Survivable Avionics Computer System.
Abstract
This contract has shown by the examples of navigation and flight control that the CHAMP approach to architecture design can be applied to avionic computational problems. Furthermore, the simulations have shown that CHAMP can provide a potentially survivable computer for aircraft use. CHAMP uses a simple network which can make use of advanced hardware techniques (such as those available through the VHSIC program). It also simplifies material inventory problems since there is only one type of spare (a single PC) which is contained in a single chip. The PC used in this study is well within the capability of single-chip techniques projected for DAIS the 1985 time period. The avionics functions software used in this study were created by using DAIS project personnel structured programming techniques which yielded sub-modules for each function that were small and tractable and easily managed by microprocessor-based computers of modest capability. This is especially significant considering that this can be accomplished with processors operating at relatively low-frequency clock rates (1 MHz as opposed to the 10 to 20-MHz clock often used in more elaborate processors). This results in a much more reliable and easily constructed hardware module for the computer. Furthermore, this relative simplicity tends to make the computing modules immune to noise, interference, and EMP.
