Abstract

See full text

A microprocessor a plurality of processing cores, wherein each of the plurality of processing cores instantiates a respective architecturally-visible storage resource. A first core of the plurality of processing cores is configured to encounter an architectural instruction that instructs the first core to update the respective architecturally-visible storage resource of the first core with a value specified by the architectural instruction. The first core is further configured to, in response to encountering the architectural instruction, provide the value to each of the other of the plurality of processing cores and update the respective architecturally-visible storage resource of the first core with the value. Each core of the plurality of processing cores other than the first core is configured to update the respective architecturally-visible storage resource of the core with the value provided by the first core without encountering the architectural instruction.
