Embodiment Construction

[0033] An embodiment of the present invention provides a data storage method, the method comprising: obtaining the start storage address of the previous data block of the current data block to be written; subtracting the start storage address of the current data block to be written size, to obtain an intermediate result; if the intermediate result is less than 0, then map the intermediate result into the effective address of the memory, and use the result of the mapping as the initial storage address of the current data block to be written; If the intermediate result is greater than or equal to 0, then directly use the intermediate result as the initial storage address of the current data block to be written; start from the storage unit corresponding to the initial storage address of the current data block to be written Write the data block currently to be written. The method of the invention can be used in applications such as mp3 decoding and filtering.

Abstract

The invention discloses a data storage method and a device. The method comprises the following steps of: obtaining an initial storage address of a previous data block of the current data block to be written; subtracting the size of the current data block to be written from the initial storage address and obtaining an intermediate result; if the intermediate result is less than 0, mapping the intermediate result into an effective address of a memory and taking the mapped result as the initial storage address of the current data block to be written; if the intermediate result is more than or equal to 0, directly taking the intermediate result as the initial storage address of the current data block to be written; and starting to write in the current data block to be written from a storage unit corresponding to the initial storage address of the current data block to be written. The method provided by the embodiment of the invention can reduce read-write times to the memory, thus reducing the power consumption when writing data in the memory.

Description

technical field [0001] The invention relates to the field of electrical data processing, in particular to a data storage method and device. Background technique [0002] Memory (Memory) is a memory device used to store programs and data. All information in the device using the memory, including the input raw data, program, intermediate operation results and final operation results, etc. are stored in the memory. It deposits and retrieves information according to the location specified by the controller. [0003] With the memory device, there is a memory function to ensure normal operation. Memory can be divided into main memory (internal memory) and auxiliary memory (external memory) according to its purpose. External storage is usually magnetic media or optical discs, which can store information for a long time. Memory refers to the storage component on the motherboard, which is used to store data and programs currently being executed, but it is only used to store progr...
