whenever a real time task is ready to run it preempts windows handles all real time activities and then resumes windows the lowest priority irmx task after all real time activities have completed . intime rtos for windows edit like irmx for windows the intime rtos also installs on a standard windows system . once installed the intime rtos schedules all real time processes to run first at a higher priority than windows . the intime rtos runs as a separate independent kernel outside of the windows kernel without modifying the windows kernel drivers or applications . real time processes run on the intime kernel and non real time processes run on windows . windows application threads communicate with their real time counterparts on the intime kernel through a special api that facilitates coordination and data sharing . evm virtualization platform for windows edit the evm virtualization platform provides a virtual machine that hosts real time and embedded operating systems running alongside microsoft windows . the evm platform requires intel virtualization technology or intel vt in order to operate . the guest os that runs within the vmm runs in parallel with windows on an industry standard pc compatible multi core platform . legacy i o can be emulated using intel vt. virtual communication channels such as a virtual ethernet or a virtual serial link provide a means for embedded applications running on the vmm to coordinate with windows applications . direct hardware access to i o and deterministic timing interrupt latency needs are addressed by giving the guest os direct access to time critical hardware . i o is assigned exclusively to each guest os so existing native device drivers have direct access to real hardware . development environment edit tenasys rtos tools are integrated into the microsoft visual studio ide . notes edit radisys to acquire multibus business from intel corp. intel to take 17 % equity stake in radisys 1 who owns multibus or older intel product radisys ships intime to customers worldwide edn 8th annual innovation awards 1997 winners and finalists real time elements donald j. ewing professor emeritus electrical engineering and computer science university of toledo eecs 4170 5170 7170 class notes 2 references edit schwaderer curt may 2006 . real time os for multicore processors serious implications for advancedtca systems pdf . compactpci & advancedtca systems . history and technology overview neumann dean ;
