Abstract:
A method of controlling access to a frame buffer storing bit-mapped image data, according to a high-order group of address bits and a low-order group of address bits received from a central processing unit, comprising the steps of:interchanging at least one bit in said high-order group of address bits with at least one bit in said low-order group of address bits, thereby creating a new high-order group of address bits, and a new low-order group of address bits;supplying said new high-order group of address bits to said frame buffer as row address bits, provided said new high-order group of address bits differ from the new high-order group of address bits in a preceding access; andsupplying said new low-order group of address bits to said frame buffer as column address bits.
