What is ARM?

ARM is a family of instruction set architectures for computer processors based on a Reduced Instruction Set Computing (RISC) architecture developed by British company ARM Holdings – arm.com

ARM Holdings develops the instruction set and architecture for ARM-based products, but does not manufacture products – it licenses its ARM core designs to semiconductor manufacturers such as TI, ST, Atmel, NXP, Freescale, Cypress, Renesas etc.

ARM IP is in 32-bit and 64-bit RISC microprocessors and microcontrollers, graphics processors, enabling software, cell libraries, embedded memories, high-speed connectivity products, peripherals and development tools.

ARM chips are ubiquitous – used in everything from cell phones, tablets, cable boxes, smart meters, hard drives, routers, etc.

What is ARM? - continued

In the early 'pre-ARM' days, ARM stood for Acorn RISC Machines. Then when ARM became a separate company, ARM became Advanced RISC Machines and the modern name is just ARM.

VLSI Technology produced the first ARM silicon on 26 April 1985. It worked the first time, and was known as ARM1.

Three main ARM series – A, M, R

ARM Cortex-A Series The ARM® Cortex®-A series of application processors provide a range

of solutions for devices undertaking complex compute tasks, such as hosting a rich Operating System (OS) platform, executing a user interface and supporting software applications.

Cortex-A series processors can be found in a range of the highest performing consumer devices, including a spectrum of smartphones from ultra-low-cost to high-end flagship devices, mobile computing platforms, digital TVs, and set-top boxes, but can also be found in enterprise networking, printers and server solutions.

ARM Cortex-R Series The ARM® Cortex®-R real-time processors offer high-performance computing

solutions for embedded systems where reliability, high availability, fault tolerance, maintainability and real-time responses are required.

There are many applications requiring the key Cortex-R series attributes of :

High performance: Fast processing combined with a high clock frequency

Real-time: Processing meets hard real-time constraints on all occasions

Safe: Dependable, reliable systems with high error resistance

Cost effective: Features for optimal performance, power and area.

ARM Cortex-M Series

The Cortex-M family is optimized for embedded MCU use in cost and power sensitive MCU and mixed-signal devices for applications such as Internet of Things, connectivity, smart metering, human interface devices, automotive and industrial control systems, domestic household appliances, consumer products and medical instrumentation.

And the Hobbyist’s favourite series!

However, ARM microcontroller chips are not the cheapest – e.g. Microchip PIC32 (MIPS M4K architecture) chips with equivalent functionality/memory are less expensive.

ARM Technology Partners

ARM Holdings has over 175 technology partners. A few are shown below.

ARM Microcontroller IDE’s/Compilers

Is very difficult for hobbyists to get decent ARM development tools.

Atmel provides Atmel Studio 6 IDE with C/C++ compiler suite free of charge – fully functional, not crippled. Is based on MS Visual Studio – Windows only.

Microchip provides MPLABX IDE free of charge. Is based on NetBeans IDE. Compilers are separate – free ones do not support code optimization. Licensed version costs USD$900.

None of the ARM microcontroller manufacturers provide any free tools. They simply refer you to third part IDE/compiler vendors such as : IAR, Atollic TrueStudio, Keil MDK etc. These vendors do not publish prices – you have to apply for a quote on-line! - E.G. Attollic TrueStudio – USD$2795!!

Available Free Open Source IDE’s

Eclipse – http://eclipse.org. Java based, originally intended for Java development but has extensions for C/C++ and other languages, e.g. PHP for Web development.

Eclipse is a generic modern IDE only – it has to be integrated with a C/C++ compiler toolset.

NetBeans – https://netbeans.org. Also Java based, originally intended for Java development but has extensions for C/C++ development. NetBeans IDE is the official IDE for Java 8.

NetBeans is a generic modern IDE only – it has to be integrated with a C/C++ compiler toolset. David Harrison – January 21, 2015

Almost Free Open Source IDE’s Atollic TrueSTUDIO for ARM Lite v5.2.1

Stripped down version of their TrueSTUDIO Professional. Has a 32KByte firmware size limit.

Keil MDK ARM Lite Stripped down version of their MDK ARM Professional. Has a 32KByte firmware size limit.

Microsoft Visual Studio – Community Edition 2013 http://go.microsoft.com/fwlink/?LinkId=517284 then add VisualGDB from Sysprogs – VisualGDB embedded edition is USD$89.00

MicroElektronika (Belgrade, Serbia) – ARM Integrated IDE/C Compiler USD$299, MikroProg ARM programmer – USD$49

ARM Development Tools Setup Process

Since both Eclipse and NetBeans are Java based you must have Java installed FIRST - suggest you get the latest version from java.com. NOTE : You need the JDK (Java Development Kit, not just the JRE)

Install the IDE of your choice.

Install the GNU Compiler toolchain for ARM Embedded.

Integrate the IDE with the Compiler toolchain and possibly GDB for live debugging capability.
