The FMA instruction set is an extension to the 128 and 256-bit Streaming SIMD Extensions instructions in the x86 microprocessor instruction set to perform fused multiply–add (FMA) operations. [1] There are two variants: FMA4 is supported in AMD processors starting with the Bulldozer architecture. FMA4 was performed in hardware before FMA3 was.
The DS2 and DS3 registers (which are specific to the NEC V55) act similar to regular x86 real mode segment registers except that they are left-shifted by 8 rather than 4, enabling access to 16MB of memory. Block transfer instructions, such as MOVBKW, can access the 16MB memory space by simultaneously prefixing with DS2 and DS3.
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
