#82886 - very complex bit testing Responding to: ???'s previous message |
I did once a long time ago do a complex bit testing by having a 256 byte table of "action codes" that I looked up with the contents of the bit register as offset. If e.g. bit 5 was the most important, all "action codes" that had bit 5 set would "do bit 5 and reset it" then do anothet lookup.
This for complex bit testing, especially when bit combinations matter, this is a lot faster than jb, cjne etc. Erik |
