DDR3 EMIF IP Maximum Theoretical Throughput Data rate inclusive of waitrequest dealy

Hi all, I have tried to find the "Maximum Theoretical Throughput" Data rate for DDR3 EMIF IP using 'Efficiency Monitor'. But, I wanted to know is there any other way, through which we can actua...

Hi Linas,

I was actually observing the 'Waitrequest' signal going high for long time. So, I though the 'waitrequest' plays a main role in determining the 'theoretical achievable maximum throughput'. I also observed that the 'waitrequest' is differing for each writes. Is there any standard measurement to measure this. so, that we can confirm the maximum range the EMIF IP will be working without any issues given that the data is coming at almost equal to DDR Clock.

Also note that, we are using burst mode with burst count as 8.

Thanks,

Gokul
