ABSTRACT:
A computer processor that includes a plurality of execution pipelines, each execution pipeline including a configuration of one or more execution units of the processor, each execution pipeline characterized by an execution pipeline type, each execution pipeline type determined according to the types of computer program instructions executed in each execution pipeline; a plurality of hardware threads of execution, each hardware thread including computer program instructions characterized by instruction types, each hardware thread including sequences of instructions of a same instruction type, the sequences interspersed with instructions of other types; and an instruction dispatcher capable of dispatching instructions preferentially during a predefined preference period from a preferred hardware thread to a particular execution pipeline in dependence upon whether the preferred hardware thread presents a sequence of instructions, ready for execution from the preferred hardware thread, of a type for execution in the particular execution pipeline.
