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.
This tape-out includes 8KB on-chip openram. Capability added to load RAM with programs via logic analyser bus of caravel. The chip will be 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 bits wide. Address bus is 12 bits wide. The instructions are like old 8086 microprocessors. This tape-out has 8KB on-chip RAM. Targeted for calculator, display board and small application.
