Use MIPS memory-mapped I/O to interact with a user. Each time the user presses a button, a pattern of your choice displays on five light-emitting diodes (LEDs). Suppose the input button is mapped to address 0xFFFFFF10 and the LEDs are mapped to address 0xFFFFFF14. When the button is pushed, its output is 1; otherwise, it is 0.
(a) Write MIPS code to implement this functionality.
(b) Draw a schematic for this memory-mapped I/O system.
(c) Write HDL code to implement the address decoder for your memory-mapped I/O system.
