Question

Demonstrate the multiplication of two binary numbers

Answer 1

Explanation:

Binary multiplication can be achieved by using a ROM as a look-up’ table. For example, multiplication of two 4-bit numbers requires a ROM having eight address lines, four of them, X4X3X2X1 being allocated to the multiplier, and the remaining four, Y4Y3Y2Y1 to the multiplicand. Since the multiplication of two 4-bit numbers can result in a double-length product, the ROM should have eight output lines, and a ROM with a capacity of 256 bytes is required.
