摘要：
A decimal floating-point Fused-Multiply-Add (FMA) unit that performs the operation of ±(A×B)±C on decimal floating-point operands. The decimal floating-point FMA unit executes the multiplication and addition operations compliant with the IEEE 754-2008 standard. Specifically, the decimal floating-point FMA includes a parallel multiplier and injects the addend after required alignment as an additional partial product in the reduction tree used in the parallel multiplier. The decimal floating-point FMA unit may be configured to perform addition-subtraction operations or multiplication operations as standalone operations.
