Realtime UNIX "UNOS" and Its Application

Kazuyuki Sakurada, Satoshi Kuroiwa, Kensuke Iwaki, Osamu Sekigawa
Synopsis :
Kawasaki Steel launched the Universe super-microcomputer family of systems to the Japanese market in October 1988. The Universe systems run under the operating system, UNOS, which is compatible with AT&T UNIX System V. The UNOS is an entirely independent operating system developed to provide capabilities beyond the limited real-time and file system capabilities of standard UNIX. Such extensions are essential in commercially based applications which require prompt response and high reliability. Since its introduction to Japan, the UNOS operating system has been meeting a large number of real-time application needs. Typical application of UNOS is online transaction processing in which database resides and exchanges its data frequently through multiple I/O ports.
