Rmox: a Raw-Metal Occam Experiment
Communicating Process Architectures – 2003 269 Jan F. Broenink and Gerald H. Hilderink (Eds.) IOS Press, 2003 RMoX: A Raw-Metal occam Experiment Fred BARNES†, Christian JACOBSEN† and Brian VINTER‡ † Computing Laboratory, University of Kent, Canterbury, Kent, CT2 7NF, England. {frmb2,clj3}@kent.ac.uk ‡ Department of Mathematics and Computer Science, University of Southern Denmark, Odense, Denmark. [email protected] Abstract. Operating-systems are the core software component of many modern com- puter systems, ranging from small specialised embedded systems through to large distributed operating-systems. This paper presents RMoX: a highly concurrent CSP- based operating-system written in occam. The motivation for this stems from the overwhelming need for reliable, secure and scalable operating-systems. The major- ity of operating-systems are written in C, a language that easily offers the level of flexibility required (for example, interfacing with assembly routines). C compilers, however, provide little or no mechanism to guard against race-hazard and aliasing er- rors, that can lead to catastrophic run-time failure (as well as to more subtle errors, such as security loop-holes). The RMoX operating-system presents a novel approach to operating-system design (although this is not the first CSP-based operating-system). Concurrency is utilised at all levels, resulting in a system design that is well defined, easily understood and scalable. The implementation, using the KRoC extended oc- cam, provides guarantees of freedom from race-hazard and aliasing errors, and makes extensive use of the recently added support for dynamic process creation and channel mobility. Whilst targeted at mainstream computing, the ideas and methods presented are equally applicable for small-scale embedded systems — where advantage can be made of the lightweight nature of RMoX (providing fast interrupt responses, for ex- ample). -

Oral History Interview with John Brackett and Doug Ross
An Interview with JOHN BRACKETT AND DOUG ROSS OH 392 Conducted by Mike Mahoney on 7 May 2004 Needham, Massachusetts Charles Babbage Institute Center for the History of Information Processing University of Minnesota, Minneapolis Copyright, Charles Babbage Institute John Brackett and Doug Ross Interview 7 May 2004 Oral History 392 Abstract Doug Ross and John Brackett focus on the background of SofTech and then its entry into the microcomputer software marketplace. They describe their original contact with the University of California at San Diego (UCSD) and licensing the p-System which had been developed there. They discuss the effort required to bring the program to production status and the difficulties in marketing it to the sets of customers. They talk about the transition from 8 bit to 16 bit machines and how that affected their market opportunities. They conclude with a review of the negotiations with IBM and their failure to get p-System to become a primary operating environment. That, and the high performance of Lotus 1-2-3, brought about the demise of the p- System. [John Brackett requested that the following information from Wikipedia, the free encyclopedia, be provided as an introduction to this oral history interview: “UCSD p-System or UCSD Pascal System was a portable, highly machine independent operating system based upon UCSD Pascal. The University of California, San Diego Institute for Information Systems developed it in 1978 to provide students with a common operating system that could run on any of the then available microcomputers as well as campus DEC PDP-11 minicomputers. UCSD p- System was one of three operating systems (along with PC-DOS and CP/M-86) that IBM offered for its original IBM PC. -

A Port of the MINIX OS to the Powerpc Platform

Alting Weth. W. de Boerstraat 18 1788AT Den Helder, the Netherlands email: [email protected] Abstract The main goal of this project is to indicate what it means to port an operating system from one architecture to another, and provide a programming paradigm that would make future ports easy and fast. The “natively” supported architecture of MINIX is the IBM PC compatible, that's built around the Intel architecture. This is a CISC architecture with hardware support for easy stack usage. The choice for the POWER architecture could not have been further away as this is a RISC architecture, and completely” different in many ways. This thesis will focuses on the model created for creating portable system code. Not to be confused with portable programs using a “standard” API. It will describe the changes made and problems faced porting the MINIX code base. The places where changes are made can be viewed as hotspots. For every new architecture compatibility problems are to be expected there. Some hotspots are used as example and the solution taken for MinixPPC is presented to the reader. -

The UCSD P-System STATUT ORIL Y EX E:M PT
DOCfi!D(ov~ by NSA on 12-01-2011, Transparency Case# 5335]UNCLASSIFIED The UCSD p-System STATUT ORIL Y EX E:M PT This paper discusses the UCSD p-System, an operating system for small computers developed at the University of California at San Diego. The discussion includes the overall system, file managing, editing, and programming in Pascal on the system. INTRODUCTION The UCSD p-System was developed at the University of California at San Diego to support Pascal programming on microcomputers. Similar to MS-DOS, the p-System is an operating system for small computers but is, in many ways, very different. The p-System is written in Pascal and now supports not only Pascal, but also FORTRAN, COBOL, BASIC, and Modula-2. The concept was to have an operating system that, once it was implemented on a machine, allowed any program written under that operating system to be truly transportable from computer to computer. That is to say, the p-System compiler would not actually translate the program into a language that was specific for, say, an 8088 chip on the IBM-PC, but rather would translate it into a "pseudo" language that, when used with an operating system designed for the PC, would run correctly. Similarly, if the operating system were implemented on a Digital Equipment Corporation (DEC) computer, this same pseudo code would still work properly with no modifications. The particular version of UCSD p-System tested was written for the IBM-PC and requires two single-sided double-density disk drives and at least 128K of memory.
