How Interrupt Handling Works?

Leave a Comment / Embedded System, Job Interview Preparations / By

Interrupts are a fundamental part of modern computer systems, allowing for devices and programs to communicate with each other in real time. Interrupts are signals sent by hardware devices or software programs to the processor, indicating that a specific event has occurred and requiring the processor’s immediate attention. Interrupts can be triggered by a variety of events, such as user input, a system timer, or data arriving from a network. Interrupt handling is the process of managing these interrupts and responding to them in a timely and efficient manner.

MCAL Layer in Autosar: The MCAL layer is responsible for controlling the microcontroller hardware peripherals, such as ADC, SPI, CAN,LIN,FLS,timers and others. It provides standardized interfaces to the higher-level software layers, such as the device drivers and the operating system. This standardization allows for easier development of automotive software, as software developers do not need to have knowledge of the specific hardware being used.
