Honored ContributorAbout SDRAM clock ! ?
Can I use separate clock for SDRAM ? For Example CPU- 50 MHZ SDRAM - 100 MHZ Is it possible ?

Honored ContributorWhat I wanted to do was to run a NIOS core at 50MHz and VGA from the same SDRAM block. I don't want the NIOS to add wait states. Sitting with 133MHz (100Mhz from the core) memory seems a waste. So I want to run my 50Mhz NIOS at 50MHz, with the best memory performance, and use the rest of the bandwidth for something else.
Will try and add some more delay. Thought the 72 degrees would be enough. Will play with that. My thought was that the avalon bus would handle everything. Seeing that you can run 2 or more NIOS CPUs from the same memory, running at the same speed it makes sense that running 2 or more CPUs/masters from faster peripheral (like 100MHz SDRAM) would be possible.
