Abstract

The invention discloses a method for storing a plurality of data in SDRAM, which comprises the following steps: each part of data is divided into a plurality of data blocks with the same size, the size of each data block is equal to the length of BURST which is used for reading the SDRAM internal storage data, and the data blocks of adjacent presetting part date are sequentially staggered and stored into a storing unit of an SDRAM storing array. In the method, the storing positions of the storing data in the SDRAM are arrayed, so the storage data in a SOC system which has larger probability of the concurrent access of a plurality of data packets by the similar offset in each MASTER can be more effectively accessed to save reading time, consequently, the access bandwidth of the SDRAM is increased, therefore, the performance of the whole system is improved.

Description

technical field

[0001] The present invention relates to a method for storing data in SDRAM, especially a method for storing several picture data therein. Background technique

[0002] With the development and wide application of information technology, the use of SDRAM for data storage and reading is becoming more and more widespread.

[0003] Such as figure 1 As shown, currently, in the SOC (system on chip) system design where each MASTER has a relatively high probability of concurrent access to multiple blocks of data packets with similar offsets, there is no requirement for the storage location of the stored data in SDRAM . Such as figure 2 As shown, the storage method of these data in SDRAM is sequential storage, that is, after one data is stored, the next data is stored until all the data are stored. Assuming that the burst length of the data read is 4word, then the data read method please refer to image 3 shown. Since the way data is stored does not correspond ...
