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...

HELP ME WITH TRUE / FALSE and Multiple choices. Fixed-width instructions make it difficult to decode because the number of bytes each instruction is using can change. True False A register is incremented by either a byte or a word to advance to the next element in an array with Indexed Addressing. True False The "la" instruction is an example of a pseudo-instruction. True False PC-relative addressing uses the program counter as the base address. True False PC-relative addressing uses...

Consider a VEX-executing VLIW machine with the following characteristics: The machine supports 4 slots (4-wide machine) with the following resources: 2 memory units each with a load latency of 3 cycles 2 integer-add/sub functional units with a latency of 2 cycle 1 integer-multiply functional unit with a latency of 4 cycles Each functional unit in the machine is pipelined and can be issued a new operation at each cycle. However, the results of an operation are only available after the...

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. Show the IEEE 754 binary representation of the number -7.425 in a single and double 7. If...

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...

Assignment 4 File “quad_sol.s” contains a quadratic polynomial solver, which calculates the integer solution of a quadratic polynomial equation. 1. Rewrite the program using instructions reordering to reduce the number of cycles needed to execute the program. Indicate the number of cycle reduction. 2. Describe how forwarding would affect the execution of the program. CODE # quad_sol.s # This assembly program calculates the integer solutions of a quadratic polynomial. # Inputs : The coefficients a,b,c of the equation a*x^2 +...

Group Project 1 The Micro-1 Processor Simulation <Micro-1 Computer> Here's the organization of a computer equipped with a Micro-1 processor Memory contains an array of integer cells: int cell[] = new int[CAP]; where CAP is the capacity of memory. Initially this is set to 256. Internally, the Micro-1 processor is equipped with eight 32-bit data/address registers and two 32 bit control registers: PC, the program counter, contains the address of the next instruction to execute. IR, the instruction register, contains...
