Abstract
An improved method of transferring burst data in a microprocessor is described. The improvement lies in the burst ordering of the data items to be referenced. The original address is selected as the data item that the user initially wants to access. Subsequent addresses in the burst are generated according to a mathematical algorithm. The algorithm generates the remaining addresses as a function of the internal bus width, the external memory/bus line size and the original address. Using the burst sequence of the present invention, memories/buses of different widths can be smoothly coupled to a microprocessor having a fixed CPU bus size (e.g., 32 bits).
