Abstract
Methods, systems or apparatus and computer program products are provided that interface between two data buses operating at different speeds. Such interfaces utilize a buffer which has an apparent size larger than the physical size of the buffer to receive blocks of data which are larger than the size of the buffer. The apparent size of the buffer is created by simultaneously writing data to and reading data from the buffer such that the same storage locations may be used more than once to hold the data. The present invention may be utilized for receiving data from either the high speed or the lower speed bus.
