The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by Arm Holdings.These cores are optimized for low-cost and energy-efficient microcontrollers, which have been embedded in tens of billions of consumer devices. ARM programmer model • The state of an ARM system is determined by the content of visible registers and memory. Instruction Set Architecture ⢠Describes how processor processes instructions ⢠Makes available instructions, binary codes, syntax, addressing modes, data formats etc. The 32-bit ARM architecture, such as ARMv7-A (implementing AArch32; see section on ARMv8 for more on it), was the most widely used architecture in mobile devices as of 2011 . This document describes, as completely as I am aware of, the ARM instruction set. Let's take up another example. Introduction ⢠It focus on the various instruction set of CORTEX M3 and example for each 5/22/2018 4Dept. Instructions are stored word-aligned, so the least significant two bits of instruction addresses are always zero in ARM state. The status register (APSR) contain four flags N, Z, C and V which means the following:. ⢠Allows several operations to be undertaken simultaneously, rather than serially. Thumb and ThumbEE instructions are either 16 or 32 bits long. 0000006541 00000 n For example − The AND operation can be used for clearing one or more bits.
