Abstract

Embodiments of the invention disclose a storage method and a storage device for realizing a RAID5 function, and a main control chip system. The storage method comprises the following steps: acquiring current target data; carrying out exclusive-or operation on the current target data and current exclusive-or data to obtain exclusive-or result data, wherein the current exclusive-or data is the exclusive-or result data of previous target data stored in a data cache storage module; and delaying the exclusive-or result data by a cycle and storing the exclusive-or result data in the data cache storage module to cover the exclusive-or result data of previous target data. According to the method, the exclusive-or result data of all target data is stored in the same data cache storage module, and the current exclusive-or result data covers the exclusive-or result data of previous target data, which can reduce the usage amount of the storage unit and reduce the power consumption of the chip.

Description

technical field [0001] The invention relates to the technical field of computer storage, and more specifically, relates to a storage method, a device and a main control chip system for realizing the RAID5 function. Background technique [0002] The storage unit on the chip system (SOC, System on Chip) accounts for 70% of the entire chip area, and the power consumption accounts for more than 40% of the entire chip, and the traditional RAID5 design requires multiple sets of caches to achieve, for example: if each batch sends The data size of the data is 4kbyte data, and the check digit information generated by XOR operation is stored in the 4kbyte data cache. When the next 4Kbyte data comes, it is read out for XOR operation, and the operation result is stored in another cache. In this way, if there are N pieces of data, N 4Kbyte data caches are required, which greatly occupies the usage of the storage unit and increases the power consumption of the chip. [0003] Therefore, h...
