Abstract
Today's high­performance RISC microprocessors have been
highly tuned for integer and floating point application per­
formance. These architectures have paid less attention to
operating system requirements. At the same time, new op­
erating system designs often have overlooked modern archi­
tectural trends which may unavoidably change the relative
cost of certain primitive operations. The result is that op­
erating system performance is well below application code
performance on contemporary RISCs.
This paper examines recent directions in computer ar­
chitecture and operating systems, and the implications of
