WebPolling and Interrupts: In Polling and Interrupts of the microprocessor’s software simply checks each of the I/O devices every so often. During this check, the microprocessor tests to see if any device needs servicing. Fig. 5.1 shows the flow chart for polling subroutine. This is a simple program which services I/O ports A, B, and C. Webinterrupt: An interrupt is a signal from a device attached to a computer or from a program within the computer that requires the operating system to stop and figure out what to do next.

WebInterrupt Cycle: An instruction cycle (sometimes called fetch-and-execute cycle, fetch-decode-execute cycle, or FDX) is the basic operation cycle of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions. WebRegisters in Computer Architecture. Register is a very fast computer memory, used to store data/instruction in-execution. A Register is a group of flip-flops with each flip-flop capable of storing one bit of information. An n-bit register has a group of n flip-flops and is capable of storing binary information of n-bits.

WebDec 7, 2016 · ISR: Stands for "Interrupt Service Routine." An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. It handles the request and sends it to the CPU , interrupting the active process . When the ISR is complete, the process is resumed.
