This section describes the Core components.
These are Code Translation (CT) components, which match functional behavior with what you can observe from software. They sacrifice timing accuracy to achieve fast simulation speeds.
CT processor components translate instructions on the fly and cache the translations to enable fast execution of code. They also use efficient PV bus models to enable fast access to memory and devices.
The CT processor components implement most of the processor features but differ in certain key ways to permit the models to run faster:
All Performance Monitor Unit (PMU) registers in models allow software to program the PMU without aborting. Models implement the cycle count (CCNT) but not the programmable timers. Software can program registers of the PMU but the count value returned is not valid.
