What CPU does CD-i use?
A CD-i player is equiped with a Motorola 68000-like processor, similar to the ones used in the original Apple Macintosh, Atari ST and Commodore Amiga. All Philips CD-i players used a Philips-build 68070, which differs from the 68000 in that way that it had some port controlling features build in. The processor runs at 15 MHz. According to the Green Book, the 68000-CPU should at least have a 16 bit external data path, and a 32 bit internal data path, very similar to Intel’s 80386SX processor. The CD-i standard allows for a faster CPU, but since CD-i’s performance is almost entirely based on the realtime retrieval of audio and video data from the disc, the performance will not be raised that much when a faster CPU is used. This is why CPUs in all CD-i players build to date are based on the minimal Green Book requirements. 3.3 What OS does CD-i use? The operating system used in a CD-i player is called CD-RTOS, which stands for Compact Disc Real-Time Operating System. It is hard coded in a
