(Ask a Question)

Normal mode performs a 18-bit addition (pre-adder) and a 19 x 18 multiplication operation as per the following output equation:

P[47:0] = ((B[17:0] ± D[17:0]) x A[17:0]) + C[47:0] + E[47:0] + CARRYIN

The following figure shows the functional block diagram of the Math block in normal mode.
