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
As Scenix and Ubicom, the company designed several families of microcontrollers, including:
* The SX Series of 8-bit microcontrollers, a product line which was partially compatible with Arizona Microchip devices and ran at up to 100 MHz, single cycle. This product was eventually sold to Parallax, who continued its production.
* The IP series of high performance media and Internet processors. These devices were designed to act as gateways for streaming media and data over wired and wireless links.
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
A real-time operating system (RTOS) is an operating system (OS) for real-time applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which m ...
