Abstract
Systems and methods for scheduling instructions using pre-decode data corresponding to each instruction. In one embodiment, a multi-core processor includes a scheduling unit in each core for selecting instructions from two or more threads each scheduling cycle for execution on that particular core. As threads are scheduled for execution on the core, instructions from the threads are fetched into a buffer without being decoded. The pre-decode data is determined by a compiler and is extracted by the scheduling unit during runtime and used to control selection of threads for execution. The pre-decode data may specify a number of scheduling cycles to wait before scheduling the instruction. The pre-decode data may also specify a scheduling priority for the instruction. Once the scheduling unit selects an instruction to issue for execution, a decode unit fully decodes the instruction.
