SMI Graphics Controllers

Silicon Motion offers two embedded graphics product lines, embedded GPU and server GPU. The embedded GPU product line targets embedded and consumer applications such as high resolution handhelds, point-of-sale terminals, medical equipment, multi-functional printers, casino gaming machines, industrial PCs, and servers. While the server GPU products provide a standard VGA GPU solution for x86 and PowerPC based platforms via PCI, AGP, and PCIe bus interfaces. Our products offer best-in-class performance in terms of power consumption, dual display, and hardware rotation, as well as a ReduceOn™ feature, which is an intelligent power management core that can algorithmically vary the clock of functional units while disabling unused units, resulting in dramatic reduction in average operating power usage without compromising multimedia quality or performance.
