With the Megas being "old technology" now, and the Atari blitter being
at least a reasonably well known thing. Could someone who really knows
what this thing can do describe it? If you are aware of other blitters
(Xerox, Commodore) could you compare them?
Some of the questions I am particularly interested in :
- Does the blitter have a barrel shifter to do bit aligned
transfers?
- What restrictions are there are arbitrarily aligned rectangles
if any?
- What logical operations does it support? Are any of them numeric
such as T.I.'s PixBlt stuff?
- How do the blitter and 68000 get along, especially on the memory
bus?
- How fast is it? How many clocks/byte does it transfer?
- How many sources/destinations does it support?
- How much does it affect overall system performance?
Any info appreciated,
