Memory reference estimation method and device based on improved cache

摘要

A computer system that includes a processor, a memory and a processor cache for the main memory with a check-in-cache instruction may be provided. The processor executes computer readable instructions stored in the memory that include receiving a check-in-cache instruction from a check-in-cache storage location. The instructions also include responsive to receiving the check-in-cache instruction, determining whether data bytes specified by the check-in-cache instruction are at least partially available in the processor cache. The instructions further include storing a condition code of the determination result in a storage location.

1. A computer system comprising:
a memory having computer readable instructions, the memory including a main memory; a processor cache for the main memory; and a processor for executing the computer readable instructions, the computer readable instructions comprising: receiving a check-in-cache instruction from a check-in-cache instruction storage location; and responsive to receiving the check-in-cache instruction, determining whether data bytes specified by the check-in-cache instruction are at least partially available in the processor cache without accessing the processor cache data or loading data to the processor cache, storing a condition code of the determination result in a storage location.
