Abstract
Microprocessor architects, supported by advances in VLSI technology, have been enormously successful at steadily accelerating the performance of application software. However, operating system performance has lagged due to a divergence between operating system and architectural trends. Unfortunately, some recent work in this area has targeted average-case performance improvements with little or no consideration for the worst-case behavior that must be considered for real-time applications. This paper explores whether one can improve the worst-case performance of operating systems, and as a result, the schedulability of real-time task-sets, using specific hardwareassisted operating system primitives without sacrificing flexibility. The Intel 80960XA Microprocessor, which directly supports basic operating system primitives in hardware, provides an excellent platform to explore operating system hardware and software boundary issues. This paper specifically analyzes the viability of an har...
