ARM is a 32-bit reduced instruction set computing (RISC) architecture developed in 1985. It features a load/store architecture, uniform instruction length, and conditional execution of instructions based on status flags. ARM processors operate in different modes like user, system, and interrupt modes. Newer ARM features include more control over arithmetic logic unit and shifter operations, auto-increment/decrement addressing, and conditional execution of instructions.

This document summarizes research on estimating the conditions required to break lock in a missile-borne monopulse receiver. It describes designing a third-order phase-locked loop (PLL) receiver model and simulating two jamming scenarios: 1) continuous wave (CW) radar echo with CW jammer signal, and 2) CW radar echo with frequency-modulated (FM) CW jammer signal. For the first scenario, simulation results show the PLL loses lock to the radar echo when the jammer to signal amplitude ratio exceeds 1.01. For the second scenario, simulations estimate the FM modulation index required for break lock varies exponentially with the modulating signal voltage, and an empirical relationship is derived.

We discussed how the processor routes data between internal components in the Chip. Using simple Register Transfer Language notation (t0: dest leftarrow source), show how the following instruction would be processed if we have the indicated transfer registers in the route the signals will take. (The instruction has been decoded and IR2 has the needed address of variable1.) IR2 - instruction register holding the address MAR - memory address register MDR - memory data register REGn - internal register (in control unit) Here is the instruction: mov r12, [variable 1]
Solution
The Register Transfer Language
RTL is a simple, human-oriented language to specify the operations, register communication and timing of the steps that take place within a CPU to carry out higher level (user programmable) instructions.
The operand : MOV
Description : The move the input operand at a register to the second by a word copy
The operations are in data movement
MOV
MVN
Examples:
MOV ro, r1
MOVS r2, #10
NVNEQ r1, #0
Now we have to processed the following register transfer language instruction
MOV r12, [variable1]
That variable may be register for example: R2, R0, R5, etc…..
The some example for MOV R12
MOV R12, R4 = R4 rotated the value
MOV R12, R0, LSL#2 = Shift R0 left by 2
