摘要: A circuit controls the reordering of data as it is transferred to control a memory. The be reordered presented such that ordinate bit position within word uniquely associated with particular input bus. bus inputs, however, are connected VRAM in an arrangement contrary desired association compressed word. single swizzle logic operates allow graphic for presentation block-write inputs regardless or pixel size. relies upon properly expanding prior actual positions bits. method controlling also described.
