I'm working on a SHARC audio processing application that needs to receive 4 I2S streams at different sample rates and convert them to a common 44.1 kHz reference. The 21489 has 4 hardware sample rate converters. How many of the SHARC serial ports do I need to use? From reading the manual, it looks like each SRC would need a separate SPORT on the input and on the output. This would mean 8 serial ports would be used? Could you please confirm?
I also have additional audio inputs and outputs using TDM that will require serial ports. Is there any way to utilize the SRCs without consuming all 8 SPORTs?
