- By using the design procedure for digital computers, design the following:i. Encoderii. Decoderiii. 4-bit comparatorplease show work included 4. If a 6-bit binary number is used to represent an analog value in the range from -63 to 126, what is the accuracy of the system? In other words, if the binary number is incremented by one, how much change does it represent in the analog value?6) Write an 8086 assembly language program to multiply the contents of the registers CL & BL by using repeated addition and store the result in AX. 0006
- The upper 16 -bit binary count value are displayed on the four seven -segemnt displays as four hexadecimal digits. Hexadecimal values aren't good for human perception. How would you suggest the counter design be modified so that only decimal count values are displayed.ehcu.org/pluginfile 100% 10 / 11 locations, count how many times is 0 and how many times 1 is. Questions:- 1- Write a program in assembly language to perform the following logic ci BL CL DL [5100]- 2- How we can perform the NEG and NOT instructions by using different instructions. 3- Write the following program by using different instruction or instructions for each instruction on the program. MOV AL , 00 MOV BX , FFFF XOR CL , FF NEG BYTE PTR [DI] AND CX , LG- The stack memory is addressed by a combination of the plus offset. The PUSH and POP instructions always transfer between segment -bit number the stack and a register or memory location in the 8086 microprocessors. For string instructions, DI always addresses data in the segment. The 8086 LOOP instruction decrements register for a 0 to decide if a jump occurs and tests it
- bit numbers and store lower byte of the result in accumulator A and higher byte in accumulator B.. Similarly lower byte of 2nd number is stored in R2 and higher byte in R3. Now subtract these two 16 numbers in the RAM such that lower byte of 1t number is stored in R0 and higher byte in RI. manipulate 16 bits numbers as well. Write an assembly language program that stores two 16 bits 8051 is an 8-bit microcontroller that performs arithmetic on 8-bit numbers. However, we can Question#3: 8051 is an 8-bit microcontroller that performs arithmetic on 8-bit numbers. HoweveQ4) Design a Register File which includes four 2-bit registers (In total, it includes 8 bits). Each register is named as ala0, b1b0, c2c0, d1d0. Registers are loaded from the S input. In addition to that, there are two input signals, X and Y, to determine which register to select (ie. 00 selectsfirst register ala0 etc). Also there is R signal. When W is zero, the content of the register does not change. When the W is 1 the selected register is loaded with a new value by shifting from the S input. Design this register file by using D flip-flops.1. Write the contents of all registers and the conditions codes registers after each execution instructions in Table Q1(a).
