Alliance Semiconductor ProMotion 6422

Alliance's ProMotion-6422 is a high-performance, 64-bit integrated Windows accelerator with built-in hardware acceleration for MPEG-1 motion video playback and scaling. It is a fully software-compatible member of Alliance's ProMotion family of graphics and video accelerators. ProMotion controllers are designed to seamlessly accelerate graphics and multimedia applications under Windows 95, Windows 3.x and other operating environments.

ProMotion-6422 accelerates Windows displays up to 1280x1024 resolution at 8 bits per pixel (hardware, graphics) bits per pixel - (bpp) The number of bits of information stored per pixel of an image or displayed by a graphics adapter. The more bits there are, the more colours can be represented, but the more memory is required to store or display the image. , and up to 800x600 resolution at 24 bits per pixel truecolor, for displays up to 16.7 million colors. It features a 64-bit internal graphics engine, PCI local bus host interface, and support for 1 to 4 megabytes of DRAM memory. Even with only 1 megabyte of display memory, it can accelerate full-screen, 1024x768x8-bit or 800x600x16-bit graphics and motion video playback.
