ARM Architecture Question & Answers October 11, 2021 By WatElectronics This article lists 100 ARM Architecture MCQs for Engineering Students. All the ARM Architecture Questions & Answers given below includes solution and link wherever possible to the relevant topic. The ARM processor is one of the families of CPUs, which is based on the RISC architecture. The CPU can have two types of architecture they are RISC and CISC architecture. In RISC architectures the number of instructions involves is less and the instructions are also very simple, whereas in CISC architectures the number of instructions involves is more and the instructions are also very complex. The standard form of ARM is Advanced RISC Machine, it has three instruction sets they are 32-bit ARM, 16-bit Thumb, and 8-bit Jazelle instruction set. It has 37 registers, 1 is a dedicated program counter, 1 is a current program status register, 5 saved program status registers, and 30 are general-purpose registers, and has seven basic operating modes they are user, FIQ, IRQ, supervisor, un-def, and system. When the processor is executing in ARM state, then all instructions are 32-bits wide. The ARM has two arithmetic shift operators they are arithmetic shift right and arithmetic shift left. The load instructions are categorized into three types they are multiple register transfer, single register transfer, and swap. The FIQ, IRQ, SVC, USR, ABT, UND are the hardware stacks in ARM7/9. The ARM and thumb instruction set and java byte codes are Jazelle instruction sets. The ARM MMU architecture translates virtual addresses into physical addresses and controls the memory access permissions function. The ARM instruction set architecture is divided into six classes of instructions they are data processing, branch, status register transfer, load & store, co-processor, and exception generating instructions. The RISC, ISA optimization, application-specific components are the power-saving techniques for ARM CPUs. The load and store, data processing, branch, and coprocessor are the ARM instruction sets. 1). What is the standard form of ARM?
