21 years agoHello, here are some answers.
1) You can have both using the Flash memory but I don't recommend it (see answer 2) 2) SDRAM is relatively fast so I would target your code to it. Now the tricky part, yes you can have both target the SDRAM but you have to be careful with memory allocation (especially the heap and stack). 3) ........ probably easiest to make a single bit PIO for each processor that you write to which generates the interupt (that's going to be very little logic). Then you would just tie interupt line to the opposite processor (I'm guessing you want the interupt to tell the other processor to look at the DP RAM). Here's my suggestion: Using answer 3 and using SDRAM ram for one CPU and a single 64kB onchip memory for the other may get you by. This is the simplest way that I can think of doing this. If this doesn't sound like a good enough solution maybe someone else here can think of something else. If you have more questions for me drop me an email since my viewing of the forum is off and on these days. Cheers, and good-luck http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
