Emotion Engine

The 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 twice the speed of a 733 MHz Pentium III and 15 times the speed of a 400 MHz Celeron at handling tasks like full-motion video (SIMD). [1]

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 micrometer 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.

The chip is also used in early PlayStation 3 units to achieve backwards compatibility. PAL PlayStation 3 units do not include an Emotion Engine as a matter of cost-saving, however this means such units must use less reliable software emulation to achieve some level of backwards compatibility. It is believed that eventually a hardware revision of NTSC units will remove the Emotion Engine chip in these territories.

mais simples que isto é impossível. já agora, porque é que estás sempre a abrir tópicos a fazer perguntas da PS3? ao menos metias tudo no mesmo tópico...
 
... em vez de abrires um tópico novo, vais a um dos que já criaste (como este) e metes a dúvida nova... óbvio, não?
