ARM processors, developed by a British company called Arm Holdings, are used widely in various types of devices like smartphones, mobile computers, mobile computers and many other electronic devices. ARM architecture is used in their devices by big organisations such as NVidia, Apple, ST microelectronics, Samsung Electronics, NXP, Texas Instruments, Qualcomm, etc.
ARM Architecture
ARM has several sets of processors having different features and different cores. ARM architecture started with 26 bit processors, followed by 32, and is available in 64 bit nowadays. The ARM series begins from ARM7 and moves to ARM11 with useful features such as cache, MMU, Data Tightly Coupled memory, MPU, and many more.
ARM uses Communication protocols such as LIN, CAN, USB, Ethernet, UART, DSP, IrDA, and USART. It uses flash, EEPROM and SDRAM memory. With RISC architecture, it has a speed of one clock/instruction cycle. The best feature of ARM is its ability to give optimum performance at low power.
ARM Cortex Series[/i][/b]
The different series of ARM are ARM Cortex A series, ARM Cortex R series, ARM Cortex M series.
ARM Cortex A Series
ARM Cortex A series, also referred to as “Application” profile (A-profile), is used for application purpose only. It comprises of set of 32-bit and 64-bit RISC ARM processor. 32-bit ARM Cortex A series includes Cortex-A5, A7, A8, A9, A12, A15, A17 MPCore, and A32; while 64-bit cores includes Cortex-A35, A53, A57, and A72. Both 32-bit ARM Cortex-A32 and 64-bit ARM Cortex-A cores make use of ARMv8-A profile belonging to ARMv8 architecture.
ARM Cortex-R series
ARM Cortex R series is widely used for real time application purpose where Low Latency, real-time processing, and Protected Memory (MPU) play vital roles. It comprises of Cortex-R4, R5, R7, and R8.
ARM Cortex-M series
ARM Cortex M series is specially designed for microcontroller based devices where connectivity, energy efficiency, cost, and code reuse are indispensable factors. Various Cortex-M series are M0, M0+, M1, M3, M4, and M7.
ARM Architecture and Programming Training
Since ARM processor finds wide applications in various devices used by different segments of industry, understanding ARM architecture and learning ARM programming can prove out to be very useful for the candidates who are looking out for high paying job in a top notch organization. An individual can get in-depth understanding of ARM based microcontroller or its architecture by enrolling in ARM training courses or ARM7 Online Course. ARM training courses will be beneficial for the candidates who work on microcontroller architecture, engineers, and embedded system developers. The online option would suit professionals who can’t attend classes physically, but want enhance their knowledge by checking out videos lecture conducted by eminent professors, and study materials prepared by experts; working on assignments, and preparing projects at a time and place of their convenience.
