Features of ARM Processor

Current manufacturers of the Advanced RISC Machine (ARM) microcontroller include Apple, Nvidia, Qualcomm, Motorola, ST Microelectronics, Samsung Electronics, and TI. The ARM microcontroller was developed by the Acorn computer company. It is a microcontroller that is based on the RISC instruction set architecture and is also known as an advanced RISC microcontroller (ISA). Due to its extensive feature set and suitability for creating products with good aesthetics, it is the most widely used microcontroller and is used by the majority of industries for embedded systems. Learn about the characteristics of ARM processors.

Here are the listed features of the ARM processor

  1. Multiprocessing systems
  2. Memory management
  3. Memory that is tightly coupled
  4. Thumb 2 technology
  5. A large number of resister
  6. Pipelining
  7. One-cycle execution time

Let us have look at the Features of ARM processor

Multiprocessing systems

ARM processors are made to be used in situations where more than one processor is used to process data in multiprocessing systems. The first AMP processor known as ARMv6K had the hardware ability to support 4 CPUs.

Memory management

Memory management is a feature of the ARM processor. Memory management unit and memory protection unit are included in this. These management systems become crucial for effectively managing memory.

Memory that is tightly coupled

ARM processor memory is tightly coupled. This response is very quick. Because of its low latency, it can also be used when cache memory behaves erratically.

Thumb 2 technology

Thumb 2 technology was used to create variable-length instruction sets and was first introduced in 2003. It upgrades the original thumb technology from 16-bit instructions to 32-bit instructions. Compared to thumb technology, which was previously used, it performs better.

A large number of resister

The ARM processor uses a large number of registers to limit memory interactions. Resistors include address and data. These serve as the operating systems' local memory repositories.

Pipelining

Pipelines are used to process instruction in parallel. One pipeline stage involves the breakdown and decoding of instructions. The pipeline advances one step at a time in order to increase throughput.

One-cycle execution time

Each instruction on the CPU is optimized for the ARM processor's one-cycle execution time. Each instruction has a set length, allowing time for retrieval of subsequent instructions before the current instruction is carried out. The clock per instruction for ARM is one cycle.
