Abstract
A hardware based modulo addressing scheme is described that is fast and makes efficient use of logic. The scheme uses a subtractor, multiplexers and AND/OR logic to produce modulo addresses to address, for example, a circular buffer in a memory. The buffer is defined by the user based on start and end addresses and an offset value. The offset may be positive or negative and may be greater than one.
