Goals

• Develop an efficient mechanism for programming
  multiple devices
• Program devices with identical content
• Allow devices to be placed throughout the
  Internet
• Support a hardware-based solution
• No microprocessor or soft core

3
Solution

• A hardware circuit which extracts device
  configuration information from TCP/IP data flow

4
System Configuration

• Programming Station
• Transmits configuration file
• End Station
• Terminates TCP/IP connection
• Acts as data sink
• One or More Target Devices
• Contains programmer circuit target component
• Network Connectivity
• IP route from programmer to each device and end
  station

Summary

• A hardware circuit has been developed which
  supports the simultaneous programming of multiple
  devices
• Devices can be dispersed throughout the Internet
  at disparate locations
• Programming information is transmitted once and
  received by all devices
• Simple to add or remove devices from programming
  chain

15
Multi-Device Programmer

• A hardware circuit which extracts device
  configuration information from TCP/IP data flow
  and programs remote devices
