​ KembaraXtra-Computer Terms – blitter:
A blitter is a graphics function or hardware component responsible for copying bitmap images from memory to the display screen. It performs this task quickly so that graphical elements such as icons, sprites, or text can be displayed efficiently.
Blitters are often used in graphical systems and video hardware to accelerate drawing operations. By handling bitmap transfers directly, they reduce the workload on the main processor and improve the performance of graphics-intensive applications.
