TMS320C28346 :Could you recommend interface and Processor?

Part Number:TMS320C28346

Hi. Our company used TMS320C28346.

We design Line scan camera with TMS320C28346.

Now we use EMIF INTERFACE for receiving 9bit line scan image sensor data(2k).

And we use about 30M data rate.

But we have to raise speed about 200M data rate. So we need to upgrade dsp level.

Could you recommend line scan interface and Processor?

And we'd like to reduce time about  this( for(i=0;i<2048;i++) {}

Please help me

Thank you
