Ubicom was a San Jose, CA-based company which developed communications and media processor (CMP) and software platforms for real-time interactive applications and multimedia content delivery in the digital home. The company provided optimized system-level solutions to OEMs for a wide range of products including wireless routers, access points, VoIP gateways, streaming media devices, print servers and other network devices. Ubicom was a venture-backed, privately held company with corporate headquarters in San Jose, California.

History
Ubicom was founded as Scenix Semiconductor in 1996. The company operated under that name until 1999. In 2000, Scenix became "Ubicom," a word derived from "ubiquitous communications".
Products
Ubicom (and as Scenix) designed several families of microcontrollers, including:
The Scenix/Ubicom processors relied on very high speed and low latency processing to emulate hardware interfaces in software such as interrupt-polled soft-UARTS. This reduced the size of the silicon chip and therefore the cost, but increased the complexity of the software required on the chip.
Ubicom developed its own architecture, the Ubicom32™, and a real-time operating system (RTOS) for it. For example, the D-Link HD Media Router 3000 DIR-857 contains the Ubicom IP8000AU and the Western Digital WD N900 the Ubicom IP8260U CPU. The firmwares are most probably Linux-based, maybe even OpenWrt-based, rather than Ubicom RTOS-based.
Logging in via telnet on a Western Digital N900, the CPU is known as:
