[9:19 am, 24/01/2022] Ahmed: a. Refer the following MIPS code snippet. Describe the interrupt processing from the line code 9 11 using Interrupt-Driven I/O. Use an illustration to support your answer. [9:20 am, 24/01/2022] Ahmed: b. One of the evolutions in I/O function is I/O has a local memory of its own. Explain ONE (1) I/O device that use this architecture and how it affects the computer performance. [9:20 am, 24/01/2022] Ahmed: c. I/O modules is one of the third key element in computer system. An I/O module is more than just a set of mechanical connectors for connecting a device to the system bus. This is because when designing a computer, the computer engineer needs to consider several issues whether to connect the peripheral directly to the system bus. Explain TWO (2) of these design issues.
