Data processing system and method, and medium

A data processing system, wherein the data processing system comprises a plurality of internal-memory devices and at least one host;

• and
• wherein the at least one host comprises a current host;
• the plurality of internal-memory devices are connected to the at least one host;
• the at least one host comprises a buffer element;
• at least one of the plurality of internal-memory devices stores a buffer-prefetching decision generator;
• and
• the at least one host is configured for:
• after has received an accessing request, in response to having determined that the buffer element of the at least one host does not store target data that the accessing request is to access, by the current host, transmitting the accessing request to the plurality of internal-memory devices, whereby the plurality of internal-memory devices respond to the accessing request, determine pre-buffered data by using the buffer-prefetching decision generator, and transmit the pre-buffered data to the buffer element of the current host to be stored;
• wherein the at least one internal-memory device is configured for:
• inputting the accessing request and physical addresses of the internal-memory devices into the buffer-prefetching decision generator, whereby the buffer-prefetching decision generator outputs a predicted physical address, and determines data stored in the predicted physical address to be the pre-buffered data;
• wherein the at least one internal-memory device is configured for:
• determining a delay time and a historical-reading-time average value that correspond to the predicted physical address, and according to the delay time and the historical-reading-time average value, determining a transmission time sequence of the pre-buffered data.
