There are usually(but not always) two types of licenses involved with a Real Time OS - a Run Time license and a Host Development License. The Host Development License allows for the development of the software(C/C++/Java) on a Host machine. To execute the developed software on the Target Platform(which may be different form the development host), a Run Time license is usually required per Target CPU. Hope this helps Ray

Cliff: Ray's response is fine, but I thought I would answer you as well. A run time license is essentially a royalty that WIND receives for each product that uses its VxWorks, IxWorks, or other variation real time operating system (RTOS). As part of the Tornado software, which includes an entire tool suite of compilers, debuggers, simulators, etc.; Tornado buyers also negotiate for the right to use WIND's RTOS (VxWorks or IxWorks) on each one of their developed products. The often discussed Intel deal on the I960 chip is one, but their are literlally thousands more, ranging from military applications to switches and other types of telecom equipment. WIND provides this run time license, which is the right to port the operating system onto the end product. The royalty typically scales down depending upon the number of applications. eg. $100,000 for one application (like the Mars Pathfinder), to $1.50 for each I960 chip that Intel makes. Hope this helps. Regards, Jason Cogan
