Multithreading techniques use coarse grain parallelism to speed up computation of a multithreaded workload by better utilization of the resources of a single processor. The paper surveys context switching techniques for multithreaded single-issue processors and classifies the techniques due to the events that trigger a context switch. We survey static and dynamic block interleaving techniques and demonstrate the application of several techniques in the decoupled multithreaded Rhamma processor. We show that a speed-up of up to 2.1 can be reached with four threads over a single-threaded base processor
