WebNow coming to Interrupt I/O. Interrupt I/O is way more frequent than DMA. A process usually undergoes I/O plenty of times. Asking for a input from the user would be an interrupt I/O. Not DMA. There are two types of interrupts. Software Interupt; Hardware Interupt; Each interrupt has a special number assigned to it. WebSep 24, 2003 · Many complex functions that are performed in a single, albeit slow, instruction in a CISC processor may require multiple instructions in a RISC. To reduce the memory costs of these extra instructions, consider a processor with Thumb. RISC vs CISC Technology. Many of today’s most popular 32-bit microcontrollers use RISC technology.
http://dtucker.cs.edinboro.edu/CSCI380/Spring2024/Chapter5Answers.html WebInterrupt cascadingallows multiple interrupt sources to share one interrupt vector. This pattern is typically used by an operating system to group multiple relevant services together under one entry point. For example, DOS uses 0x21 for its services; all software interrupts on ARM processors share a single vector, 0x0008.
