# Multiply And Shift And Add

## Fastest MAC algorithm

Fact - one of the most important hardware blocks in DSP cores is the MAC (multiply accumulate) unit. Assumption - the simple "shift and add" algorithm is too slow and therefore isn't utilized. Question - what is the most common algorithm used today for implementing modern (...)

## Multiplying Matrices in VHDL - Need to be able to shift rows

Hi, I am working on a school project. I need to be able to multiply two matrices together. The values in the matrices are all signed digits. I need to multiply two matrices like this and add each value to an offset of : X X X = *

## unconditional block floating point in fft

hi, fft operation is basically a repetitive multiply and add operation.There are certain stages depending on the length of the input vector. In the computation of each stage,one bit is increased in the resulting data. In the fix point calculation, this will overflow the data registers. To avoid this overflow of data (...)
