Homework #1 1. Assume that a computer has 100 different instructions. How many bits will be required in each one address instruction (including operation code and direct address)? a) if the address can refer to 1K different locations? 8K? 64K? b) if the address must be one of eight general purpose registers? 2. If the last operation performed on a computer with an 8 bit word was a signed addition in which the operands were "2" and 127", respectively, what would the values of the following flags be? a) Carry, b) Zero, c) Overflow, d) Sign, e) Even parity. 3. Assume an ideal Op-Amp, find an output expression for the output Vo of the amplifier circuit. R, 4. What are the decoded address ranges for the circuits in the Fiare 1?
