Whois & Analysis for keil.com

The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use.

The cores consist of the Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4(F), Cortex-M7(F), Cortex-M23, Cortex-M33(F).

If the Cortex-M4 / M7 / M33 silicon has the FPU option, then the core is known as the Cortex-M4F / Cortex-M7F / Cortex-M33F.

ARM Cortex-M cores have been shipped in tens of billions of devices.

A microcontroller (or MCU for microcontroller unit) is a small computer on a single integrated circuit.

In modern terminology, it is a System on a chip or SoC.

A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

Program memory in the form of Ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM.

Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

The C166 family is a 16-bit microcontroller architecture from Infineon (formerly the semiconductor division of Siemens) in cooperation with STMicroelectronics.

It was first released in 1993 and is a controller for measurement and control tasks.

It uses the well-established RISC architecture, but features some microcontroller-specific extensions such as bit-addressable memory and an interrupt system optimized for low-latency.

When this architecture was introduced the main focus was to replace 8051 controllers (from Intel).

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.

It is embedded as part of a complete device often including hardware and mechanical parts.

Embedded systems control many devices in common use today.

Ninety-eight percent of all microprocessors are manufactured as components of embedded systems.

An assembly (or assembler) language, often abbreviated asm, is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions.

Each assembly language is specific to a particular computer architecture.

In contrast, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling.

Assembly language may also be called symbolic machine code.
