Question 4. (continued) (b) Consider a 16-bit binary number stored in AVR registers r15:r14 which the programmer considers to be a two's complement value. (r15 holds the most significant byte, r14 holds the least significant.) Write down a sequence of AVR assembly language instructions which perform each of the following operations The result should end up in r15:r14. Other registers can be used freely if required i) Sets r15:r14 to the constant value-1 (2 marks)...

1) We would like to design a bus system for 32 registers of 16 bits each. How many multiplexers are needed for the design? Select one: 5 16 1 4 32 2) The basic computer can be interrupted while another interrupt is being serviced. Select one: True False 3) If the Opcode bits of an instruction is 111, then the basic computer instruction type is either memory-reference or input-output. Select one: True False 4) The content of AC in the...

Exercise 1 (9 pts) We have seen that ARM has 16*32 bits registers (plus floating point registers) There is also a status register: CPSR. It contains, among other things, the following important status bits N Negative, set when the result of an arithmetic operation is negative (according to the two's complement encoding of the natural numbers . Z- Zero, set when the result of an operation is zero . C Carry, set when an operation results in a carry bit...

Implement the following statements using MS430 assembly instructions. You may use more than one, but you should minimize the number of instructions required. You can use both native and emulated instructions. Use hex notation for all numbers 1. (a) Move the word located in register R14 to R15 (b) Increment the word in R6 by 2. (c) Perform a bitwise ANDing of the word located at address 0x0240 with the datum in R15, placing the results in R15. (d) Rotate...

In C programming, write a simple program to
take a text file as input and encrypt/decrypt it by reading the
text bit by bit, and swap the bits if it is specified by the first
line of the text file to do so (will explain below, and please let
