Imsys 科技公司主要开发嵌入式应用处理器、模块和开发工具，今天发布一套支持IEEE 1588精确时钟协议的开发平台

* V( |, }; Q, k* s6 |) e从电路连接到以包为基础的系统的转变产生了对设备同步的需求。IEEE 1588 2002是 LXI Consortium，以太网Powerlink和以太网/IP工业标准的一部分。今年晚些时候发布的协议第二版包括了许多加强内容，并提供亚微秒级精确度从而满足通讯工业在基站和femtocell 方面的需求。该1588开发套件是一套易用工具，包括一个可以通过程序设计来调整时间和频率的API。其周期性输出PPS，可以获得用户所定义的频率，如10或30.72MHz。开发者可以选择ASM32, C或JAVA中任意一种编程语言或使用混合编程。Imsys正在和苏黎世应用科学大学合作实现协议堆栈。

Business
Imsys Technologies AB designs and supplies networked microprocessor solutions to OEMs in the market of Embedded Control and Telematic systems.
: t! w- D7 R9 V, j6 s
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.

% m, ^( k( A( F& X% [1 GImsys' 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.

' E+ [1 f* [" }' g1 [9 E, q5 G# WIn 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.
In 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.

Imsys是一家瑞典公司，主要产品是java芯片，也就是芯片内建java虚拟机

芯片最大的优点就是功耗低，性能优，支持多款语言，并可以根据客户需求做优化
