The invention discloses an instruction calling method and device, a processing device and a storage medium. The instruction calling method comprises the step of caching at least two pieces of prediction information in a branch instruction prediction information queue, wherein the at least two pieces of prediction information comprise first prediction information and second prediction information; in response to starting the first mode, generating a first microinstruction group based on the first prediction information, sending the first microinstruction group to the i microinstruction queue selected from the N microinstruction queues for distribution, and sending the first microinstruction group to the microinstruction buffer and caching the first microinstruction group in the microinstruction buffer; in response to starting of the second mode, sending second prediction information to the jth microinstruction processing module selected from the N parallel microinstruction processing modules; and obtaining a second microinstruction group corresponding to the second prediction information from the microinstruction buffer, and sending the second microinstruction group to the jth microinstruction queue in the N microinstruction queues for distribution, N being an integer greater than 1, and i and j being positive integers less than or equal to N.
Description
technical field [0001] The invention relates to a method and device for calling instructions, a processing device and a storage medium. Background technique [0002] The structure of the central processing unit can be divided into a front-end architecture and a back-end architecture. The front end of the processor mainly includes modules for calling instructions, such as Branch Predict, Instruction Fetch, and Instruction Decode. The processor backend mainly includes modules for executing instructions. In order to increase the operating speed of the processor, the processor front end should provide more instructions to the processor back end as soon as possible for execution. Contents of the invention [0003] Embodiments of the present invention provide a method and device for invoking instructions, a processing device and a storage medium, so as to solve the technical problem of low parallelism in invoking instructions in the prior art. [0004] At least one aspect of ...
