SYSTEMS, APPARATUSES, AND METHODS FOR DATA SPECULATION EXECUTION

摘要

Systems, methods, and apparatuses for data speculation execution (DSX) are described. In some embodiments, a hardware apparatus for performing DSX comprises a hardware decoder to decode an instruction, the instruction to include an opcode and an operand to store a portion of a fallback address and an operand to store a stride value, execution hardware to execute the decoded instruction to initiate a data speculative execution (DSX) region by activating DSX tracking hardware to track speculative memory accesses and detect ordering violations in the DSX region, and storing the fallback address.

1. An apparatus comprising:
a hardware decoder to decode an instruction, the instruction to include an opcode and an operand to store a portion of a fallback address and a stride value; and execution hardware to execute the decoded instruction to initiate a data speculative execution (DSX) region by activating DSX tracking hardware to track speculative memory accesses and detect ordering violations in the DSX region, and storing the fallback address, wherein the stride value is a number of instructions to have address checks performed on them by the DSX tracking hardware.
