Problem $2(35$ points$)$ A computer system has a $16-$bit address bus, an $8-$bit data bus, and control signals READ and WRITE. The CPU for this system uses isolated I$/$O and also has control signal IO$/$M$\text{'}$ that is $1$ for I$/$O operations and $0$ for memory operations. Its memory subsystem has $8$K x $8$ of ROM starting at address $0000$H constructed from $4$K x $4$ chips; and $4$K x $8$ of RAM starting at address $2000$H constructed using $2$K x $8$ chips. Show the design for the memory subsystem.
