The Emotion Engine was a CPU developed and manufactured by Sony Computer Entertainment and Toshiba for use in the Sony PlayStation 2 video game console. It was also used in early PlayStation 3 models sold in Japan and North America (Model Numbers CECHAxx & CECHBxx), to provide PlayStation 2 game support. Mass production of the Emotion Engine began in 1999 and ended in late 2012 with the discontinuation of the PlayStation 2.
