    摘要: A device and methods are provided for accessing memory. In one embodiment, a method includes receiving a request for data stored in a device, checking a local memory for data based on the request to determine if one or more blocks of data associated with the request are stored in the local memory, and generating a memory access request for one or more blocks of data stored in a memory of the device based when one or more blocks of data are not stored in the local memory. In one embodiment, data stored in memory of the device may be arranged in a configuration to include a plurality of memory access units each having adjacent lines of pixel data to define a single line of memory within the memory access units. Memory access units may be configured based on memory type and may reduce the number of undesired pixels read.
