Develop a practical architecture $($targeting specific field$($s$)/$application$($s$))$ with

illustrative instruction and data formats, instruction sets, etc., and a short program $($atleast$,$ with fourteen data entry from a keyboard, data storage to three memory locations $($one peripheral and two network storage units$),$ two unique instructions for the targeted application with full justification, and the $$maximum$$ value calculation of the received data$)$ to quantitatively compare the three cache mapping algorithms. Indicate the corresponding run$-$time register contents and justify all architectural, organizational, etc., selections sufficiently.
