Temporary storage processing method, temporary storage program and storage device

Abstract

The invention discloses a temporary memory processing method, a temporary memory program and a storage device. The temporary memory processing method includes: receiving a write command, the write command includes a write data and a write address; judging whether a corresponding temporary storage address corresponding to the write address is in a miss state, to generate a judging result; and decide whether to write the write data into a corresponding buffer address of a buffer memory according to the judging result. Therefore, the present invention can improve processor performance and reduce power consumption.

Description

technical field [0001] The invention relates to a memory processing method, a memory program and a device, in particular to a temporary memory processing method, a temporary memory program and a storage device for processing a temporary memory address miss state. Background technique [0002] When the existing storage device executes writing data or other program instructions, it will first search whether there is matching instruction data in the temporary memory. If yes, write data directly to the temporary storage. Generally speaking, there are mainly write-through and write-back methods for writing data into the temporary memory. [0003] Write-through writes data to the external memory regardless of whether a hit or a miss occurs. The write-back type will not directly write to the external memory when a miss occurs, but will read the data at the address corresponding to the write instruction from the external memory and store it in the corresponding address in the scra...
