GPU MEMORY CONTROL APPARATUS FOR OPTIMIZING GPU MEMORY ACCESS THROUGH PRE-PATCHED SCRATCHPAD MEMORY DATA AND CONTROL METHOD THEREOF

摘要

This disclosure discloses a memory control apparatus and method that can prefetch data that frequently causes forcible loss in an L1 cache in a GPU to a scratch pad memory to reduce an overhead that is increased due to a forced loss of the cache memory. According to the memory control apparatus and method of the present invention, data can be quickly accessed by accessing and caching data. When a large amount of data is read in advance, the bandwidth of the memory of the GPU is fully utilized, The overhead due to the memory delay time can be minimized.
