Initial version of the wiring diagram. Currently only includes wiring from PC Sealevel cards to I/F panel.

PDF version of the file also attached.

There are currently 3 functions that the FPGA will serve:

1. Timing and synchronization. It puts out 5 bits of an 8Hz count plus a signal that goes to the parallel port pin 10 of each computer, which should generate CPU interrupts on rising edges. We will use this for timing among the 3 computers to keep them in synch.
2. Sonar control. Our sonars are 10ns TTL triggered, and responds with a short pulse. The time between the 10ns trigger and the response pulse tells us how far an object is from the sonar. The FPGA will conduct this at 8Hz or 16Hz and interface with a computer by sending the computer the measured time difference.

Project Zeus will utilize 3 different computers for navigation, sensor and actuator I/O, and user interaction. One challenge to a computer network like this in a real time operation is the issue of timing and synchronization.

Imagine the sensor computer receiving real time data from a camera, updated at 30fps and processed to provide offset information every 1/8 of a second. How does another computer who is controlling the actuator utilize this information on a timely basis?

This paper will discuss the different solutions of synchronizing operation among a group of networked computers.
