RE: [motoroladsp] questions about signal processing
If you are talking about the 56F8xx family, the ADC can be started and synchronized by a QuadTimer. Arming the ADC "SYNC" input will cause the conversion to start via the QuadTimer. Also the interrupt service routine for the ADC or QuadTimer can be used to output a new value to a DAC. maintaining synchronism between the ADC Samples and the DAC update. Using fast-interrupt, or custom interrupt routines, very low latencies can be achieved between ADC sample, and DAC update. With regard to filling alternate buffers, it seems to me that most algorithms use a "circular" buffer and continuously run the transforms at the same rate as the ADC conversions thus not needing multiple buffers!!! Also check the motorola App Notes regarding the PWM, ADC, and QuadTimer Synchronization. Best Regards,
