Class of Microcomputers II at a University needs to design a computer system with an 8-bit address bus, an 8-bit data bus and it uses isolated VO. It has
128 bytes of EPROM starting at address 00H (H meaning in hexadecimal) constructed using 64x4 chips;
64 bytes of RAM constructed using 16x8 chips;
an input device with a READY signal at address ABH;
an output device with a READY signal at address CDH;
a bidirectional input/output device with no READY signal at address EFH.
Please show the complete design for this system. (Choose an appropriate starting address for the RAM by yourself, and use a decoder to enable memory chips.) include all enable and load logic.
Evaluating the following components:
(1) Memory chips and structure
(2) Memory chips decoder
(3) Input & outpr.tt devices and their enable logic
(4) Data bus and other wire connections (25% in which 5% is fbr the width of the connection wire between all pairs of components).
