The chipset refers to the custom integrated circuits designed by Commodore that formed the heart of Amiga computers, handling graphics, sound, and direct memory access independently of the CPU. The original Amiga chipset evolved through three major generations: OCS (Original Chip Set), ECS (Enhanced Chip Set), and AGA (Advanced Graphics Architecture), each offering improved graphical capabilities and memory addressing. These custom chips—Paula for audio and disk control, Agnus/Alice for blitter and DMA, and Denise/Lisa for video output—enabled the Amiga's advanced multimedia capabilities that outperformed many contemporary systems.
