Fontes na internet afirmam que a Toshiba prepara-se para reactivar a guerra com o formato Blu-ray. Depois da derrota do HD-DVD a marca nipónica quer superar a humilhação ao introduzir um novo deck DVD com o superchip "Spurs Engine" (baseado no processador Cell) capaz de um inovador super upscalling para resoluções HD.

Segundo a wikipedia :

SpursEngine is a microprocessor from Toshiba built as a media oriented coprocessor, designed for 3D- and video processing in consumer electronics such as set-top boxes and computers.

The SpursEngine is a stream processor powered by four Synergistic Processing Elements (SPE), also used in the Cell processor featured in Sony PlayStation 3. These processing elements are fed by on chip H.264 and MPEG-2 codecs and controlled by an off die host CPU, connected by an on chip PCIe controller (in contrast to the Cell processor which has a on chip CPU (the PPE) doing similar work). To enable smoother interaction between the host and the SpursEngine Toshiba also integrated a simple proprietary 32-bit control core. The SpursEngine employs dedicated XDR DRAM as its working memory.

The SpursEngine is designed to work at much lower frequencies than the Cell and Toshiba has also optimized the circuit layout of the SPEs to reduce the size by 30%. The resulting chip consumes 10-20 W of power.

The SpursEngine is accessible to the developer from a device driver currently in development for Windows and Linux systems.
