DATA READING METHOD AND DDR CONTROLLER

摘要

Provided are a data reading method and DDR controller. The method comprises: reading a first data corresponding to a first reading request from the DDR and continuing to read the adjacent data with an address neighboring to the address of the first data after receiving the first reading request sent by a central processing unit, the sum of the data volume of the first data and the adjacent data is the cache line capacity of the central processing unit; caching the adjacent data; reading a subsequent reading request of the adjacent data according to the received request, and sending the cached adjacent data to the central processing unit. The technical solution, relating to the field of computer, is mainly applied to computer systems, and capable of reducing the time required for a central processing unit to obtain the data of a complete cache line and improving the data processing efficiency of a computer system.
