The Video Buffering Verifier (VBV) is a theoretical MPEG video buffer model, used to ensure that an encoded video stream can be correctly buffered, and played back at the decoder device. By definition, the VBV shall not overflow nor underflow when its input is a compliant stream, (except in the case of low_delay).
Verilog-2001 is a significant upgrade from Verilog-95. First, it adds explicit support for (2's complement) signed nets and variables. Previously, code authors had to perform signed operations using awkward bit-level manipulations (for example, the carry-out bit of a simple 8-bit addition required an explicit description of the Boolean algebra ...
The VGA text buffer is located at physical memory address 0xB8000. [14] Since this address is usually used by 16-bit x86 processes operating in real-mode, it is also the first half of memory segment 0xB800. The text buffer data can be read and written, and bitwise operations can be applied. A part of text buffer memory above the scope of the ...
An on-chip FIFO buffer for both incoming and outgoing data; this gives the host system more time to respond to an interrupt generated by the UART, without loss of data. Both the computer hardware and software interface of the 16550 are backward compatible with the earlier 8250 UART and 16450 UART .

It is a standard feature for a UART to store the most recent character while receiving the next. This "double buffering" gives a receiving computer an entire character transmission time to fetch a received character. Many UARTs have a small first-in, first-out buffer memory between the receiver shift register and the host system interface. This ...
In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. [3] The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. [4] Screen buffers should be distinguished from video memory.
Verilog-A is an industry standard modeling language for analog circuits. It is the continuous-time subset of Verilog-AMS . A few commercial applications may export MEMS designs in Verilog-A format.
