Arm Assembly Questions And Answers

ARM Assembly Questions And Answers 1 / 37 What is the main differ- ence between Intel and ARM processor What do ARM instructions only operate on What is the model used by ARM for memory access If we were to increment a 32-bit value at a particu- lar memory address, how many types of instructions would we need The instruction set. Intel is a CISC (complex in- struction set computing) processor - ARM is a RISC (reduced), more general purpose registers Registers Load/Store 3 - ARM uses load/store memory model, so uses load, increment and store. First load value at particu- lar address into a register, increment it within the reg- ister, and store it back to the memory address from the register. Instruction execution is quicker (fewer clock cycles per instruction).
