Some DMA controllers support direct virtual memory access, where the targets of 1/0 operations are specified as virtual addresses and a translation from virtual to physical address is performed during the DMA. How does this design complicate the design of the DMA controller? What are the advantages of providing such a functionality?

CS - Operating Systems Design Please show work Assume you are designing a new embedded system with a really tiny but maximum physical memory of 4 KB. The MMU in this system supports segmentation + paging. The MMU has a 9-bit virtual address space, of which 3 bits are used to index the segment table and the other 6 bits are used to access the physical memory inside a segment. Recollect that in a segmentation + paging MMU, each segment is divided into a set of pages. Each page inside the segment is 16 bytes. What is the maximum number of pages possible in each segment?
For simplicity, let us assume that each instruction on a RISC processor is executed in 2 microseconds and that an I/O device can only wait for an interrupt to be handled for a maximum of 1 millisecond before it is serviced. The number of instructions that may be executed when interruptions are deactivated is restricted to a certain number.
