Hi,
I am using the F28M36P63C2.
I just realized, after performing a servo algorithm by C28, that it was very slow. To do one instruction takes almost 50ns, which corresponds to 20MHz (quartz system clock).
At this point in time, the main question is regarding the performance of the processor. We need a particular servo algorithm (that we already have written) to operate in well under 10 microseconds, and preferably under 5 microseconds. With our latest compiler settings and such, we've got it running down to around 8.5 microseconds, but we'd still like to see if it is possible to get better performance.
I'm configuring the M3 at 75MHz and the C28 at 150MHz.
Is there a way to make the C28 faster or do we have to change device?
Thank you,
Marc
