This is a repo of the project in the book The Elements of Computing Systems.
These projects below are the ones had been finished:
using the Nand gate and the composite gates that build on top of it to implement the other gates, such as the And gate , the Not gate , the Or gate , the Xor gate , the Multiplexor and the Demultiplexor in different ways and bit-width.
using the gate built in the formal units to imply the combined logical circuit like the half-adder, the full-adder, the 16-bit adder, the 16-bit increaser, and finally the ALU.
using the Data flip-flop(DFF) to build sequential logic circuit and joint them with combined logical circuit, and imply the circuit like the Bit-register, the register, the n-bits RAM and the n-bit counter.
