Emotion Engine

The Emotion Engine is the processor ( CPU) of the PlayStation 2 from Sony, the. Still the best- selling game console in the world This CPU was jointly developed by Toshiba and Sony and is based on a MIPS core. The chip was also installed in the first models of the PlayStation 3 in order to realize the these versions still available for backward compatibility to PlayStation 2.

Technology

The chip is based on an extended MIPS R5900 core, on which not only the actual CPU two vector processors ( VU0 and VU1 ) are located. Similarly, an MPEG-2 decoder is on the chip. The processor operates at a clock frequency of 294.912 MHz and has a 16 kb instruction cache and an 8 kb data cache. The internal bus is 128 bits wide and is clocked at 150 MHz. The external DRDRAM is two 16- bit wide buses, which are betaktet 400 MHz, connected. The (theoretical) raw performance of the processor is approximately 6.2 GigaFLOPS ( floating point operations / sec).

On The approximately 10.5 million transistors are in an area of ​​240 mm ². The chip was made ​​by Sony and Toshiba in CMOS process.
