I'm running an Atmel ARM7TDMI on a prototype board I wire-wrapped and am monitoring the system with an oscilloscope. By comparing the clock pulses to the read/write pulses, I'm finding that single-byte store and read operations are taking literally 50-100 clocks. Naturally this is unacceptable for any purpose, and is obviously a sign of something being majorly wrong. I've read all the literature on the ARM I can find including all of Atmel's documentation and white papers. Does anyone have any idea what this might be?
