Abstract: An accumulation apparatus, which adds a number of data values, has an adder and an asynchronous ripple counter. The adder adds each current data value to an adder sum of the preceding data values. The asynchronous ripple counter, which is coupled to the adder, generates a ripple count by counting occurrences of overflow of the adder. The accumulation apparatus outputs an accumulated data value having the adder sum as least significant part and the ripple count as most significant part.

Abstract: An accumulation apparatus (230) for accumulating a number of data values comprises an adder (275) arranged, for each of the number of data values in turn, to add the data value to an adder sum present at an output (278) of the adder (275) for the preceding one of the data values. An asynchronous ripple counter (240) is coupled to the adder (275) for generating a ripple count by counting occurrences of overflow of the adder (275). The accumulation apparatus (230) provides an accumulated data value having the adder sum as its least significant part and the ripple count as its most significant part.
