Abstract
A data processing system includes a memory device; buffer entries each including a plurality of slabs; a prefetch circuit configured to prefetch data from the memory device and store the data in the buffer entries; and processing circuits respectively corresponding to the slabs, each processing circuit being configured to sequentially demand-fetch and process data stored in corresponding slabs in the buffer entries, wherein each processing circuit checks, when demand-fetching data from a first slab among corresponding slabs, a prefetch trigger bit of a first buffer entry in which the first slab is included, determines, when it is determined that the prefetch trigger bit is set, whether all data stored in the slabs included in a second buffer entry is demand-fetched, and triggers, when it is determined that all the data is demand-fetched, the prefetch circuit to perform prefetch of subsequent data to the second buffer entry.
