To build an advanced micro-process one should start from a basic one. Then build on top of that. This project will serve that purpose. It will help for research and development of a personal line of thoughts for processors.
The basic processors will be taped out and, obviously used in simple consumer electronics. Future developments will cater to complex application. There is no intention to copy or mimic any existing processor.
This is simple microprocessor. Instruction Set Architecture (ISA). The data bus is 16 bit wide. Address bus is 12 bit wide. The instructions are like old 8086 uP. Targeted for calculator, display board and small application.
