Hello, Has anyone implemented synchronous sram for Nios instruciton and data store (ie execute out of synch sram)? I'm sure it can be done, but I'm wondering about the performance hit ...

21 years agoHello,
I think Avalon will present the address/control in one clock. The thing to look at is the timing diagram for the synch ram for an opening access (ie new address). The last parts I used required 3 clocks for an opening access or an address change. After that, an internal address counter takes over, and the device spits out data on every clock. If you move to another non-sequential location, another 3 clocks delay. Your parts may not work this way. Eric
