Claim One:
1. An integrated arithmetic unit for use in a serial digital network comprising: A. a first summer for signed serial data having a pair of inputs (D1, D2) for external connection and producing an output sum in signed serial format; EQU (D1 + D2) B. four quadrant multiplication logic for signed serial data having a first input coupled to the output of said summer, a second input (X) for external connection, said multiplication logic producing a double precision output product in signed serial format; EQU (D1 + D2) X and C. a second summer for signed serial data having a first input coupled to the output of said multiplication logic, a second input (S1) for external connection, and producing an external output sum (O1) in signed serial format: EQU O1 = [(D1 + D2) X + S1].
