Processor Selection
Hia Bombay.
Firstly aviation has avionics designers but the guys you may bump into here are 'Systems Designers'. ie We take equipment boxes / indicators and provide wiring diagrams and assembly drawings for a fitters to install a complete system in to an aircraft. These designs area approved by a 'Systems CVE'. CVE duties are mainly to verify the safe and approved manor of the system design eg installation materials and techniques. However sometimes we may need to consider component level operation but CPR performance is very rarely one of them.
Your question relates to 'Component Level' design of which is normally of concern of the system manufacturer such as 'Honeywell', 'Rockwell Collins' etc.
Without specific details of what you want this processor to do is a little bit of 'How long is a piece of string' question.
So, what specific application do you have in mind ???
