GPC Software research

[Urwumpe]

I just found this one when looking for any information about the ALT tests.

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770075091_1977075091.pdf

While it is limited to the software used in the ALT tests, this 1580 page document contains a lot of stuff very interesting for us. I just found the description of the GPC software for handling the MTU.

Possible that I can find much more basic hardware drivers in the description. Which means:

• We can use the flow charts for writing our own GPC software implementation.
• We can use the knowledge, how the hardware is addressed and expected to react, to model the GPC-Hardware interfaces.

GPC software modules, for which I have found flow charts until now:

• Process management
• Master Timing Unit
• I/O processor management (Description is very helpful for modeling the IOP)
• Process error management
• GPC initialization
