Hi everbody, I'm new in this forum and currently i'm working with AT91SAM7X ARM processors.

I'm trying to stream video using VLC player or our encoders and this signal is connected in PMY DP83848C and this to AT91SAM7X. I made a code in C++ with a while loop that negates one output everytime it starts this while loop. Besides this the processor is doing nothing more. See below this part of code:
while(1){
AT91F_PIO_SetOutput ( AT91C_BASE_PIOA, NWR );
AT91F_PIO_ClearOutput ( AT91C_BASE_PIOA, NWR );
}

The problem is using even using this routine the frequency is about 700kbps and my plan is to use the Ethernet. To do this I need a clock of a lot more than this because I convert this IP/UDP signal to SPI (Synchronous Parallel Interface) with 32 Mbps.

Can anyone have a idea if i can make this processor quicker? I'm using a 18MHz oscilator.

Thanks,
Gustavo

Hi Gustavo

See the following for a discussion of Ethernet through put speeds:

The maximum SPI speed on the SAM7X is 16MHz so I don't know that it is suitable for your requirements.
