- The company was founded in 1981. Early versions of its processor technology were used first in data terminal systems and office computers, and then in document image processing systems and scanner controllers.
- In 1998 partnership was established with Array Printers AB, Sweden, to develop laser printer controllers. The use of Imsys technology significantly reduced the cost of Array’s printer controllers and greatly increased their functionality.
- In conjunction with a 1999 partnership with Ericsson Microelectronics (later Infineon Technologies), Imsys positioned its microprocessor IM1000 as an embedded Java platform for cellular communications.
- Early 2000, Imsys established, with its “Simple Network Application Platform”, SNAP, a niche in the market for embedded control, using Java and TCP/IP Ethernet connectivity.
- In October 2002, Imsys achieved the Sony Green Partner status adhering to the Sony Technical Standards for environment related substances for the IM1000 processor.
- In September 2005, Imsys received funding from a consortium headed by Creandum AB and Swedish Industrial Development Fund (Industrifonden).
- The IM3000 processor generation was introduced in the fall of 2007. These ICs have integrated peripheral functions, e.g. timers, Ethernet serial ports and analog interfaces, and their processor cores have 10 times higher efficiency and 5 times higher speed than the previous generation.
- In September 2009, a special application area, products for IEEE1588 Precise Timing Protocol, was spun out from Imsys to the new company Conemtech AB.
- At present, and for the future, Imsys is determined to utilize its architectural advantages for energy efficiency in the rapidly growing market of the Internet of Things, both in gateways and in intelligent nodes for sensors and actuators of all kinds. The company has close collaboration with the Royal Institute of Technology in Stockholm, Sweden, and with Wuxi Institute of Fudan University in Wuxi, China.
