<h1>Build a multiplexer!</h1>
|
||
|
|
<p>
|
||
|
|
The multiplexer chip used in this CPU is a <b>16:8</b> mux - this means it can select between <i>two</i> <b>8-bit</b> inputs.</p><p>
|
||
|
|
Don't worry, this is an extremely simple chip to construct. To start with, you must build from logic gates a <b>2:1</b> mux which can switch between two individual bits. Then you can use 8 of these <b>2:1</b> muxes to build this chip.
|
||
|
|
</p>
|
||
|
|
<!--<p>
|
||
|
|
You will also need a <i>demultiplexer</i> for later use. This chip, instead of choosing between inputs, takes a fixed input and instead selects between multiple <i>outputs</i>.
|
||
|
