Other Parts Discussed in Thread: TMS320C5515

Hi All,

We have a TMS320C5515 based prototype board. One of our applications demands to have communication between two I2S.

Lets assume the audio signals from I2S3 has to be given to I2S4.

Can this be acheived?

Thanks & Regards,

Naveen

Hi,

C5515 supports up to 4 I2Ss so you can use any two I2Ss. For a notation point of view, it's I2S0 to I2S3 available.

Regards,

Hyun

The 'C5515 only has 4 I2S buses, I2S0 through I2S3. There is no I2S4.

The easiest thing to do would be to use the CPU to take samples from one bus, and put them on another.

If you want to use DMA, you will have to use two controllers since no one controller can see more than one I2S bus. Thus there will be latency, but that might be acceptable in your implementation.
