How to search for upcoming conferences for Hardware Architecture? How to find upcoming conferences in a specific field? I can get some references from answers to this question. 

I had already tried WikiCFP but it deosn't have the option to filter CFP's according to the subject. The other options such as (How to find upcoming conferences in a specific field? I can get some references from answers to this question. 

The other options such as ACM Calender of Events but this also has no classification.

Any pointers on where to search will be very helpul.
WikiCFP does have an option to filter by subject: go to the "Categories" option and you will find a list of keywords such as "Computer Architecture" that will give you listings of all of the CFPs in that subject.
