A) A limited binary divider can be built in a ROM by looking up the answer for every division combination of a pair of numbers. The inputs here are two 6 bit numbers. The outputs are a 6 bit quotient and a 6 bit remainder. What size ROM (in a decimal number; not in 2^n notation) is required for such a ROM divider of two 6 bit numbers?

Answer: ______ words X _____ bits

B) The ROM divider from part A has a flaw: how to indicate division by zero. A signal "divby0" must be output indicating the error. Identify two different methods to generate this error signal (equations or narrative).

Answer: Method #1: _____________________________________

Method #2: _____________________________________
