[ts-7000] Re: Can I use xdio of ts-7300 as CMOS sensor interface?

Hi, Dave,

  Thank you very much for your excellent advice!
  As you described, there're two devices (FPGA, ARM processor) that 
access the SDRAM. From my understanding, FPGA and ARM processor use 
different SDRAM (8MB for FPGA, 32MB for ARM cpu) and some memory 
space are mapped together. Is my understanding right? 
  Does the wishbone bus act as the arbiter? Or do I need to design 
the arbiter within FPGA? How does the arbiter interact with the ARM 
cpu? 
  Thanks,

  Zhaomin
