Processor architectures that are capable to reconfigure their instruction set and instruction format dynamically at run time offer a new flexibility exploiting instruction level parallelism vs. thread level parallelism. Based on the characteristics of an application or thread the Instruction Set Architecture (ISA) can be adapted to increase performance or reduce resource/power consumption. To benefit from this run-time flexibility automatic selection of an appropriate ISA for each function of a given application is envisioned. This demands a cycle-accurate simulator that is capable of measuring the performance characteristics of an ISA dependent on the target application.
