Core-to-core start "offload" instruction(s)

Abstract:

Embodiments involving core-to-core offload are detailed herein. For example, a processor core comprising performance monitoring circuitry to monitor performance of the core, an offload phase tracker to maintain status information about at least an availability of a second core to act as a helper core for the first core, decode circuitry to decode an instruction having fields for at least an opcode to indicate a start a task offload operation is to be performed, and execution circuitry to execute the decoded instruction to: cause a transmission an offload start request to at least the second core, the offload start request including one or more of: an identifier of the first core, a location of where the second core can find the task to perform, an identifier of the second core, an instruction pointer from the code that the task is a proper subset of, a requesting core state, and a requesting core state location is described.
