A GPU cache bypassing method and apparatus with the adoption of monolithic 3D based network-on-chip

摘要

The present invention discloses a GPU cache bypass method and apparatus utilizing a NoC structure based on a monolithic 3D integration technology. According to this embodiment, there is provided a type classification structure for tracking the L1 cache utilization rate of individual warps, classifying the types of the individual warps, and determining a threshold value of bypass of the individual warps according to the classified warp types; A request bypass for adaptively determining a bypass for a memory request of the individual warp by comparing a saturation counter (SC) that records the bypass history of the individual warp and a threshold value of the bypass of the individual warp A GPU cache bypass device using a monolithic 3D integration technology-based NoC structure including a monolithic 3D-based NoC (Network on Chip) to which a memory request bypassed by the pass structure and the request bypass structure is input is provided
