I am putting together an application for OMAP 3530 SoC. This application will run some user interface code on embedded linux and invoke waveform generation code on the DSP. The DSP and Linux sides will interact over DSP/BIOS link.

My questions are:

What is the highest frequency at which my DSP-side code can toggle a GPIO line?
If I want to toggle multiple GPIO lines at this hight rate, how fast can I go?

Thanks for any insights.

I have a video phone application running on OMAP 3530 board.The problem is when i connect the camera(pro 9000) through a powered USB hub (Inp:100to240v, OUT:5v,1A) everything works fine when I make a video call.But If i connect the camera directly to the OMAP3530 board and try to make a video call… >>> More
