Simple emulator of the Intel 4004 chip.
The Intel 4004 was the first computer that I made an emulator, unfortunately I lost the code. Since then I have been studying and assembling small emulators and studying the architecture of computers and embedded devices. After a long time I am going back to the emulators, and the first one that I will focus on development is the Intel 4004, because it is a simple device with a few instructions (46 instructions).
## Intel 4004
Intel 4004 is a 4-bit CPU released by Intel in 1971, which was the first commercial programmable microprocessor.
## Compile
Inside the root dir of the project.
```sh
mkdir build && cd build
cmake ..
make
```
That create the executable ```4004_emulator```.
