Motivation for RT-EPA

• Emerging Soft Real-Time Applications
  • Virtual Reality, Multimedia, Flexible Automation and Control

• Device Interfaces with RT Processing Between Them
  • Range of Device Bandwidths and Characteristics
    Aperiodic Bursty Periodic
  • Range of RT Performance Reliability Required
    Best-Effort Confidence-Based Guaranteed

• Negotiated Service & Control of Kernel Processing Pipelines
  • Kernel Pipeline Efficiency Well-Demonstrated (Fall & Govindan)
  • Use Real-Time Kernel Threads and Provide Trades between Utilization and Expected Number of Deadline Misses
