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

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
