Problems solved by technology

Usually, the operating frequency of the core (Core) of the CPU is higher than the operating frequency of the memory. Therefore, the CPU needs to wait for hundreds of CPU clock cycles to directly obtain data from the memory, which will cause the CPU to fail because it cannot continue to process related instructions or data. Produces idling, causing performance loss

Abstract

The embodiment of the invention provides a prefetch training method of a processor, a processing device, the processor and computing equipment. The prefetch training method of the processor comprises the steps that according to an instruction translation rule, an instruction is translated to obtain N microinstructions, and N is a positive integer larger than 1; and triggering a prefetcher to perform one or more training operations based on the N microinstructions, and for each training operation in the one or more training operations, the prefetcher performing prefetch training based on parameters of the training operation.

Description

technical field [0001] The technical field of processors in some embodiments of the present disclosure, in particular, relates to a processor prefetch training method, a processing device, a processor, and a computing device. Background technique [0002] In a central processing unit (Central Processing Unit, CPU) architecture, program instructions and data are generally stored in a memory such as a dynamic random access memory (Dynamic Random Access Memory, DRAM). Usually, the operating frequency of the core (Core) of the CPU is higher than the operating frequency of the memory. Therefore, the CPU needs to wait for hundreds of CPU clock cycles to directly obtain data from the memory, which will cause the CPU to fail because it cannot continue to process related instructions or data. Idling occurs, causing performance loss. Therefore, modern high-performance CPUs are usually provided with a multi-level cache (Cache) architecture to store recently accessed data. Furthermore...
