1)Develop a hypothetical architecture with illustrative instruction and data formats, instruction sets, etc., explain the instruction and machine cycles step-by-step by developing a short program (at least, with three arithmetic operations, two logic operations, two memory or three I/O operations) and by indicating the corresponding register operations. All architectural, etc., selections must to be justified sufficiently.

2) Develop a hypothetical architecture with illustrative instruction and data formats, instruction sets, etc., and a short program (at least, with six data entry from keyboard, data storage to two memory locations, and the average value calculation of the data entered from the keyboard) to compare the three cache mapping algorithms. Indicate the corresponding run-time register contents and justify all architectural, etc., selections sufficiently
