Ones complement = Inverting all the bits in binary Twos complement = Ones complement + 1 48 in binary is = 00110000 Twos complement of -48 is = 11010000 80 in binary is = 01010000 Twos complement of -80 is = 10110000 So, -48 - 80 is 11010000 10110000 ----------- 10000000 ----------- As the MSB is 1. We can say that the answer is negative. and Overflow = 1

(5 points) Convert the following decimal numbers to 8-bit two's complement binary numbers and carry out the additions in binary. Indicate whether the sum overflows the 8-bit result. If not show the result as a decimal number. a) 39 + (-78) b) -43 + (-92)
For problems 8, 9 and 10, convert the following decimal numbers into 8‑bit binary numbers as required for 2's complement math, and perform the indicated operations. Circle or bold your binary answer and show your work. Notes: Remember that positive numbers are represented in sign-magnitude format in 2's complement math 8. +26 +15 = 9. +26 - 15 = 10. - 26 +15 =

4) This exercise will first present the modified algorithm for computing the product of two numbers represented in twos complement with an illustrated example and then ask you to repeat for a different number pair The hardware and the flowchart for signed multiplication in twos complement representation of binary numbers will be slightly modified as follows. Use the version of the unsigned multiplication hardware which employs one double-sized register to hold the partial product and the multiplier a. When shifting...

PROBLEM STATEMENT The mini-calculator will use a small ALU to perform arithmetic operations on two 4-bit values which are set using switches. The ALU operations described below are implemented with an Adder/Subtractor component. A pushbutton input allows the current arithmetic result to be saved. An upgraded mini-calculator allows the saved value to be used in place of B as one of the operands. The small ALU that you will design will use the 4-bit adder myadder4 to do several possible...
