Too many interrupts?

[windell747]

Hi, I'm in charge of the programming and I was wanting to use interrupts to track the rising edges of the gear tooth sensors. My mentor is concerned that tracking this (max speed of 10ft/sec) will bog the processor down too much. He is proposing to build a byte counter circuit that will keep count will the processor is doing other things and then the count will be read by the processor for an update and reset. Can anyone provide insight to this?

Thanks,
Windell

Please only respond if you are a credible source because I don't want to make myself an idiot to my mentor when I present him with an argument.
