Sega Aurora is a highly integrated hardware platform that Sega Sammy developed to power amusement devices like their pachinko/pachislot machine displays and arcade games and to also be sublicensed to outside manufacturers who are looking to build multimedia portable and embedded systems. It was introduced in 2004 and is primarily based on an enhanced Dreamcast hardware. The name "Aurora" derives from a top secret code name that Sega of Japan used during the development of Sega Saturn in the mid 1990s.
Aurora is made of a Renesas System-on-Chip named SH3707 which incorporates the technologies of partner companies that worked on the Dreamcast and related systems. Its CPU core is Renesas SH-4 based technology with FPU clocked at 300 MHz. Its GPU core is a PowerVR MBX accelerator with VGP co-processor running at 150 MHz. On-chip audio and video hardware supply the system with the capability for ADPCM and MPEG1/2/4 respectively.
