nand2tetris

An implementation of the projects described at https://www.nand2tetris.org.

The different folders correspond to different tasks outlined below:

• Tasks 01 to 05: Implementing a complete CPU ISA with the primitive NAND gate and the primitive flip-flop. This was done in HDL.
• Task 06: Building an assembler for that ISA.
• Task 07: Designing a virtual machine, and it's bytecode interpreter
• Task 11: Designing an OOP language, and writing a compiler that turns it into the VM's bytecode.
• Task 12: Designing an operating system in this language.
• Task 09: Writing a graphical Sudoku game for that operating system, in the designed language.

The computer facilitated screen and keyboard usage using memory-mapped I/O. The assembler, interpreter and compiler were written in Typescript.
