Akiko (Amiga)

Akiko (Amiga)

Akiko is a custom chip used in the Amiga CD32 games console and forms part of the AGA chipset used in that system.

The Akiko chip performs 'chunky' to 'planar' graphics conversion in hardware. The Amiga's native display is a planar display which is simple and efficient to manipulate for routines like scrolling. However, chunky displays are faster and more efficient for 3D graphics manipulation. Akiko allowed this conversion to be performed in hardware instead of relying on software conversion which would otherwise slow the system down.

Akiko is also responsible for implementing some of the control logic for the CD32's CD-ROM controller, as well as for controlling the serial ('AUX') port [cite web|title=The Big Book of Amiga Hardware - Custom Chips: Akiko|url=http://bboah.amiga-resistance.info/cgi-bin/showhardware_en.cgi?HARDID=1449] .
