PTLsim: A Cycle Accurate Full System x86-64 Microarchitectural Simulator

In this paper, we introduce PTLsim, a cycle accurate full system x86-64 microprocessor simulator and virtual machine. PTLsim models a modern superscalar out of order x86-64 processor core at a configurable level of detail ranging from RTL-level models of all key pipeline structures, caches and devices up to full-speed native execution on the host CPU… CONTINUE READING
