Architecture Exploration of High-Performance Floating-Point Fused Multiply-Add Units and their Automatic Use in High-Level Synthesis

Abstract: Abstract-Multiply-add operations form a crucial part of many digital signal processing and control engineering applications. Since their performance is crucial for the applicationlevel speed-up, it is worthwhile to explore a wide spectrum of implementations alternatives, trading increased area/energy usage to speed-up units on the critical path of the computation. This paper examines existing solutions and proposes two new architectures for floating-point fused multiply-adds, and also considers the impact of d… Show more

“…Although this architecture [16] can remove the carry propagation in the final adder, it requires a (2N+α-1)-bit accumulator. Besides, it is also noteworthy to mention that the concept of this architecture [16] has been used in modern floating-point fused multiply-add (FMA) designs [17], [18].…”
