To multiply two numbers by hand takes a few steps but it's something we're taught in school. When dealing with big numbers, really big numbers, we need to a quicker way to do things.

The classical Multiply and Accumulate (MAC) architecture represents the best solution for the implementation of many general purpose algorithms. This structure is found in DSPs, and also in some ...

So to draw an analogy, the very first FPGAs just had LUTs. There were no MACs. And at some point in time, somebody realized that a lot of their customers were using FPGAs for signal processing, doing ...
