Calling process of second module from first module process

[Ahr]

I have a module which shapes the data and then dump into the memory module depending on if data input is more than Bandwidth. If data input is less than Bandwidth then it will bypass it that means no clock cycle wastage and the way to bypass is only if I can call the process of memory module from shaper module for writing the data.

So, is it possible to do what I am thinking? or I can do the bypassing without calling the process of memory module?
