Commercialization

In April 2008 Toshiba shipped samples of the SpursEngine SE1000 device, a PCIe-based reference board. * The accelerator card connects to a 1x PCI Express bus and has 128MB XDR DRAM with 12.8GB/s bandwidth. * Leadtek is producing the WinFast PxVC1100 and HPVC1100, internal and external PCIe accelerators based on the SE1000 platform. * Thomson-Canopus has announced the Firecoder Blu, a PCIe accelerator based on the SE1000 platform.Thomson-canopus.jp
Toshiba included the SpursEngine processors in their Qosmio laptops, models F50, G50 and G55, in the third quarter of 2008.
