Webdata access in blocks of a fixed size. The interface is typically used for data storage devices. The mmap services include the following subroutines: The msem_init, msem_lock, msem_unlock, msem_remove, msleep, and mwakeupsubroutines provide access control for the processes mapped using the mmapservices. WebExample: Network Interface Card Host I/O bus Adaptor Network link Bus interface Link interface • Link interface talks to wire/fiber/antenna - Typically does framing, link-layer CRC • FIFOs on card provide small amount of buffering • Bus interface logic uses DMA to move packets to and from buffers in main memory – p. 7/27
