The second part is awesome too. The first part shows how to design an unoptimized and simplistic, but complete and working 16-bit CPU and RAM from logic gates.

The second part is awesome too. The first part shows how to design an unoptimized and simplistic, but complete and working 16-bit CPU and RAM from logic gates. The second part builds a whole software stack on top of it using a virtual stack-based VM: - CPU assembler; - a (AOT) compiler from the VM opcodes into the CPU assembly; - a compiler from the high-level language called Jack (an educational mix of Java/C with many complex parts removed) into the VM opcodes; - a standard library for the Jack language (Screen/Keyboard/Output/Math/String/Array/ Sys/Memory classes), including writing your own memory allocator and drawing lines/circles and bitmapping glyphs into video memory for text rendering; - your own project (usually a simple game and sometimes marvels like [0]) written in Jack on top of all of that; The courses are definitely very challenging and some previous exposure to the topics is desired.
