Development in progress

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.

mkdir build && cd build
cmake ..
make

That create the executable 4004_emulator.
