| Research Abstract |
We have studied the data-driven development environment to enhance reusability provided by real-time execution systems to build multi-media networking environment. At the same time, we have researched super-integrated data-driven processor architecture suitable for the multi-media networking environment. Following results have been obtained by the studies.
(Data-Driven Development E nvironment)
We have realized the first version prototype of reuse-oriented data-driven development environment that can directly generate programs from their specifications. The environment also supports side-effects detection based on symbolic execution. Through actual software development such as TCP/IP (Transmission Control Protocol/Internet Protocol), the prototype has demonstrated its effectiveness for both side-effects detection and so-called verification. Furthermore, in order to make a program satisfy its performance requirements essentially needed in real-time processing, we studied an optimization m

ethod of program allocation to multi-processors. In this method, users can interactively optimize the initial assignment generated by genetic algorithm. An experimental evaluation has shown that the method is effective both to improve throughput and to reduce turn-around time of program.
(Networking Oriented Data-Driven Processor Architecture)
As a data-driven implementation of multi-media networking environment, we have realized TCP/IP, GIOP/IIOP (General inter-ORB Protocol/Internet Inter-ORB Protocol) and video/audio compression on super-integrated data-driven processors. We have demonstrated that effective multi-processing without any overhead is possible. Furthermore, we showed that TCP / IP over ATM (Asynchronous Transfer Mode) can be realized by super-integrated data-driven processor prototype. In this processor, off-chip communication penalty is minimized by super-integration. And this processor has enhanced instructions tuned for TCP/IP handling. From the studies, networking oriented data-driven processor architecture has become clear. Also it is shown that the protocol handlers and multi-media applications can be implemented on a single chip multi data-driven processor. Less
