Multithreading Architecture: Fine-Grain Multithreading [A Fine-Grain Multithreading architecture is one in which an instruction (or instructions, but most FGMT processors are scalar or VLIW) from a different thread can be issued every cycle, but only a single thread can issue an instruction in a particular cycle. That is, the architecture can perform a context switch in one cycle—in many cases, the pipeline actually seeks to do a context switch between threads every cycle. Therefore, on a pipelined machine, the FGMT processor would have instructions from multiple threads in the pipeline at once.] http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png

Abstract

[A Fine-Grain Multithreading architecture is one in which an instruction (or instructions, but most FGMT processors are scalar or VLIW) from a different thread can be issued every cycle, but only a single thread can issue an instruction in a particular cycle. That is, the architecture can perform a context switch in one cycle—in many cases, the pipeline actually seeks to do a context switch between threads every cycle. Therefore, on a pipelined machine, the FGMT processor would have instructions from multiple threads in the pipeline at once.]
