Agnus is the name of a range of custom chips that were featured in the Amiga home computer. The Agnus and Denise chips collectively formed the OCS/ECS chipsets.
Agnus was responsible for
- Providing DMA for sound and graphics
- Handling memory (Memory that can be accessed by the processor and the chipsets)
- Video timing
- The logic for the copper and blitter coprocessors.
Agnus was replaced by Alice in the A4000 and A1200 when the AGA chipset was introduced.
