REUSE OF DECODED INSTRUCTIONS

摘要

Systems and methods are disclosed for reusing fetched and decoded instructions in block-based processor architectures. In one example of the disclosed technology, a system includes a plurality of block-based processor cores and an instruction scheduler. A respective core is capable of executing one or more instruction blocks of a program. The instruction scheduler can be configured to identify a given instruction block of the program that is resident on a first processor core of the processor cores and is to be executed again. The instruction scheduler can be configured to adjust a mapping of instruction blocks in flight so that the given instruction block is re-executed on the first processor core without re-fetching the given instruction block.
