Accumulating Arithmetic Memory Integrated Circuit

Reference#: P00447

An accumulating arithmetic memory (AAM) integrated circuit or AAM chip that includes a set of accumulators or registers was developed. Once an accumulator is selected, e.g., by using a look up table, a multiplexer retrieves the data from the selected accumulator. Then, as input data are presented to the AAM chip, an adder adds, subtracts, or multiplies the input data with the data retrieved from the selected accumulator. The resulting output is returned to the originally selected accumulator. The multiplexer can also substitute a zero for the data retrieved from each accumulator, and an internal address counter is used to read out the contents of all accumulators.
