Design a CPU 2

In this course we take what we learned from the first course and expand on the simple 8 bit design and create a 16 bit machine with a maximum of 64 instructions with each instruction having access to 4 different addressing modes. We cover port mapped i/o and memory mapped i/o. We start using a new faster more stable version of Logisim.
The hard wired control unit is replaced with a mixed hardwired and microcoded control unit. We increase the number of general purpose registers from 4 to 6 and add in a temporary register, index register , stack pointer register and floating point unit register.

We design a new assembler in python to help us write the assembly language code with our new larger instruction set.

Finally we add on a keyboard a character display and a graphics display.

The 64 Kbyte address space is split into a ROM that contains the start of an operating system and commonly used subroutines and a RAM that contains the program code and data.
If you want to know how to build a fully functioning 16 bit machine and design some cool assembly language programs then this is the course you need to take.

Don't just read about theory and imaginary machines , build an actual machine that works. It's the best way of learning Computer Architecture Design and Organisation.
