8.  DE2 board ◦ Connected to PC through USB port, using Philips USB controller.  USB webcam ◦ Connected to PC through USB port.  USB connection service program ◦ Should be written for Windows OS. (C++) ◦ Reads frames from camera. ◦ Sends frames to USB port using OS services. 8

9.  DE2 is connected to LAN. ◦ DM9000A PHY/MAC Controller supplies an Ethernet interface for NIOS II. ◦ UPD/IP over Ethernet should be Implemented using IDE2. ◦ Possible implementation of ARP and DHCP.  Remote computer is connected to LAN.  UDP service program. ◦ Should be written for Windows OS. (C++) ◦ Accepts UDP frame packets from the SOPC. ◦ Uses buffering. ◦ Displays video stream.  9 LAN

10. 10 System Component Rate (Mbit/s) Ideal Stream Frame Size Limitation for 15 FPS (pixels / frame) Notes USB 2.0 is used. 480 1100X1100 Connects between local PC and DE2. Fast Ethernet100500X500 Refers to DE2 port and PC network cards. NIOS II loaded to Cyclone II can process up to 400M instructions Per second

11. CPU 11  Two memory buffers will be allocated on chip memory. ◦ Each one with a size of constant number of UDP packets.  Operation sequence (Assuming buffer B is ready): DMA transfer A ended Interrupt Start DMA transfer: USB  buffer A Send Buffer B to network using UDP packets Buffer_A_Ready_Flag = TRUE Wait for Buffer_A_Ready_Flag DMA transfer Same with B and A replaced

12. 12  USB protocol will be implemented over Philips ISP1362 USB controller.  UDP sender will be implemented over DM9000A mechanism.  A USB connection service program should be written and run on local computer.  A UDP service program will be written and run on remote computer.  DMA will be used in order to achieve parallelism.
