Abstract
A multithreading processor 4 interleaves program instructions from different program threads to perform fine grained multithreading. Thread performance monitoring circuitry 30 monitors performance parameters of individual program threads to generate performance values. Issue control circuitry 28 reads these performance values to determine which program thread is next selected to be active when a thread switch event occurs. The performance parameters measured may include the proportion of cycles in which a program thread is able to provide a program instruction for execution by the execution circuitry 12 within the processor 4.
