Title:
DATA PROCESSING METHOD, DECODING CIRCUIT, AND PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2021/120713
Kind Code:
A8
Abstract:
A data processing method, a decoding circuit, and a processor, which belong to the technical field of computers. The method comprises: determining whether an acquired instruction is a compressed instruction (S101); when the acquired instruction is a compressed instruction, acquiring key information in the compressed instruction, the key information comprising an instruction repetition type and the number of times the instruction is repeated (S102), wherein the instruction repetition type is used to indicate an instruction type to be repeated, and the number of times the instruction is repeated is a positive integer greater than or equal to 2; and decompressing the compressed instruction according to the instruction repetition type and the number of times the instruction is repeated so as to decompress the compressed instruction into multiple instructions corresponding to the instruction repetition type and being the same number as the number of times the instruction is repeated (S103). By compressing an instruction, one instruction block can accommodate more three operand instructions, which effectively reduces the probability of instruction cache miss, while also optimizing efficiency.
