The ARM (Advanced Reduced Instructions set computer ) Microcontroller has a 32-bit RISC. In 1987, Acrons computer’s organization established ARM Microcontroller. The different manufactures such as ST microelectronics, Motorola, etc, developed the ARM Microcontroller. It is also known as Brain of an Embedded System. There are several Best Embedded System Courses in India are available thats assists you to operate all Hardware Components.
ARM Processor is one family of CPU based on RISC Architecture developed by ARM Microcontroller. Example of an ARM Processor is the Raspberry Pi Product that fits into the user pocket and works on 256 MB of RAM. It is simplified design with more efficient and makes easy coding for developers.
- Load / Storable Architecture
- Orthogonal Instructon set
- Single cycle Execution
- Developed Power saving design
- Hardware virtualization support
The ARM Microcontroller are used in electronic devices such as Mobile phones, PDA, Digital Media, Music Players , Calculators, and all hard drives. It has reduced Instruction set, so it need fewer transistors, which enables smaller size for Integrated Circuit. It is efficient that other Higher Microcontrollers.
Difference between ARM and Other Microcontroller:
ARM vs 8051:
Bus width: ARM has 32-bit and also available in 64-bit whereas 8051 Microcontroller is 8-bit for standard core.
Speed: For ARM, 1 clock per Instruction cycle but 8051 Microcontroller was 12 clocks/ instruction cycle.
Instruction Set Architecture: 8051 is CISC whereas ARM is RISC Architecture.
ARM vs PIC:
Bus width: ARM has 32-bit and also available in 64-bit whereas PIC Microcontroller is 8/16/32-bit for standard core.
Speed: For ARM, 1 clock per Instruction cycle but PIC Microcontroller was 4 clocks/ instruction cycle.
Instruction Set Architecture: PIC is some feature of RISC whereas ARM is RISC Architecture.
ARM vs AVR:
Bus width: ARM has 32-bit and also available in 64-bit whereas AVR Microcontroller is 8/32-bit for standard core.
Speed: For ARM, 1 clock per Instruction cycle but AVR Microcontroller was 1 clocks/ instruction cycle.
Other feature: AVR is cheap expensive whereas ARM is vast.
