Changing multiple parameters

Hi,

 

I am using the SigmaDSP in a real time situation where several similar elements need to change at the same time.

For example an EQ curve on several channels.

 

I am normally controlling the ADAU1442 from I2C but to change say 4 curves on 4 channels takes many commands and obviously adds a latency issue which I am trying to avoid.

 

For

 

So the question is:

 

1. is it possible to send a command to several components to change at the same (or at least near same) time

2. is SPI faster than I2C to update parameters

 

 

Thanks

Danny
