Re: LPC2294 External Bus Speed

2005-07-05 by itsjustimpossible

Hi
Thanks for the suggestion but we already have it configured with zero 
wait states etc. So the bus should be running as fast as possible.

I have been doing some experiments today and I think the bus access is 
probably OK. I think the main source of delay is the interrupt latency 
of the FIQ which seems to be about 800nS.

There is also some jitter on that, so all together I am not sure if 
the ARM7 is capable of doing what I need in this instance.

Bit of a shame

Best regards
Simon
