Wouldn't that depend on whether or not the LCD controller was bus-mastering? If so the CPU utilization for the LCD controller would be negligible, with the only delays coming in those cases where there were bus contention between the LCD controller and the running CPU core. If memory access were the only problem then presumably certain benchmarks that were more memory-intensive would be affected greater than the non-memory-intensive ones, and that doesn't seem to be the case. Case in point: Using test versions of Power48 I can measure how many instructions it emulates per second during both idle modes and active calculation. The speed 'loss' of the T3 appears to be uniform across the board with regards to processor / memory utilization. > > I don't have a T3 to test, but I wonder if the display configuration > or display refresh depth or rate could be changing on wake-up, > and differently from after a soft reset? > Hey, sounds like a good test! I'll see if I can run this experiment tonight and report the results back to the forum. -Robert -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
