What are the typical functions/acceleration that this type of GPU supports other than the blitter mentioned in the post? I'm very surprised to see so few chips

I'm very surprised to see so few chips being used; doesn't 7400 logic only give you ~4-8 gates per chip?!?
- niklasni1 11y agoThe 74-series is not just plain gates, there are multiplexers, latches, counters, adders, and even complete ALUs.
- peterfirefly 11y ago+ shift registers, amplifiers ("bus drivers"), tri-state thingies, carry generation circuits (for faster ALUs, especially when you connect several ALU chips together for wider additions).
- cmrdporcupine 11y agoI believe his GPU (or VDP in the old terminology, GPU seems more specific to 3D coprocessors) can do horizontal and vertical scrolling and 100 sprites.
