The answers are listed below. Drag and drop the answer into the empty boxes per number. 1. device. 2. 3. 4. 5. 6. polling 7. CPU memory mapped service for an I/O device. 10. arbiter device controller vectored interrupt advanced peripheral bus (APB) control signals interrupt bus daisy chain sequential interrupt device driver non-vectored interrupt register maps branch and link DMA I/O device nested interrupt AMBA DMA controller is the master mind of the AMBA bus. It controls how to navigate the dataflow of data. is the main communication channel in a computer system. is the type of I/O interface method where an I/O device can communicate directly to a memory with an additional controller. This way the CPU can run simultaneously while the data transfer is taking place. is the master mind of a computer system. This is where the OS resides. advanced high performance bus (AHB) isolated I/O single bus integrated DMA is the type of I/O interface method where we have to constantly probe the status of the 1/0 is the type of I/O interface method where an asynchronous signal triggers and requests are the peripherals that humans use to interact with the computer system. 8. is the type of communication where CPU or I/O devices write unto one shared memory. CPU can modify configurations on the device's allocated memory space. 9. is the type of interrupt where each interrupt source sends a unique code to distinguish the source of the interrupt. is the interrupt handler where an interrupt can interrupt an interrupt. "Interruptception".
