provision of load address predictions using load path history-based address prediction tables on processor-based systems

摘要

Aspects disclosed in the detailed description include providing load address predictions using load path history-based address prediction tables on processor-based systems. In one aspect, a load address prediction engine provides a load address prediction table containing multiple load address prediction table entries. Each load address prediction table entry includes a predictor tag field and a memory address field for a load statement. The load address prediction engine generates a table index and predictor label based on an identifier and a load path history for a detected load instruction. The table index is used to query a corresponding load address prediction table entry. If the predictor tag matches the payload address prediction table entry predictor label field corresponding to the table index, the memory address field of the load address prediction table entry is provided as an address. expected memory for the load instruction.
