Data Storage Method, Storage Apparatus, and Computing Device

摘要

A data storage method, a storage apparatus and a computing device are disclosed. The method includes receiving a presetting command sent by a CPU, where the presetting command instructs to write 1 to a location, which corresponds to a cache line, in memory; writing, according to the presetting command, 1 to the location, which corresponds to the cache line, in the memory; receiving a write command sent by the CPU of writing data in the cache line to the memory; and writing, according to the write command, data 0 in the cache line to a location, which corresponds to the data 0, in the memory.

主权项

1. A data storage method applied in a computing device including a memory controller and a processor coupled to the memory controller, the method comprising:
receiving, by the memory controller, a first presetting command sent by the processor to instruct the memory controller to write 1 to a first location, which corresponds to a first cache line, in a memory of the computing device; writing, by the memory controller according to the first presetting command, 1 to the first location, which corresponds to the first cache line, in the memory; receiving, by the memory controller, a first write command sent by the processor for instructing the memory controller to write a first data in the first cache line to the memory; and writing, by the memory controller according to the first write command, data 0 in the first cache line to a second location, which corresponds to the data 0 in the first cache line, in the memory.
