Zusammenfassung: | The invention provides a cache data reading method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: controlling a memory access instruction to enter a pipeline queue from an initial data bit of the pipeline queue of a second-level cache under the condition of determining that the memory access instruction of a processor is not hit in the first-level cache; obtaining a hit result of the memory access instruction in the second-level cache after the interval of the first number of data bits; if the result is hit, an awakening instruction is immediately generated through the second-level cache and sent out by the awakening queue, after a second number of data bits are spaced, refilling data are obtained through the second-level cache, and the memory access instruction serves as a refilling instruction and is sent out by the refilling queue. The whole process does not need to read the assembly line state and the state of the refilling queue request, and o |
