUSidePort and MemSidePort, we can declare our three ports as part of SimpleMemobj . We also need to declare the pure virtual function in the SimObject class, getPort. The function is used by gem5 during the initialization phase to connect memory objects together via ports. WebMost simulator models will execute instructions either at the beginning or end of the pipeline; SimpleScalar and our old detailed CPU model both execute instructions at the beginning of the pipeline and then pass it to a timing backend.

WebMemory system. M5’s new memory system (introduced in the first 2.0 beta release) was designed with the following goals: Unify timing and functional accesses in timing mode. With the old memory system the timing accesses did not have data and just accounted for the time it would take to do an operation. Then a separate functional access ...
