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...

Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. How many bits can be used for the memory address? Question 21 5 pts Suppose we have...

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...

Consider a 64-bit computer with a simplified memory hierarchy. This hierarchy contains a single cache and an unbounded backing memory. The cache has the following characteristics: • Direct-Mapped, Write-through, Write allocate. • Cache blocks are 4 words each. • The cache has 256 sets. (a) Calculate the cache’s size in bytes. (b) Consider the following code fragment in the C programming language to be run on the described computer. Assume that: program instructions are not stored in cache, arrays are...

The sum of the two 32 bit integers may not be representable in 32 bits. In this case, we say that an overflow has occurred. Write MIPS instructions that adds two numbers stored in registers Ss1 and Ss2, stores the sum in register $s3, and sets register Sto to 1 if an overflow occurs and to 0 otherwise. 5. (16pts) 6.
