64bitPCille
64bitPCille is a fictional 64-bit personal computing platform introduced for educational and speculative discussion of modern computer architecture. It describes a complete stack including an instruction set architecture (ISA), a reference implementation, and a software ecosystem used in textbooks and classroom exercises to illustrate architectural trade-offs in 64-bit systems.
The architecture of 64bitPCille centers on a 64-bit address space and 64-bit general-purpose registers. It employs
Software on 64bitPCille includes a reference operating system called 64PCOS and a minimal standard library. The
64bitPCille has had limited practical adoption and remains primarily a teaching tool. It appears in curricula,
