6 Problem 4 (2 Points)Perform binary arithmetic for the following pairs of 2’s complement numbers and specify whether or not there is an overflow. Illustrate your answer by converting the operands and result to decimal. Assume the result has the same number of bits as the operands.a110+ 110------b0111- 1001-------Problem 5 (3 Points)Suppose we have two operands X and Y, where X = 0x57 and Y = 0xBC. aConvert X and Y into binary. (1 Point) bWhat is the result of X AND Y? Give your answer in hexadecimal. (1 Point)cWhat is the result of X OR Y? Give your answer in hexadecimal. (1 Point)
7 Problem 6 (2 Points)Show the result of performing the following bitwise logic operations:a(NOT(0101)) AND (0101 OR 1010) bNOT(11011 OR (01010 AND 10010)) Problem 7 (1 Point)What is the difference between an instruction set architecture (ISA) and a microarchitecture?Give your answer in onesentence.Problem 8 (2 Points)Suppose we have two 4-bit 2's complement integers 0010 and 1100. Express their sum as an 8-bit 2's complement number.
