Line 16: == Technical details == In order to increase memory bandwidth, the [[Chip RAM]] data bus was extended to 32-bit width (as in the [[Amiga 3000\|A3000]] (unlike AGA, the A3000's Chip RAM is 32-bit for CPU access only) and the Alice chip (replacing [[Original Chip Set\|OCS]]/[[Amiga Enhanced Chip Set\|ECS]] [[MOS Technology Agnus\|Agnus]]) was improved to be able to support full width access for bitplane DMA. Additionally, the memory clock was doubled. Lisa (replacing former [[Original Chip Set#Denise\|Denise]]) adds support for 8-bit bitplane data fetches, 256 instances of 24-bit palette registers, and for 32-bit data transfer for bitplane graphic and [[Sprite (computer graphics)\|sprites]]. The rest of the chipset remains unchanged, as ~~did~~do the Blitter and Copper coprocessors in Alice, still working on 16-bit data. == See also ==
