The Fused Multiply-Add extension is an optional architecture that extends the VFPv3 architecture. It provides VFP instructions that perform multiply and accumulate operations with a single rounding step, so suffers from less loss of accuracy than performing a multiplication followed by an add.

The fused multiply-add instructions are only available on VFP systems that implement the fused multiply-add extension. The VFP system that implements the fused multiply-add extension is VFPv4.
