Virtual address access to tiled surfaces

摘要: A data accessing system (160) provides access to video display stored in one or more frame buffers (45) via a virtual buffer implemented as phantom port (201). The facilitates remapping between pixel coordinate space and memory address for both tiled linear addressing schemes. Generation of addresses is obtained through shifting, replacing, concatenating operations. These operations can be perform very fast comparison the multiplication, addition, division, modulo used convential processors, controllers central processing units (80). In some embodiments are converted buffer. Alternate use adapted respond directly generated addresses. present invention thus generate efficiently storage capacity
