The first pipe features a 4-cycle [[FMAC]] and a 3-cycle multiplier while the second pipe incorporates a 2-cycle [[floating-point adder]]. In all three units, Samsung reduced the latency by one cycle (from 5, 4, and 3 cycle latencies respectively). Overall, all three pipes are fuller and more capable. All three pipes have an FMAC and FADD units, doubling the [[FLOPS]] of the prior design. Additionally, there is a second pipe with a [[cryptography]] floating point conversion unit. Similar to the integer [[divider]] unit, the M3 also implements a radix 16 (4 bits/cycle) for the FDIV unit, halving the latency in the iterative portion from the prior generation which implemented a radix 4 (2 bits/cycle). | The first pipe features a 4-cycle [[FMAC]] and a 3-cycle multiplier while the second pipe incorporates a 2-cycle [[floating-point adder]].
