Abstract :
A description is given of the port of SunOS, a derivative of the Unix operating system, to the scalable processor architecture (SPARC) RISC (reduced-instruction-set-computer) CPU. SPARC makes tradeoffs between hardware and software complexity. Operations implemented by microcode on CISC (complex-instruction-set computer) CPUs are supported by low-level operating system routines. The discussion covers virtual memory management, trap handling, and context switching.<>
