is found in the kernel driver (/dev/cedar_dev) source code where it has been directly referred to as 'cedar engine' in error/information messages and internal variables. Take note that this is the kernel driver that was made for the proprietary libraries that already existed in Melis OS, were the media player application goes by the name 'cedar'.

• MACC - Media ACCelerate video engine

is also found in the kernel driver and respective headers, where the mmio area (registers) is referenced by macc as a prefix for the definition of the register base address.
