Flight Computer Architectures
There have been several implementations of a flight computer application. Follow links from the table to find out more about them.
| Architecture | Airframe | Architect | Language | Notes |
|---|---|---|---|---|
| LV1b Flight Software | LV1b | ?AndrewGreenberg | PIC assembler | Worked admirably |
| CanMuxer | LV2 | ?JameySharp | C++, pthreads | Got as far as a working dispatcher with TCP I/O |
| Renegade | LV2 | ?JamesPerkins | C, processes | Got CAN and UDP messages talking, and logger working |
| FifoArchitecture | LV2 | ?JamesPerkins | C, processes, named pipes | CAN, UDP, logger working. Sequencer and GPS->ATV interpretation is starting to come together |
| BlackboardArchitecture | LV2 | ?BartMassey | C, pthreads | Parts of this adopted, along with threading, in late 2004 |
There's also a discussion of CanMuxer, Renegade, and FIFO, the history of moving from one to the other, and a description of all software in the PSAS project, in the Usenix2003Paper topic.
