Evolution of the Intel x86 Architecture

Computer Architecture

• ARM architecture is based on Reduced Instruction Set Computer (RISC) instruction set architecture.

ARM Company

• ARM Holdings is the company responsible for designing ARM-based microprocessors and microcontrollers.

ARM Products

• The Cortex series represents ARM products that are designed for embedded systems.

ARM Chips

• A notable feature of ARM chips is their low power consumption.

IAS Computer

• The fundamental design approach of the IAS computer in the first generation of computers was the von Neumann architecture.

Stored Program Concept

• Mathematician John von Neumann is attributed to the first publication of the stored program concept idea in 1945 for the EDVAC.

First Generation Computers

• Vacuum tubes were used for digital logic elements and memory during the first generation of computers.

ARM Cortex Processors

• A major characteristic of ARM Cortex processors that distinguishes them in the market is their high performance with low power consumption.

Security in ARM

• The TrustZone component is responsible for security in the ARM-based microcontroller chip.

Cortex-M3 Processor

• The Cortex-M3 processor has a Memory Protection Unit (MPU) that is not present in Cortex-M0 or Cortex-M0+ processors.

Serial Communication

• The USART (Universal Synchronous Asynchronous Receiver-Transmitter) interface is typically associated with Serial Communication in the ARM-based microcontroller chip.

Cortex-M3 Core

• The presence of a Memory Protection Unit (MPU) is the feature of the Cortex-M3 Core that distinguishes it from the Cortex-M0 and Cortex-M0+ processors.
