Memory controller (memory that can be accessed by the processor and the chipset).

25 Direct Memory Access (DMA) channels, allowing graphics, sound and I/O to be used with minimal CPU intervention.

" Copper", a display synchronized co-processor.

The Blitter is capable of copying blocks of display data, or any arbitrary data in the on-board memory, at high speed with various raster operations as well as drawing pixel perfect lines and filling outlined polygons, while freeing the CPU for concurrent tasks. The Blitter and Copper are also contained here.

According to Jay Miner, original Agnus was fabricated in 5 μm manufacturing process like all OCS chipset. The 8361 Agnus is made up of approximately 21000 transistors and contains DMA Channel Controllers.

Its main function, in chip area, is the RAM Address Generator and Register Address Encoder which handles all DMA addresses. The Agnus, Denise and Paula chips collectively formed the OCS and ECS chipsets. The MOS Technology "Agnus", usually called Agnus, is an integrated circuit in the custom chipset of the Amiga computer.
