Abstract:

An avionic digital signal processing system for a plurality of different types of input sensors such as radar, electro-optical, and electronic warfare that comprises a PI bus operating at 12. 5 MHz and a data network subbus operating at 20 MHz. A plurality of array processor groups each having a plurality of 1750 CPU's are controlled over the PI-bus and receive their sensor inputs over the subbus data network. A plurality of general purpose 1750A computers are connected to the PI-bus for communicating control and narrow band information. A distributed operating system resides in the 1750A central processing units and includes provision for re-routing the signal paths in the event of failure of modules.
