Multiply-accumulate
The multiply-accumulate operation computes a product and adds it to an accumulator.
- a = a + b×c
When done with integers this operation is typically exact (computed modulo some power of 2).
When done with floating point numbers it might be performed with two roundings (typical in many DSPs) or with a single rounding, called a fused multiply-add (FMA).
