what is read/write collision on dualram?
how can it be handled?
why reading and writing from same location is not possible?....
(we can get either old value or new value....knw?)
 

hi
In Xilinx FPGA you can read write from one location simultaneously if you set some additional parameters, as I remember. Problems could occur, because you can read wrong data.
And handled it you should create some additional logic around memory(controller) , of couse if your memory does not implement it already.
