How to determine the latency of some DFG operations? #26

Hi Cheng,

Just notice that in the param.json file you let the latency of load/store operations to be 2. How did you get this value?

Thanks.

I just try to make it parameterizable. It could be 1 or any value. But for now, our hardware only support single-cycle memory access.
