A method and device for data processing

Abstract

An embodiment of the invention provides a data processing method and device and relates to the field of data processing. The data processing method aims at improving data processing efficiency of the data processing device and reducing power consumption in the data processing process. The method comprises the steps of enabling the data processing device to read data in a register and acquire state information of the register, and processing the data if determining that the register does not cache the data according to the state information of the register; if determining that the register caches the data according to the state information of the register, caching the data, and processing the data. The data processing method and device are used for data processing.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data processing method and device. Background technique [0002] At present, general-purpose data processing equipment uses a register file architecture to store the intermediate results of the instruction execution process and the operating status of the data processing equipment, which is an important part of the data processing equipment architecture. [0003] The register file cache technology has increasingly become an important register file design technology. In the existing register file cache technology, the architecture of the register file is generally composed of the register file cache and the main register file. The main register file includes multiple registers. Among them, The register file cache caches the data of the recently frequently used registers, and the main register file stores the data of all registers. When the data processing device reads the ...

[0004] However, since most of the data in the register value is invalid after being used once, after an access miss occurs in the register file cache, the read data in the main register file will never be used again after being cached, making the cache The data in the cache is invalid, and because the cached data will replace the original useful data in the register file cache, the efficiency of the register file cache will be reduced, and the efficiency of data processing equipment for data processing will be reduced. The data cache increases the power consumption of the data processing equipment, therefore, when the above-mentioned invalid data is cached, the power consumption of the data processing equipment will be wasted
