ABSTRACT:
A configurable arithmetic block for implementing arithmetic functions in a device having programmable logic is described. The configurable arithmetic block comprises a first plurality of registers coupled to receive input data; a second plurality of registers coupled to receive input data; an arithmetic function circuit having a plurality of arithmetic function elements, each arithmetic function element coupled to at least one other arithmetic function element of the plurality of arithmetic function elements and coupled to receive outputs of at least one of the first plurality of input registers and the second plurality of input registers; and an output coupled to the arithmetic function circuit. A method of implementing a configurable arithmetic block in a device having programmable logic is also disclosed.
