"Computer architecture" is used in several different ways and that can lead to some very confusing conversations. Your proposed stack has some of this confusion. Some alternative terms might help: "computational model": finite state machine, Turing machine, Petri nets, data-flow, stored program (a.k.a. Von Neumann, or Princeton), dual memory (a.k.a. Harvard), cellular automata, neural networks, quantum computers, analog computers for differential equations "instruction set architecture": ARM, x86, RISC-V, IBM 360 "instruction set style": CISC, RISC, VLIW, MOVE (a.k.a TTA - Transport Triggered Architecture), Vector "number of addresses": 0 (stack machine), 1 (accumulator machine), 2 (most CISCs), 3 (most RISCs), 4 (popular with sequential memory machines like Turing's ACE or the Bendix G-15) "micro-architecture": single cycle, multi-cycle, pipelines, super-pipelined, out-of-order "system organization": distributed memory, shared memory, non uniform memory, homogeneous, heterogeneous With these different dimensions for "computer architecture" you will have different answers for which was the weirdest one.
