NEW BOOK ANNOUNCEMENT REAL-TIME UNIX SYSTEMS Design and Application Guide by Borko Furht, Dan Grostick, David Gluch, Guy Rabbat, John Parker, Meg McRoberts Modular Computer Systems, Inc. This book is a design and application guide to real-time UNIX systems; it describes general computer requirements for time-critical applications, and related requirements for real-time operating systems. "Real-Time UNIX Systems" presents various approaches to designing real-time UNIX operating systems. The REAL/IX operating system, a fully preemptive real-time UNIX operating system, is described in detail. Guidelines for designing real-time applications using the REAL/IX system are presented, including a number of fully-tested real-time program examples. Special emphasis is given to the description of the critical features of the REAL/IX system, including a fully-preemptive kernel, a fixed priority scheduler, and a memory management scheme which includes memory preallocation. Fast interprocess communications mechanisms, common event notification and binary semaphores are also discussed, and examples of how to effectively use these in real-time applications are given. This book also describes a fast file subsystem, which supports preallocation of space and contiguous files and provides the capability of bypassing the buffer cache for fast file I/O. Enhancements to the UNIX I/O subsystem, required for real-time applications, are presented. "Real-Time UNIX Systems" describes in detail two case studies of designing real-time systems. Real-time systems designers, UNIX programmers and operating systems designers will find this book to be an invaluable reference. It is also suitable for a course on the subject.
