- Multiplication followed by an addition/subtraction is the common operation in many digital signal and image processing applications. This paper presents a reconfigurable floating-point real/complex fused multiply and add (R/C-FMA) unit using small precision (IEEE-754-2008 16-bit half-precision) format. The developed FMA can be reconfigurable from real to complex based on the control bits. This architecture performs real FMA [( a × b ) + c ], complex FMA {[( a + ib ) × ( c + id )] + ( e + if )} or mixed real and complex FMA {[( a + ib ) × ( c + id )] + e }. The field programmable gate array (FPGA) implementation of R/C-FMA design, utilises the modern features of inbuilt DSP blocks for mantissa multiplication and addition/subtraction. The efficient DSP usage for fp16 FMA design shows a 60% reduction in LUT area when compared to conventional fp32 FMA.
