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 processor is also known as the Quad Core HD processor. Announced 20 September 2007. [1]
The SpursEngine is a stream processor powered by four Synergistic Processing Elements (SPE), [2] 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 [2] (in contrast to the Cell processor which has an 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. [2]
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%. [3] The resulting chip consumes 10-20 W of power.
The SpursEngine is accessible to the developer from a device driver developed for Windows and Linux systems. Software supporting the SpursEngine is limited and is primarily in the realm of video editing and encoding. [4]
The first generation of SpursEngine processors are specified as follows:
In April 2008 Toshiba shipped samples of the SpursEngine SE1000 device, a PCIe-based reference board. [5]
Toshiba included the SpursEngine processors in their Qosmio laptops, models F50, G50 and G55, in the third quarter of 2008.
