What is AUTOSAR Development Partnership and AUTOSAR MCAL Layer

AUTOSAR Development Partnership

AUTOSAR, which stands for AUTomotive Open System Architecture, is a partnership at a global scale between Automotive OEMs, Tier-I suppliers, semiconductor vendors, embedded hardware design houses and embedded software engineering service providers

This worldwide strong partnership has its roots in one common belief – “Cooperate on standards, compete on implementation” as mentioned in the AUTOSAR charter.

Goals of the AUTOSAR Development Partnership

  • Standardization of basic software functionality of automotive ECUs
  • Scalability to different vehicle and platform variants
  • Transferability of embedded software
  • Support of different functional domains
  • Definition of an open AUTOSAR architecture
  • Collaboration between various embedded partners
  • Development of highly dependable systems
  • Support of applicable automotive international standards and state-of-the-art technologies

What is AUTOSAR MCAL Layer?

MCAL (Microcontroller Abstraction Layer), conforming to the microcontroller abstraction layer of AUTOSAR specifications, is the driver module of the infrastructure software. MCAL realizes notification mechanism to support instruction, response and information distribution to different processes. The main components are DIO, ADC, PWM, PWD, EEP, FLS, CCU, WDT, SPI, IIC etc.

What is AUTOSAR Layered Architecture?

AUTOSAR uses a three-layered architecture:

  • Basic Software (AUTOSAR BSW): Basic Software is the standardized software layer, which provides services to the AUTOSAR Software Components and is necessary to run the functional part of the software. It does not fulfill any functional job itself and is situated below the AUTOSAR RTE (Runtime Environment). The Basic Software contains standardized and ECU specific modules.
  • Runtime environment (AUTOSAR RTE): Middleware which abstracts from the network topology for the inter- and intra-ECU information exchange between the application software components and between the Basic Software (BSW) and the applications.
  • Application Layer: application software components that interact with the runtime environment (RTE).
