BLITTER Meaning and
Definition
-
A blitter is a specialized hardware component or subunit in computer systems responsible for performing fast and efficient block transfer operations, primarily used in older generations of computer graphics. Derived from the term "bit blit" (bitmap block transfer), a blitter is designed to directly manipulate blocks of data, typically graphical images or video frames, within computer memory.
The blitter's functionality revolves around two primary operations: bitblt and bitblk. Bitblt, short for "bit block transfer," involves copying a rectangular block of pixels from one location in memory to another, allowing efficient pixel-level manipulation for various graphic operations, such as scrolling, window resizing, or drawing shapes. Bitblk, on the other hand, performs a similar function but instead allows for the transfer of pixels between two areas with an optional logical operation performed on the data during the process (e.g., logical AND or XOR).
Blitters provide significant advantages in terms of speed and efficiency over more general-purpose mechanisms, such as the CPU or the GPU. By offering hardware-accelerated operations specifically tailored for block transfers, blitters can offload heavy computational tasks from the CPU, reduce memory bandwidth requirements, and enhance overall graphical performance, making them particularly useful in retro gaming consoles, arcade machines, or early personal computers.
However, with advancements in graphics technology, the need for dedicated blitters has diminished, as more powerful CPUs and GPUs can handle block transfers efficiently without specialized hardware. Hence, blitters have become less prevalent in modern computer systems.

Etymology of BLITTER
The term "blitter" is a portmanteau of the words "bit" and "blit". "Bit" is short for "binary digit", the basic unit of information in computing, while "blit" is an abbreviation of "block transfer". The word "blit" itself originated in early computer graphics and video game development.
The "blit" operation refers to a fast method of transferring a large block of data directly between two areas of memory. This technique is commonly used in graphics and video processing to quickly move and manipulate images.
In the context of computer graphics, the "blitter" is a specialized hardware or software component responsible for performing this block transfer operation. It gained popularity particularly during the 1980s and 1990s with the rise of arcade games and home computers.
