Goodmorning Community,
In the following situation
| Software | |RF |
| Code | ---> |Front End |
| | |(Sample_Rate) |
Underflow occurs when the software code does not provide
samples at a constant rate as required by the RF-Front End.
The known solution, able to eliminate Underflows, is clearly speed up
the software code. However, in this discussion I want to understant
if there exist alternative methods, keeping the software as it is.
One thing that comes in my mind is to collect a certain number of
processed samples
in a FIFO before starting the RF-front end transmission, ensuring that
there are always samples in the FIFO buffer (clearly for a limited
period).
| Software | | Implement | |RF |
| Code | ---> | FIFO | ---> |Front End |
| | |(synch with FE) | |(Sample_Rate) |
Could it be implemented (if it make sense)?
Can you guide me to implement such block?
(in particular the Forecast, I think it will a general block)
Thank you very much,
simone
