Abstract: An operating method of a graphics processing unit includes: receiving a first read request for texels, detecting whether decompression data associated with each of the texels are present in a first cache, decompressing part of a first texture compression block associated with a first texel among the texels when a result of the detecting indicates decompression data for the first texel is not present in the first cache, to generate first decompression data, and generating first texture data corresponding to the first read request, based on the first decompression data and second decompression present in the first cache.

Abstract: A storage device includes a nonvolatile memory device and a storage controller. The storage controller includes a multi-protocol host interface circuit that receives a first-type request including a first logical address from an external host and transmits/receives data corresponding to the first-type request with the external host by a block unit. Additionally, the multi-protocol host interface circuit receives a second-type request including a first physical address from the external host and transmits/receives data corresponding to the second-type request with the external host by a unit smaller than the block unit. A mapping cache manager manages an address translation table cache, sends an address translation request including the first physical address to the external host, and receives a response including mapping information corresponding to the first physical address from the external host.
