WebThere are several different types of CPUs that gem5 supports: atomic, timing, out-of-order, inorder and kvm. Let's talk about the timing and the inorder cpus. The timing CPU (also known as SimpleTimingCPU) executes each arithmetic instruction in a single cycle, but requires multiple cycles for memory accesses. Also, it is not pipelined. WebThe TimingSimpleCPU is the version of SimpleCPU that uses timing memory accesses (see Memory System for details). It stalls on cache accesses and waits for the memory system to respond prior to proceeding. Like the AtomicSimpleCPU, the TimingSimpleCPU is also derived from BaseSimpleCPU, and implements the same set of functions. It defines …
