Hey Grackle! Good to hear of your progress
Ah ok, I'm with you now. That does sound elegant.The "caching" idea is that you can take a more relaxed approach: the Prop needs to grab one or two K inside of every 1/60th of a second window, but it could do it by, say, halting the CPU *once* and doing the transfer in one big chunk at the end of every vertical refresh cycle.
Sound more like a My First XTerm to me - one device to handle the whole UI.The cool thing about the Propeller, of course, is it's a fully general purpose CPU so in theory you could order it to do things like line/circle drawing, vectors, etc. (Also, you could wire a mouse to the Propeller and let the Prop completely handle the cursor generation, tracking, and even some of the high-level aspects of a GUI like window drawing and text handling. Think of it as a sort of Fisher-Price My First NeXT.)
This is ... interesting.Or you could try driving an ISA video card.
This too.maybe make a single board computer with just a serial port for a console to start with. If you expose the CPU bus on an expansion connector, you can interface anything you like to it later on.
