Develop a practical architecture (targeting specific field(s)/application(s)) with illustrative instruction and data formats, instruction sets, etc., and a short program (at least, with twenty-three data entry from a scanner, data storage to two memory locations (one peripheral and one network storage), one unique instruction for the targeted application with full justification, and the average 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.
