In article , John Cook wrote: Just the official reports!!, Lockheed has only purchased enough processors for 155 F-22's because there out of production, the demand for Air to ground operations has increased the demand on processing power, something the original processors are not quite upto hence the _need_ for the 'upgrade'. So the processors are obsolete, (too old)... the Avionic architecture needs to be replaced before the F-22 can become the F/A-22 because the present system is based on the old processors and rewriting the code is pointless on an obsolete system, that would only support half of the F-22 fleet Methinks there's some confusion there between processors, avionics architecture, and software. While it's true that Intel tried to shut down i960 production causing a chinese fire drill, there are enough assets to get by until a new processor is ready. Full disclosu I'm a retired electrical engineer. I specialized in high-end embedded microprocessors, which the "i960" in the F-22 is. I know nothing about designing aircraft. I do know a little about the Intel processor at the heart of the F-22: The i960MX was designed by Intel specifically and solely for the F-22. Nope, the i960 is a processor designed to control printers. http://www.gao.gov/cgi-bin/getrpt?GAO-04-391 "The F/A-22 is dependent on its onboard computers and software to perform its mission. Unlike other fighter aircraft, it has a highly advanced,integrated avionics system capable of detecting, identifying, and engaging the enemy at ranges beyond a pilot's vision. The key to the F/A-22 avionics lies in its fully integrated core architecture and its two central, networked computers called common integrated processors (CIP).CIPs use very high-speed integrated circuits to collect, process, and integrate data and signals from the aircraft's sensors. CIP serves as the "brains" for the F/A-22's integrated avionics system and is unique to this aircraft. The primary processor in CIP is the Intel i960MX microprocessor,which is used strictly for avionics processing. This microprocessor is based on 1990's technology and has a 32-bit processor that operates at speeds of 25mhz." etc. Caught bull****ting again Splappy? Not me. Do you even have a clue what you cut and pasted, moron? As Mr. cook pointed out, the i960 is very obsolete. |
