Taiwan-based Silicon Integrated Systems (SiS) announced the release of its latest PC compatible system-on-chip (SOC) processors today. Compared with earlier devices in the 55x family, the SiS550 LV and SiS552 LV feature higher performance yet lower power consumption, SiS said. Additionally, both new high-integration x86-architecture SOCs support operation under a choice of either Linux or Windows… operating systems.

SiS says it is targeting the SiS55x LV family at the “embedded information appliance (IA) market,” which is said to include nonportable applications such as thin client servers, set-top-boxes, kiosks, and intelligent process control, as well as portable apps such as electronic books, webpads, and PDAs.

Both the SiS550 LV and SiS552 LV include a 250MHz x86 CPU (MMX compatible), North Bridge, South Bridge, DRAM controller, “Ultra-AGP” VGA, sound, software modem, and CIR controller. In addition to these, the SiS552 LV adds controllers for Smart Card, Sony Memory Stick, Slice layer DVD Decoding accelerator, Video Input Port, and Consumer Digital Audio Interface.

According to SiS, the new SiS55x LV SOCs achieve better than a 55% reduction in power consumption, yet provides a 25% increase in CPU performance, compared with earlier chips in the family. In case you were wondering, the “LV” stands for “lower voltage.”
