- 10 bytes * 20,000Hz = 200,000 bytes/s
- 200,000 bytes/s * 10 bits/byte = 2,000,000 bits/s (baud rate) i.e, 2e6.
- The desired baud rate in this case is 2e6 i.e, 2 Mbps.
How can I use a two model approach for signal logging and parameter tuning on a TI C2000?

The two model approach is the fastest way to log data in realtime. In the two model approach, the idea is to create two models, one that runs on the target and sends data to serial. The second one runs on the host and gets data from the target. Here is an example of DC DC buck converter that takes this approach:
Differences between External mode and two model approach:
When using the two model approach
The number of signals that can be logged depends on the baud rate and the rate at which the data is transferred. For example, consider that we need to transfer 10 bytes of data at 20kHz.
On the same lines, using two model approach, the data can be transferred at a higher rate of 200kHz. A maximum of 3 uint16 signals can be transferred at a rate of 200KHz if the baud rate is configured as 12Mbps.
