WebFeb 7, 2024 · What is an Interrupt Interrupt is an event that changes the program flow i.e. the instruction stream being executed by the CPU. Interrupts are also generated by various devices connected to the CPU or they caused by bugs within the software. Interrupts are way for hardware to signal to the processor. Interrupts and Exceptions Exceptions… WebThe trap is a signal raised by a user program instructing the operating system to perform some functionality immediately. In contrast, the interrupt is a signal to the CPU emitted by hardware that indicates an event that requires immediate attention. A trap also triggers OS functionality. It gives control to the trap handler. WebYes they both are connected to two different interrupts. one to int0 and other to int1.

WebInterrupt is a mechanism by which an I/O or an instruction can suspend the normal execution of processor and get itself serviced. Generally, a particular task is assigned to that interrupt signal. WebInterrupt capabilities: Because DSPs are intended for operation in real-time systems, efficient, sophisticated, and predictable interrupt handling is critical to a DSP. RISC processors, with their highly-pipelined architectures, tend to have slow interrupt response times and limited interrupt capabilities. Context switches should be very fast.
