SYSTEMS ARCHITECTURE - LeFreq/Singularity GitHub Wiki
Systems architecture is architecting a system to not only provide general purpose computing, but natural constructs for building complex systems. STUB Subprocessors need device addresses for reading/writing downstream, while also need device lines for writing/reading upstream to other (sub)processors, so not to tax the CPU. Subprocessors should be seen as points in a graph.
OOD (out-of-date): Consider: A square inch can hold about 24 characters of readable data. Translated into physical space a 96Gb machine would be like a chalkboard a square-mile large.
Every device should be addressable with a word-sized (minus 2-bits?) IDentifier (8-16bit (top bits assumed: electronic device, subcomponent) type, manufacturer, model, version, etc.), word-size data in and out, and a word-sized state (get state and set state). The minus 2-bit question is to suggest that one I/O word-sized data bus is used to both command and get/recv data.
