Abstract: Implementations of using tiles for caching are detailed In some implementations, an instruction execution circuitry executes one or more instructions, a register state cache coupled to the instruction execution circuitry holds thread register state in a plurality of registers, and backing storage pointer storage stores a backing storage pointer, wherein the backing storage pointer is to reference a state backing storage area in external memory to store the thread register state stored in the register state cache.

Abstract: Embodiments of an invention related to compacted context state management are disclosed. In one embodiment, a processor includes instruction hardware and state management logic. The instruction hardware is to receive a first save instruction and a second save instruction. The state management logic is to, in response to the first save instruction, save context state in an un-compacted format in a first save area. The state management logic is also to, in response to the second save instruction, save a compaction mask and context state in a compacted format in a second save area and set a compacted-save indicator in the second save area. The state management logic is also to, in response to a single restore instruction, determine, based on the compacted-save indicator, whether to restore context from the un-compacted format in the first save area or from the compacted format in the second save area.
