The roots of SMSC's Automotive Infotainment Systems go back to the early 1990s. It was formerly known as OASIS SiliconSystems, which was acquired by SMSC in March of 2005.

• OASIS Design originated in Austin, Texas in 1993.
  It was established to develop mixed-signal semiconductor integrated circuits used to control and connect automotive multimedia components.
  
  
• SiliconSystems was founded in Karlsruhe, Germany in 1996.
  The company's main focus was on developing system and application framework that provided a common way for software and hardware to be fully integrated. The company also developed the tools necessary to design and verify these interconnected systems.

OASIS Design and SiliconSystems realized the need for a multi-protocol synchronous network when working together on automotive applications for high-end European automakers. The automobile was the first "mobile appliance" where designers looked to expand its on-board entertainment and information systems, and a cost effective solution was needed to enable these components to communicate with one another.

To accommodate these needs, OASIS Design, and SiliconSystems were affiliated in the summer of 1997 by the creation of OASIS SiliconSystems AG. This new parent company, headquartered in Karlsruhe, Germany, united the expertise of these two separate subsidiary companies.

OASIS SiliconSystems began building a strong working relationship with automotive OEMs and suppliers who shared the vision of driving an open standard for networking automotive multimedia systems. Focusing on the technical requirements for this solution, BMW, DaimlerChrysler, Harman/Becker and OASIS SiliconSystems became the founding members of the MOST Cooperation, formed in 1998. The founding members focused on promoting the MOST technology by establishing a partnership between automotive OEMs and key component suppliers in order to define and adopt a common multimedia network protocol and application object model.

The first MOST based automobile, the BMW 7 Series, hit the streets in October of 2001. The Volvo XC90 SUV, Mercedes-Benz E Class, and Porsche Cayenne were soon to follow with their MOST based solutions. Additional platform models by Audi, BMW, DaimlerChrysler, Citroën, Peugeot, Saab and Volvo have also been introduced. The demand for MOST based automotive multimedia systems is driven by the growing trend of car manufacturers and suppliers to offer additional electronic and multimedia devices in all types of vehicles and the need to provide a complete and easy-to-use solution to the consumer. MOST continues to gain in popularity as more car makers and suppliers join this multimedia networking revolution

The MOST Cooperation has since expanded into a worldwide organization. Currently the MOST Cooperation consists of 16 automotive OEMs and over 60 suppliers (as of March 2006).

MOST is an excellent technology backed by an excellent team…

Prior to its March 2005 acquisition by SMSC, the Automotive Infotainment Systems product line was known as OASIS SiliconSystems, one of the largest privately held fabless semiconductor companies in Europe and specializing in automotive infotainment networking technology. Now SMSC's Automotive Infotainment Systems employs more than 190 people worldwide. Design and development centers have been established in Karlsruhe, Germany; Austin, Texas; and Göteborg, Sweden. Technical Marketing, Regional Sales, Worldwide Operations, and Administrative Services staffs are located in both the Karlsruhe and Austin offices. Technical Support teams are located in Karlsruhe, Germany; Austin, USA; Tokyo, Japan; Seoul, Korea.
