How Interrupt Handling Works?

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.

Big Endian and Little Endian in Memory

Understanding Big-Endian and Little-Endian Byte Order

When we talk about computer memory, we refer to it as a collection of bytes, each of which is assigned a unique address. In computing, the order in which these bytes are stored is called byte order, and there are two different ways to do it: big-endian and little-endian.

MCAL layer in Autosar

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.
