High-speed digital accumulator with wide dynamic range
摘要:
A high-speed, wide dynamic range, digital accumulator includes a first adder stage in which an input addend is added to a value of a least significant part of an output of an accumulator from a preceding clock period. The accumulator also includes at least one second stage having incrementer/decrementer means for performing an increment, decrement or identity operation on a most significant part of the output of the accumulator. The incrementer/decrementer means includes logic means for triggering the increment, a decrement or identity operation on the most significant part of the accumulator output based on a decision made on results obtained at the previous clock period.
