Abstract
A sequential address generation arrangement (45, 61, 62, 99, 102) generates a sequence of addresses in response to an initial address and disables generation of the sequence of addresses in response to a control signal (LAST NIB) produced from at least a portion of the initial address at the conclusion of generation of a predetermined number of sequential addresses, the predetermined number being decoded from the initial address.
Claims3
An address generation arrangement for generating in an address register (99) a succession of sequential addresses in addressable memory space for accessing operands to be processed by arithmetic logic unit (30) operations, the sequential addresses being generated by means (62) responsive to an initial address stored in the address register and arranged for periodically incrementing the address stored in the address register, the succession of addresses being terminated by means (69, 71, LAST NIB) for disabling the periodic incrementing of the address stored in the address register CHARACTERIZED IN THAT
- a control counter (69) counts operations of the arithmetic logic unit, and
- the disabling means (69, 71, LAST NIB, 458, 455) respond to at least a portion of the initial address (455 and 458) and a count in the control counter of the number of arithmetic logic unit (30) operations for producing a signal (LAST NIB) which terminates the periodic incrementing of the address stored in the address register at the conclusion of the generation of a predetermined number of sequential addresses, the predetermined number being decoded (458) by the disabling means from the portion of the initial address.
