I have read that a hardware interrupt is handled asynchronously by the CPU, which means that the interrupt signal may arrive at any point of time with respect to the CPU clock cycle. Now, this means that an interrupt may asynchronously hit the processor when it is in the middle of executing some instruction. " - How does autosar os handle interrupts

Explanation of Interrupt Handling within AUTOSAR

WebInterrupts are the events that signal the processor to service the request. Interrupts can be caused by hardware as well as software. Hardware interrupts are of two types: Maskable and Non-Maskable Interrupts. Software interrupts are generally caused by exceptions and special instructions eg. fork () CPU handles the interrupt and on completion ... WebAn interrupt is an event that alters the normal execution flow of a program and can be generated by hardware devices or even by the CPU itself. When an interrupt occurs the current flow of execution is suspended and interrupt handler runs. After the interrupt handler runs the previous execution flow is resumed.
