High speed 16b paralell bus to DSP

Hello, i am quite new with FPGA, and need ideas how to solve my problem. I have 128 points CCD, and i control detector as well as ADC from FPGA. FPGA connects to DSP processor by standard SRAM ...

DSP have very slow IO, even flag toggle only give 20-40MHz, while STM32F407 running at 168MHz can give 84MHz toggle speed.

Other reason is that not only i just started to work with FPGA, same apply to ADSP-21489. very lite help can find in my university regarding dsp programming, no sample code since compiler cost 10K$, and i only could do programming to boot flash so no debugging, that means programming also not that simple ( troubleshooting )

Test show that AMI interface is capable >30MHz (free running) so i will try to use that. If you know more about PDAP port let me know, since i made development kit with all pins connected to header, so i can switch from AMI to PDAP if that could help me
