SOFTWARE 

S.2 DSRT (dynamic soft real-time) system: Public release as part of my PhD thesis research. 

The dynamic soft real time scheduler (DSRT) 2.0 is a user-level dynamic scheduler that can 

schedule soft real time (RT) periodic and aperiodic tasks. It is used for running multimedia 

applications such as video/audio processing, animation are time-sensitive that need 

minimal jitter to accomplish a good viewing quality. The DSRT system is a 

middleware-level scheduler that can be used by copying executable scheduler into the 

target machine without modifying underlying kernel. 

IMPACT: 

。 The DSRT system incorporated into the Globus project (a GRID computing) 

。 The CPU Service Classes concept re-implemented in Windows Vista Multimedia 

Class Scheduler. 

。 The iDSRT system is open source license software. 

S.1 ROAM system: Produced at NTT DoCoMo USA research lab. It is a multi-platform 

application development framework for heterogeneous mobile devices. It enables a 

developer to develop cross-device mobile applications that can runtime migrate across 

different heterogeneous devices.
