Imsys' patented technology for reconfigurable microprocessor cores enables cost effective integration of connectivity to machines or entire plants, as well as to field devices located outside the main facilities, providing remote control, monitoring and optimization of such assets. The processors are programmed in C/C++, assembler or Java. For efficient Java execution the full Java byte codes are part of a special instruction set. The platform is well suited for advanced Java ME systems with many threads. & ?2 B7 w+ `: X6 G 2 G9 p) K7 \9 a/ `4 VImsys' proprietary microcontroller integrated circuits and basic software together constitutes a low-cost solution that is easy to implement in target products; no knowledge of processor or operation system is needed. OEMs essentially need to connect Imsys controllers to the hardware it is to control, and add Java software, which is developed and tested on any computer, using standard tools. / o) L/ G7 E+ S+ P

In 1998 Imsys established partnership 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. 0 K/ o# s& `, c( DIn conjunction with a 1999 partnership with Ericsson Microelectronics (later Infineon Technologies), Imsys positioned its "System On A Chip", the IM1000 as an embedded Java platform for cellular communications. 9 Z" A. s8 O# a3 E* I
