Emotion Engine Emotion Engine is the name of the Central Processing Unit (CPU) used in Sony PlayStation 2 video game consoles. It was jointly designed by Toshiba and Sony and began mass production in 1999. According to MicroDesign Resources, it is two times faster than a 733 MHz Pentium III and 15 times faster than a 400 MHz Celeron at handling tasks like full-motion video. The Emotion Engine's data bus, cache memory as well as all registers are implemented in 128 bit technology, integrated on a single 0.18 micron process technology chip (making it the first commercial 128 bit CPU). The Emotion Engine, based on the MIPS R5900, is sort of a combination CPU and DSP processor, whose main function is simulating 3D worlds. It integrated all necessary units on the die: The MIPS III CPU core, 2 vector units, FPU, image processing unit (basically an MPEG2 decoder with some other capabilities), 10-channel DMA controller, graphics interface unit, RDRAM and I/O interfaces, all connected via a shared 128-bit internal bus.
