The term frame buffer is thus often used interchangeably when referring to this RAM. The CPU sends image updates to the video card. The video processor on the card forms a picture of the screen image and stores it in the frame buffer as a large bitmap in RAM. The bitmap in RAM is used by the card to continually refresh the screen image. [15]
In DOS memory management, the upper memory area (UMA) is the memory between the addresses of 640 KB and 1024 KB (0xA0000–0xFFFFF) in an IBM PC or compatible. IBM reserved the uppermost 384 KB of the 8088 CPU 's 1024 KB address space for BIOS ROM , Video BIOS , Option ROMs , video RAM, RAM on peripherals, memory-mapped I/O , and obsoleted ROM ...
HP 3000 Series III. The HP 3000 series [1] is a family of 16-bit and 32-bit minicomputers from Hewlett-Packard. [2] It was designed to be the first minicomputer with full support for time-sharing in the hardware and the operating system, features that had mostly been limited to mainframes, or retrofitted to existing systems like Digital's PDP-11, on which Unix was implemented.
Up to 15 bpp for Archimedes and Falcon (12 bpp for TT), but typically 4 bpp in use. SVGA: Super Video Graphics Array An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was ...
One southbound frame carries 98 payload bits and 22 CRC bits. Two payload bits are a frame type, and 24 bits are a command. The remaining 72 bits may be either (depending on the frame type), 72 bits of write data, two more 24-bit commands, or one more command plus 36 bits of data to be written to an AMB control register.
The remaining 384 KB beyond the conventional memory area, called the upper memory area (UMA), was reserved for system use and optional devices. UMA was used for the ROM BIOS, additional read-only memory, BIOS extensions for fixed disk drives and video adapters, video adapter memory, and other memory-mapped input and output devices.
