摘要: A processor core, comprises one or more vector units operable to change between a fine-grained vector mode having a shorter maximum vector length and a coarse-grained vector mode having a longer maximum vector length. Changing vector modes comprises halting all instruction stream execution in the core, flushing one or more registers in a register space, reconfiguring one or more vector registers in the register space, and restarting instruction execution in the core.

摘要: A multiprocessor computer system having a plurality of processing elements comprises one or more core-level hierarchical shared semaphore registers, wherein each core-level hierarchical shared semaphore register is coupled to a different processor core. Each hierarchical shared semaphore register is writable to each of a plurality of streams executing on the coupled processor core. One or more chip-level hierarchical shared semaphore registers are also coupled to plurality of processor cores, each chip-level hierarchical shared semaphore register writable to each of the plurality of processor cores.
