University of Kansas Current Interests Networked Embedded Systems Large Real Time Systems –Heterogeneous “Parallel” Nodes –Node Architectures –Computing Paradigms Computer Architecture Data Intensive Architectures –Scalar, Parallel CPU Cores, Caches –Asynchronous Systems, Optical Systems Future Paradigms

University of Kansas Networked Embedded Systems Autonomous “networked” Embedded Systems –Embedded Systems Much More Than Closed Loop Periodic Systems –Dynamic Operation of Real Time Networks Network Key To New Embedded Systems Data Sharing/Service Co-ordination –System Resource Management Dynamic Workloads Fault Detection/Location Things break –Models For Data Acquisition and Transfer –Very Dynamic Data Transmission Requirements –Variable Communications Bandwidth Requirements –Buffering

University of Kansas Example Autonomous System

University of Kansas Computer Architecture General Movement to Systems On A Chip Integration of Analog/Digital Data Intensive Architectures –Processor In Memory Approach –D-Base, Multimedia Applications –Low Level Communications Future Paradigms –Instruction Set Architecture (ISA) Definition –“old” ISA is well… Old…. Von Neumann Load/Store –Asynchronous Paradigm Is Also Interesting
