Abstract
A memory interface ( ) and method of use implements a cache ( ) bursting addressing technique which begins a read of main memory ( ) in a wrap around mode before automatically switching into a linear addressing mode. The use of two modes which automatically change eliminates an access delay to the main memory when switching modes and optimizes system performance by providing a most critical word first in a first cache line fill and advancing to a sequential address following the first cache line. The sequential address has a higher probability of next use by the processor than any other address. The automatic mode change may be overridden by the memory interface.
