What does ARM mean in embedded?

Arm is a British company that literally means Advanced RISC Microprocessor. Arm is providing customers with 16 32-bit embedded RISC microcontroller solutions, licensing its RISC processors to electronics companies, and is becoming the standard in portable communications, handheld computing devices, consumer and digital multi-solutions. �0�2

ARM7 and ARM9 are two sub-series of the ARM series, ARM9 is more powerful, and it has other sub-series. ARM is a company that only does design and does not produce, it provides a variety of ARM cores with different performance, if a company like Motorola can use the ARM cores it provides, plus related IO resources, memory, programmable components to form their own 32-bit RISC embedded monolithic processor. Motorola has recently adopted ARM in its Dragon Ball processors, and Atmel's AT91 series is also an internal 32-bit external 16-bit processor with ARM cores.

ARM, short for Advanced RISC Machines, can be considered both the name of a company, a generic term for a class of microprocessors, and the name of a technology. It has the advantages of low power consumption, low cost and high performance.

ARM is an abbreviation for Advance RISC Machines, and RISC (Reduced Instrument Set Computer) is a reduced set of instructions.

An embedded system generally refers to a non-PC system, a device or device that has computer functions but is not called a computer. It is an application-centric, software and hardware can be reduced, and it adapts to the comprehensive and strict requirements of the application system for function, reliability, cost, volume, power consumption, etc. To put it simply, the embedded system integrates the application software and hardware of the system, similar to the way the BIOS works in the PC, with the characteristics of small software, high automation, and fast response, which is especially suitable for systems that require real-time and multi-tasking.

The embedded system is mainly composed of embedded processors, related supporting hardware, embedded operating systems and application software systems, etc., which are "devices" that can work independently.

Embedded systems include almost all electrical devices in life, such as PDAs, mobile computing devices, TV set-top boxes, mobile phone Internet access, digital TV, multi**, automobiles, microwave ovens, digital cameras, home automation systems, elevators, air conditioners, security systems, vending machines, cellular**, consumer electronic devices, industrial automation instruments and medical instruments, etc.
