#156606 - sometimes, depends Responding to: ???'s previous message |
My questions:
1. As a user how significant would it be to have these optimizations? 2. What are the really important optimizations for developers working with the 8051? 1) sometimes, if you make a) a (high volume) product where you MUST use a uC that is a bit too slow non-oprimized b) a (high volume) product where you MUST use a uC that has a bit too little memory non-oprimized 2) depends, either none or all I would say that you should never oprimize (if needs arise use a larger/faster processor) if a) your volume is less than, say, 1000 units. b) your product is not price sensitive. c) the cost of a sufficient processor is insignificantly more than the insufficient one. Why not optimize? debugging can become a nightmare Erik |
