Abstract: Very long instruction word (VLIW) instruction processing using a reduced-width processor is disclosed. In a particular embodiment, a VLIW processor includes a control circuit configured to receive a VLIW packet that includes a first number of instructions and to distribute the instructions to a second number of instruction execution paths. The first number is greater than the second number. The VLIW processor also includes physical registers configured to store results of executing the instructions and a register renaming circuit that is coupled to the control circuit.

Abstract: A system, processor, and method to predict with high accuracy and retain instruction boundaries for previously executed instructions in order to decode variable length instructions is disclosed. In at least one embodiment, a disclosed processor includes an instruction fetch unit, an instruction cache, a boundary byte predictor, and an instruction decoder. In some embodiments, the instruction fetch unit provides an instruction address and the instruction cache produces an instruction tag and instruction cache content corresponding to the instruction address. The instruction decoder, in some embodiments, includes boundary byte logic to determine an instruction boundary in the instruction cache content.

Abstract: In one embodiment, the present invention includes an apparatus having an instruction selector to select an instruction, where the selector is to store a dependent indicator to indicate a direct dependent consumer instruction of a producer instruction, a decode logic coupled to the instruction selector to receive the dependent indicator when the producer instruction is selected and to generate a wakeup signal for the direct dependent consumer instruction, and wakeup logic to receive the wakeup signal and to indicate that the producer instruction has been selected. Other embodiments are described and claimed.
