ABSTRACT:
A circuit for generating memory addresses for use in a computer system. The circuit includes multiple address register files that are usable to store parameters of multiple addressing sequences. Each address register file includes a base register for storing a base memory address, an accumulator register for storing a current address in the sequence, a displacement register for storing an address displacement to be used in conjunction with the accumulator register to produce the address sequence, an extension register used as an alternative displacement register, a count accumulator register to monitor a count of the address items in the sequence, and a count restore register used to store an original count for use at the end of the sequence. The circuit is responsive to a variety of commands to load and read the registers, and to manipulate them to provide a desired address sequence, which may be a modulo-N sequence useful in a variety of applications, such as accessing a matrix column-by-column when it is stored row-by-row.
