Consists of a host, USB ports, and peripheral devices connected in a tiered-star topology 3 Slide 4: How Communication Endpoint built into device by manufacturer Endpoint addressable by (device address , endpoint number)as specified in packet sent by host If data from host to endpoint an OUT packet sent If data from device to an IN packet sent by host 4 Slide 5: How Communication Established Device Connected Enumeration starts by sending reset signal Data rate of device determined Device Assigned a unique address If host supports device, driver loaded 5 Slide 6: Past----->Present USB-IF formed USB 1.0 specification 12 Mbit/s USB 2.0 specification 480 Mbit/s USB 3.0 specification 5 Gbit/s 2010 USB 3.0 devices in market 6 Slide 7: WHY USB 3.0 Popularity Transfers HD data in short time Superior than its competitors 7 Slide 8: FEATURES Dual bus architecture Cable sructure supporting full duplex transmission Connector supporting cable structure Power Link level power management Asynchronous notify 8 Slide 9: DUAL BUS ARCHITECTURE USB 3.0 is a physical SuperSpeed bus combined in parallel with a physical USB 2.0 bus 9 Slide 10: CABLE STRUCTURE One power pair One twisted signal pair for USB 2.0 data path Two twisted signal pairs for the SuperSpeed data path. Supports full duplex mode 10 Slide 11: CONNECTOR PINS 11 Slide 12: Power 50% more power provided(100-150mA)for unconfigured device. 80%more power provided(500-900mA)for configured device. Link level power management Continous device polling eliminated 12 Slide 13: SUPER SPEED ARCHITECTURE Physical layer Link layer Protocol layer 13 Slide 14: PHYSICAL LAYER Physical connection between downstream port and upstream port If connected reciever termination enabled No signalling occurs generates LFPS 8 bit data scrambled and encoded to 10 bit,sends to link layer Link layer to physical 14 Slide 15: LINK LAYER Link level power management Insertion of packet delimiters Receive and manage packets Interface between protocol layer 15 Slide 16: PROTOCOL LAYER End to end communication Deals with protocols Reliable delivery 16 Slide 17: SUPER SPEED CONNECTION Device notifies it is connected Host makes request Device ready notifies this with ERDY Else tells host unavailable to process by sending NRDY 17 Slide 18: SUPER SPEED TRANSFER Two channels No propagation delay Data bursting OUT-data packet contains address information IN-sends packet with sequence number that host tells 18 Slide 19: USB 3.0 vs USB2.0 USB 3.0 USB 2.0 Super speed High speed Asynchronous notify Polling Link level power management No such properties 900 mA power 500 mA Full duplex Half duplex 19 Slide 20: USB 3.0 vs FIREWIRE,ESATA 6 times faster than firewire 800 Faster than esata esata cannot provide power USB 3.0 has improved power management, meaning that devices can move into idle, suspend, and sleep states 20 Slide 21: ADVANTAGES Super speed Power efficiency Efficient when compared to its competitors Backward compatibility 21 Slide 22: DRAWBACK Intel at present not supporting Cable length limited to 3m 22 Slide 23: FUTURE Twisted pair cable replaced by optical fibre 23 Slide 24: CONCLUSION USB 3.0 wil also be popular like earlier versions. Will replaces firewire etc As it is backward compatible it will be used in the new computers and devices 24 Slide 25: REFERENCE  en.wikipedia.org/wiki/Universal_Serial_Bus USB 3.0 specification released by USB consortium www.usb.org/developers/docs  www.inno-logic.com/resourcesUSB3.html  deviceguru.com/superspeed-usb-promises5gbps 25 Slide 26: THANK YOU 26 You do not have the permission to view this presentation.
