STORE NULLIFICATION IN THE TARGET FIELD

摘要

Apparatus and methods are disclosed for nullifying memory store instructions identified in a target field of a nullification instruction. In some examples of the disclosed technology, an apparatus can include memory and one or more block-based processor cores configured to fetch and execute a plurality of instruction blocks. One of the cores can include a control unit configured, based at least in part on receiving a nullification instruction, to obtain an instruction identification for a memory access instruction of a plurality of memory access instructions, based on a target field of the nullification instruction. The memory access instruction associated with the instruction identification is nullified. The memory access instruction is in a first instruction block of the plurality of instruction blocks. Based on the nullified memory access instruction, a subsequent memory access instruction from the first instruction block is executed.

主权项

1. An apparatus comprising a block-based processor, the block-based processor comprising:
one or more processing cores configured to fetch and execute a plurality of instruction blocks; and a control unit configured, based at least in part on receiving a nullification instruction, to:
obtain an instruction identification for a memory access instruction of a plurality of memory access instructions, based on a target field of the nullification instruction;nullify the memory access instruction associated with the instruction identification, wherein the memory access instruction is in a first instruction block of the plurality of instruction blocks; andbased on the nullified memory access instruction, execute a subsequent memory access instruction from the first instruction block.
