MAC is defined as Multiplier/Accumulator frequently. In computing, especially digital signal processing, the multiply–accumulate operation is a common step that computes the product of two numbers and adds that product to an hardware unit that performs the operation is known as a multiplier–accumulator (MAC, or MAC unit); the operation itself is also often called a MAC or a MAC operation.

The programmable systolic chip (PSC) is a high performance, special-purpose, single-chip microprocessor intended to be used in groups of tens or hundreds for the efficient implementation of a broad variety of systolic arrays.

For implementing these systolic arrays, the PSC is expected to be at least an order of magnitude more efticient than conventional microprocessors, llie Cited by:   "The Multiplier Accumulator IP core product is a parallel multiplier accumulator module that performs fixed or programmable-length accumulations.

The time taken for the NOT gate‟s output to become “0″ after the application of logic “1″ to the NOT gate‟s input is the propagation delay here. Similarly the carry propagation delay is the time elapsed between the application of the carry in signal and the occurrence of the carry out (Cout) signal.

In a computer's central processing unit (), the accumulator is a register in which intermediate arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read right back again for use in the next operation.
