Abstract
A computer-implemented method includes receiving performing a fused modular multiply and add operation to compute d=((a*b)+c) % p, wherein a, b, and c, are provided as a set of operands. A first multiply-and-accumulate unit computes a binary multiplication to compute a*b. A second multiply-and-accumulate unit computes a first intermediate result by updating a result of the binary multiplication using p. An accumulator of a third multiply-and-accumulate unit is initialized with c. The third multiply-and-accumulate unit computes a second intermediate result using the first intermediate result and c. An adder unit subtracts a portion of the second intermediate result from a portion of the result of the binary multiplication. The output of the adder is provided as a result of the fused modular multiply and add operation.
