Preemption Techniques for Memory-Backed Registers - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240095176 titled 'Preemption Techniques for Memory-Backed Registers
Simplified Explanation
The patent application abstract describes techniques related to thread preemption in the context of memory-backed registers. In some embodiments, a memory hierarchy includes cache levels and memory circuits. Execution circuitry operates on operands in architectural registers to execute instructions of threads, with data stored and backed by the memory hierarchy. Control circuitry, in response to a context switch indication for a thread, flushes and invalidates a set of architectural register data from a cache level and stores memory page information associated with the set of architectural register data.

Original Abstract Submitted
techniques are disclosed relating to thread preemption in the context of memory-backed registers. in some embodiments, a memory hierarchy includes one or more cache levels and one or more memory circuits. execution circuitry may operate on operands in architectural registers to execute instructions of threads, where data for the architectural registers is stored and backed by the memory hierarchy. control circuitry may, in response to a context switch indication for a given thread: flush and invalidate a set of architectural register data from a first cache level and store memory page information (e.g., a page catalog base address) associated with the set of architectural register data.
