Abstract
A method for accumulation of information is described. The information is separated into first portions of MSBs and second portions of LSBs. The first and second portions are respectively input to a first adder and a second adder to provide first and second sums. The first and second sums are output from a first and a second storage device for feedback input respectively to the first and second adder to provide the first and second sums. A carry bit output from the second storage device is generated responsive to each wrap condition associated with the storing of the second sums in the second storage device. The carry bit is fed back to the first adder and fed forward for subsequent consolidation with the first sums respectively output from the first storage device. The first sums and the second sums are respectively accumulated as numbers represented in a redundant number system.
