What does ARM architecture mean?
The “R” in the acronym “Arm” actually stands for another acronym: Reduced Instruction Set Computer (RISC). Its purpose is to leverage the efficiency of simplicity, with the goal of rendering all of the processor’s functionality on a single chip.
What are the different types of ARM architecture?
Designed by ARM
| Product family | ARM architecture | Processor |
|---|---|---|
| Cortex-R | ARMv8-R | Cortex-R82 |
| Cortex-A (32-bit) | ARMv7-A | Cortex-A5 |
| Cortex-A7 | ||
| Cortex-A8 |
What are the main features of ARM architecture?
ARM features include:
- Load/store-based architecture.
- Single-cycle instruction execution.
- Consistent 16×32 bit register file.
- Link register.
- Easy decoding and pipelining.
- Power-indexed addressing modes.
- Fixed 32-bit instruction set.
What are the applications of ARM microcontroller?
Application of ARM Microcontroller This board is used in different types of techniques used in space and aerospace. Different types of medical devices such as MRI machines, computed tomography scanners, ultrasound machines. It used in different types of accelerators, nuclear reactors, and X-ray machines.
What is ARM architecture in embedded system?
The ARM architecture is a widely used 32-bit RISC processor architecture. In fact, the ARM family accounts for about 75% of all 32-bit CPUs, and about 90% of all embedded 32-bit CPUs. ARM Limited licenses several popular microprocessor cores to many vendors (ARM does not sell physical microprocessors).
What is ARM known for?
ARM is an intellectual property provider, responsible for designing the architecture used in low-power, highly efficient chips that power smartphones, hard drives, and other devices. It describes itself as the R&D department for the entire semiconductor industry.
When was ARM architecture created?

What are the three types of ARMs?
The arm can be divided into the upper arm, which extends from the shoulder to the elbow, the forearm which extends from the elbow to the hand, and the hand.
What is difference between ARM processor and microcontroller?
The LPC2148 is a microcontroller, so is any Cortex-M (this far). Farnell calls some of Freescale’s Cortex-A “Microprocessors”, even though they have embedded features. ARM1 on the other hand, is a microprocessor; it was designed for a computer and required external memory and peripherals.
