Abstract: Techniques are disclosed relating to circuitry configured to perform floating-point operations such as fused multiply-addition (FMA) with multiple paths and power control. In some embodiments, an FMA unit includes a near path and multiple far paths and is configured to select a path based on a determined exponent difference. In some embodiments, the FMA unit is configured to operate portions of non-selected paths in a low power state.
