The application discloses a data access method, device and computer-readable storage medium for a board chip. Among them, the method is applied to the board chip with built-in DDR and high-bandwidth memory; the execution method of the board chip is as follows: when receiving the data access request issued by the host, if it is determined that the data to be accessed is stored in the target data block of the DDR, Then update the accessed frequency of each data block of the high-bandwidth memory, and utilize the target data block in the DDR and a plurality of adjacent data blocks to replace the data blocks whose accessed frequency is lower than the preset frequency threshold in the high-bandwidth memory; If the stored data is stored in the high-bandwidth memory, data access is performed in the high-bandwidth memory, and the access frequency of each data block is updated. This application supports high concurrent random access to data, which greatly reduces the time of random access to data and improves the efficiency of data access on board chips.
Description
technical field [0001] The present application relates to the technical field of data reading, in particular to a data access method, device and computer-readable storage medium for board chips. Background technique [0002] With the rapid development of board chips, such as FPGA boards (Field-Programmable Gate Array, Field-Programmable Gate Array) and GPU boards (Graphics Processing Unit, Graphics Processing Unit), users require fast transmission of information, that is, bandwidth requirements The requirements are also constantly increasing. [0003] Relevant board technologies usually access data from DDR data blocks directly based on burst transmission. However, due to the extremely limited bit width of DDR, the number of simultaneous random accesses that can be supported is very small, resulting in the efficiency of accessing data. very low. DDR (Double Data Rate, double rate) has gradually been unable to meet people's needs for bandwidth, and technology development ha...
