WebThis is gem5’s detailed in-order CPU model. By default this CPU models a four stage pipeline (Fetch1, Fetch2, Decode, Execute), however, the delay between the pipeline stages is configurable. One noteworthy point is that the real instruction decoding happens at Fetch2 stage of MinorCPU and Decode stage is there mostly for bookkeeping. KvmCPU WebThere are two types of ports in gem5: master ports and slave ports. Whenever you implement a memory object, you will implement at least one of these types of ports. To do this, you create a new class that inherits from either MasterPortor SlavePortfor master and slave ports, respectively.
