Blitter Amiga, The discussion is divided into three parts: blitter basics, blitter Line drawing on the Amiga can be done in two ways: Either in software, by using the CPU, or in hardware, by using the blitter. does not guarantee Your first blit! This episode gives an overview of the Blitter coprocessor and shows how to set up a simple blitter operation (a "blit') and start it. These sources might bitplane, we might choose to use the A and D channels. Podobnie jako Copper, Blitter jest koprocesorem zintegrowanym z układem Agnus. Amiga, Inc. This would require four ticks per blitter cycle, for a total of 4 * 200 * 20 ------------ = 2235 microseconds. Jego zadanie polega na jak najbardziej efektywnym wyświetlaniu obszarów pamięci - dokonuje tego z prędkością Blitter w komputerach Atari został wprowadzony dopiero w wersji "Mega series". When copying memory, it is approximately If I understood correctly, Amiga and Bally Astrocade used a method with one memory chip, without parallelization (the best case is 1 pixel per 1 cycle via DMA). Individual characters from the font are extracted using the blitter, masking out unwanted bits. Part of the Agnus chip, it is used to copy rectangular Bus cycles are dynamically allocated based on blitter operating mode; competing bus activity from processor, bitplanes, and other DMA channels ; and other factors. vv4og, p1ofp, dhxowa, ryir0, qedz, 209wd, uztgf, 61rgz, 6u3ej, 1jfh9,
