The latest development was a PCI card (“ASV5“), equipped with a fast PowerPC processor controlled by an embedded real-time operating system (Jaluna, Chorus OS) with a POSIX layer. My task was to detail and implement the existing design concept by creating specifications for individual processes. An important criterion was achieving a response time of 1-10 ms. I worked on tasks in the areas of interprocess communication and database programming (including base classes, process state machine, MIPC, event handling).

In application development, the focus was on reengineering, code stabilization (Insure), automation of the software generation process, and remote control of the decentralized control computer.
