Answer to Question #245244 in Electrical Engineering for anshu

Question

The 8-bit registers AR, BR, CR, and DR initially have the following values: AR= 11110010, BR= 10110111, CR= 10101001 , DR= 10001000 Determine the 8-bit values in each register after the execution of the following sequence of microoperations. AR <-AR + BR CR <- CR ^ DR, BR <- BR + 1 AR <-AR – CR

Answer 1

AR <- AR + BR

CR <- CR AND DR

BR <- BR + 1

AR <- AR - CR

8-bit values in each register after the execution of a sequence of operations are

AR = 00101001

BR = 0000000

CR = 10101000

DR = 10101010
