More Information
Summary: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 a first microinstruction is split to obtain N sub-requests, and N is a positive integer larger than 1; processing the N sub-requests through a microinstruction processing assembly line; and writing a combined attribute obtained by combining the attributes of the N sub-requests into an address input queue for the prefetcher, so that the prefetcher performs prefetch training based on the combined attribute. 本公开的一些实施例提供了一种处理器的预取训练方法、处理装置、处理器和计算设备。该处理器的预取训练方法，包括：对第一微指令进行拆分以得到N个子请求，其中，N为大于1的正整数；将N个子请求经微指令处理流水线的处理；以及将N个子请求的属性合并后得到的合并属性写入用于预取器的地址输入队列，以使得预取器基于合并属性进行预取训练。
