CFD-16 Instruction Set Architecture

CFD-16 is an Instruction Set Architecture designed for a processor of the same name. The ISA is based on RISC principles and has a 16-bit datapath and a 24-bit address space. The architecture does not provide for virtual memory, instead using protected segments to disallow user processes from accessing kernel resources.
