  2. Upper memory area - Wikipedia

    en.wikipedia.org/wiki/Upper_memory_area

    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 ...

  3. Framebuffer - Wikipedia

    en.wikipedia.org/wiki/Framebuffer

    A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame . [ 2 ]

  4. Stack-based memory allocation - Wikipedia

    en.wikipedia.org/wiki/Stack-based_memory_allocation

    Stack-based allocation can also cause minor performance problems: it leads to variable-size stack frames, so that both stack and frame pointers need to be managed (with fixed-size stack frames, the stack pointer is redundant due to multiplying the stack frame pointer by the size of each frame).

  5. Linux framebuffer - Wikipedia

    en.wikipedia.org/wiki/Linux_framebuffer

    Knoppix booting on the framebuffer. The Linux framebuffer (fbdev) is a linux subsystem used to show graphics on a computer monitor, typically on the system console. [1]It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and ...

  6. Flow control (data) - Wikipedia

    en.wikipedia.org/wiki/Flow_control_(data)

    Sliding-window flow control is best utilized when the buffer size is limited and pre-established. During a typical communication between a sender and a receiver the receiver allocates buffer space for n frames (n is the buffer size in frames). The sender can send and the receiver can accept n frames without having to wait for an acknowledgement ...

  7. Graphics processing unit - Wikipedia

    en.wikipedia.org/wiki/Graphics_processing_unit

    In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scanned out on the monitor. [ 1 ] A specialized barrel shifter circuit helped the CPU animate the framebuffer graphics for various 1970s arcade video games from Midway and Taito , such as Gun Fight (1975), Sea Wolf ...
