[comp.graphics] How does BitBlt work?

jinli@gpu.utcs.utoronto.ca (Jin Tonic Li) (08/28/89)

Could someone tell me how the BitBlt microcode on the Xerox Alto and the 32-bit
barrel shifter on the original(I think newer Suns do not use it any more) Sun
workstation work?  They are supposed to increase the performance of scan
conversion.

Thank you in advance.
