Chapter 7, Problem 7.2P

Q4) 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.

Write   hamming code for the data 0011 for the (i) Even parity (ii) Odd parity. Explain the process briefly

1. Assume that the registers are 8-bit wide. Consider the following code: MOV R1, #4A MOV R2, #40 ADD R3, R1, R2 a) What will be the 8-bit result in Register R3 (in hex)? b) What is the 8-bit result in Register R3 (as unsigned decimal)? c) What is the 8-bit result in Register R3 (as signed decimal)? d) What will be the value of the carry (C) bit?

How to build this circuit? (on Digital or Logisim)  Binary-coded decimal is an alternative method of representing integers using binary. In it, each base-10 digit is represented by four bits, thus each nibble takes one of 10 values (0000 through 1001). Therefore, using BCD, 42 (decimal) is represented as 0100 0010 (binary) and 196 (decimal) is represented as 0001 1001 0110 (binary). Create a circuit in Logisim that accepts as input a pair of two-digit integers represented as BCD and outputs their sum in BCD. Any and all Digital components are fair game. You can assume that all inputs will be valid BCD-encoded numbers.

QO dddd Q1 clock Given: • Counter starts at decimal 9 when Q viewed as a 4-bit unsigned number (Q3 most significant bit) What is the decimal value of Q (viewed as a 4-bit unsigned number) after four more clock “ticks"? Answer

4. For the 8-bit word 11010001, calculate the check bits to be stored with it. Suppose when the word is read from memory, the check bits are calculated to be 1101. What is the data word that was read from memory? (showthe procedure)?

Question Vvv For a microprocessor similar to ATmega328p an 8 bit ADC uses a VREF = 3.3 V. When an analog read is executed the return value is 182. What Voltage is present on the input? Enter the value in the box provided in mV. Round to the nearest mV. No units are required .   .Full explain this question and text typing work only     We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line    ..

Give the equivalent value of the phrase IS IMPORTANT in decimal and binary number system so that the computer can understand. NOTE: The equivalent value of A in Decimal (Base 10) is 65 and Space is equivalent to 32.
