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.
• Toshiba said the Satellite Pro 480CDT comes standard with advanced multimedia features such as a 10-speed CD-ROM drive, three-dimensional ( 3-D ) sound support, integrated stereo speakers, large 12.1-inch display with 800 by 600 resolution, HiQVideo PCI graphics controller with 64-bit BitBLT graphics acceleration, zoomed video ( ZV ) architecture, 32-bit CardBus, and the new Universal Serial Bus ( USB ) technology.
• Both adaptors allowed offloading of line-draw, bitmap-copy ( bitblt ), and color-fill operations from the host CPU . XGA's acceleration was faster than 8514's, and more comprehensive, supporting more drawing primitives, the VGA-res hi-color mode, versatile " brush " and " mask " modes, system memory addressing functions, and a single simple hardware sprite typically used to providing a low CPU load mouse pointer.
