SLM display data address mapping for four bank frame buffer |
摘要 |
A method of addressing double buffered memory for an SLM, the memory address having only two bank bits. It is assumed that the pixel data is formatted into bit-planes, such that pixel positions in each bit plane can be identified. A bit plane bit is mapped to a first bank bit, and a pixel position bit is mapped to a second bank bit. The read/write bit is mapped to a column address bit. The remaining bit plane and pixel position bits are mapped to row address and column address bits.
