there is blockram instantiated in my zpu_core.vhd. does this decoder take out one by one the data in the blockram(in attachment)??

I can't say. You will have to simulate the design and verify. The decoder is meant to decode the addresses of the processor not that of a memory. A good reading of processor basics should clear your doubts:

can you give me examples of chip_select??

Some good examples can be the select lines of a mux, enable lines of a counter and CS signals of external memories.

No. The address should be that of a processor.
