Hi Muzamil, There is one object that buffers transactions and already has support for prefetches: the cache. Kidding aside, is there any particular reason you don’t want to use the cache? It ticks all the boxes, and avoids adding yet another buffer in the path to memory.

Just to make sure, adding a new SimObject means to create memory side prefetcher from the scratch, (as you explained in your book, creating python files to declare object and its parameters, header files and source file to explain functionality in detail)? Is there any buffer (or simple memory object) class available to instantiate and use it in my config file instead of going all the way around to create a whole new buffer? Any "shortcut" to come-up with the solution of this scenario?

You can either insert it in the interconnect between the LLC and the memory controller (e.g., as a MemObject), or you could make it a parameter to the crossbar like the probe filter.
