Posted on May 17, 2011 at 14:14Give the USART interrupts a higher priority/preemption, and make them REAL simple. (ie just FIFO the data and look at it later)
Use DMA for USART Rx
Use a lower priority 800us timer task
Use a worker task to do the computation
Simplify the computation. (ie optimize it, use reciprocal multiplication instead of divides)
Break the computation into smaller pieces, or precompute parts of it.
