Cyclic Redundancy Check Computation: An Implementation …

During USB communication, data is transmitted as packets. Initially, all packets are sent from the host via the root hub, and possibly more hubs, to devices. Some of those packets direct a device to send some packets in reply. After the sync field, all packets are made of 8-bit bytes, transmitted least-significant bit first. The first byte is a packet identifier (PID) byte. The PID is actually 4 bits; the byte consists of the 4-bi… WebMay 5, 2009 · Cyclic Redundancy Check, or CRC, is by far the most popular one.
