- Central_Air_Data_Computer abstract "The Central Air Data Computer was a groundbreaking integrated flight control system developed by Garrett AiResearch and was used in the early versions of the US Navy's F-14 Tomcat fighter. It is notable for its early use of AiResearch's custom-designed MOS-based LSI microprocessor chipset, the MP944.The CADC was designed and built at Garrett AiResearch by a team led by Steve Geller and Ray Holt, and supported by the startup American Microsystems. Design work started in 1968 and was completed in June 1970, beating out a number of electromechanical systems that had also been designed for the F-14.The CADC consisted of an A-to-D converter, several quartz pressure sensors, and the MOS-based microprocessor. Inputs to the system included the primary flight controls, a number of switches, static and dynamic air pressure (for calculating stall points and aircraft speed) and a temperature gauge. The outputs controlled the primary flight controls, wing sweep, the F-14's leading edge "glove", and the flaps.The MP944 contained six chips used to build the CADC's microprocessor, all based on a 20-bit fixed-point-fraction two's complement number system. They were the Parallel Multiplier Unit (PMU), the Parallel Divider Unit (PDU), the Random Access Storage (RAS), the Read Only Memory (ROM), the Special Logic Function (SLF), and the Steering Logic Unit (SLU). The complete microprocessor system used one PMU, one PDU, one SLF, 3 RASs, 3 SLUs, and 19 ROMs.In 1971 Holt wrote an article about the system for Computer Design magazine, but the Navy classified it, and finally released it in 1998. For this reason the CADC and MP944 remain fairly obscure in spite of their historical importance.In the 1970s, most processors had no larger than 8-bit architectures. The 1971 Intel 4004 was only 4 bits, with clock rates up to 740 kHz; the 1972 Intel 8008 had a maximum clock rate of 500 kHz and used an 8-bit word. This made them far slower than the 1970 F-14 Tomcat's MP944, with its 375 kHz clock rate and 20-bit word size.".
