bitblt การใช้

It included a custom bit-block-transfer ( BitBlt ) graphics processing unit ( GPU ) together with a dual-CPU multiprocessor.
The commands performed BitBlt operations within the frame buffer, between the system memory and frame buffer and were also used to paint characters from the font cache.
The big success of the Series 32000 was in the laser printer market, where the NS32CG16 with microcoded BitBlt instructions had very good price / performance and was adopted by large companies like Canon.
In the 1980s, when bitmapped computer displays became popular, some computers provided specialized bit block transfer ( " bitblt " or " blit " ) instructions to set or copy the bits that corresponded to a given rectangular area on the screen.
L Peter Deutsch, one of the pioneers of the Postscript language, finally found a way to achieve Xerox-Star-like efficiency using just-in-time compilation in the early 1990s for bitmap operations, making the last bit of Xerox-Star custom hardware, the BitBLT, obsolete by 1990.
