BDTI's DSP Dictionary | Berkeley Design Technology, Inc

The following dictionary of DSP terms is provided as a resource to the community. Absolute addressing Alternative term for memory-direct addressing. Accumulator A register used to hold the output of the ALU or multiply-accumulate unit. On fixed-point processors, accumulators are usually at least twice as wide as the processor’s basic word width (in bits) and may be wider. DSP processors typically have from one to four accumulators.
