This processor provides very high performance in automotive and other embedded environments. This device has been designed with automotive and telematics applications in mind. What is new about the MPC5200? Generally, automotive class processors have not run at the clock speeds seen in the MPC5200. The external bus speeds of this device are up to 132 MHz and the internal execution speed for the CPU is up to 400 MHz. This provides the horsepower to do voice recognition, graphics processing and wireless communications. The MPC5200 is not just for automotive applications. In fact, this device will handle a tremendous range of applications.

Storage Organization and Management in TENEX I. Introduction
Storage Organization and Management in TENEX http://www.linique.com/dlm/tenex/fjcc72/ Storage Organization and Management in TENEX by Daniel L. Murphy Presented at the Fall Joint Computer Conference, 1972. Originally published in AFIPS Conference Proceedings Volume 41. I. Introduction In early 1969, BBN began an effort aimed at developing a new time-shared operating system. It was felt at the time that none of the commercially available systems could meet the needs of the research planned and in progress at BBN. The foremost requirement of the desired operating system was that it support a directly addressed process memory in which large list-processing computations could be performed. The cost of core storage prohibited the acquisition of sufficient memory for even one such process, and the problems of swapping such very large processes in a time-sharing environment made that solution technically infeasible as well. Paging was therefore the logical alternative, and our study and experience with list processing systems(1,2) led us to believe that using a demand-paged virtual memory system for such computations was a feasible approach. With demand paged process virtual memory added to our requirements, we found no existing system which could adequately meet our needs. Our approach was to take an existing system which was otherwise appropriate and add the necesary hardware to support paging. The system chosen was the DEC PDP-10 (3), which, although not paged, was available with a time-shared operating system and substantial support software. Consideration was given to modifying the existing PDP-10 operating system to support demand paging, but that approach was rejected because of the substantial amount of work which would be required, because of the inherent constraints imbedded in the architecture of any large system, and because development of a new operating system would allow the inclusion of a great many other features and facilities which were judged desirable. -

NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnn A Universal Host Table Network Working Group Mark Crispin Request for Comments 752 SU-AI NIC nnnnn 2 January 1979 A Universal Host Table ABSTRACT: The network host table in use at MIT and Stanford is described. This host table is superior to the NIC and Tenex host tables in several ways. A binary file, compiled from this host table, is also described. This file is used by subsystems on MIT's ITS and Stanford's WAITS timesharing systems for efficiency in host and network lookups. HISTORY: As with many other sites on the Arpanet, we found the NIC's host table unsuited to our needs. Part of the problem was because the NIC host table was often inaccurate and all too often failed to include several nicknames in common usage in our communities. In addition, the NIC host table's format was awkward for user programs to use, especially those which wanted to have the host table mapped into memory in some sort of structured binary form for efficient lookups. Finally, the NIC host table neglects to include some essential information. The ITS host table was originally designed to be compiled along with a network handling program (MIDAS, the PDP-10 assembler used, has a pseudo-op to insert a file into an assembly). In order to make the host table palatable to the assembler, every comment line began with a semicolon, and every actual data line began with the word HOST. Each program which used the host table defined HOST as an assembly macro before inserting the host table into the assembly. -

Lisp: Program Is Data
LISP: PROGRAM IS DATA A HISTORICAL PERSPECTIVE ON MACLISP Jon L White Laboratory for Computer Science, M.I.T.* ABSTRACT For over 10 years, MACLISP has supported a variety of projects at M.I.T.'s Artificial Intelligence Laboratory, and the Laboratory for Computer Science (formerly Project MAC). During this time, there has been a continuing development of the MACLISP system, spurred in great measure by the needs of MACSYMAdevelopment. Herein are reported, in amosiac, historical style, the major features of the system. For each feature discussed, an attempt will be made to mention the year of initial development, andthe names of persons or projectsprimarily responsible for requiring, needing, or suggestingsuch features. INTRODUCTION In 1964,Greenblatt and others participated in thecheck-out phase of DigitalEquipment Corporation's new computer, the PDP-6. This machine had a number of innovative features that were thought to be ideal for the development of a list processing system, and thus it was very appropriate that thefirst working program actually run on thePDP-6 was anancestor of thecurrent MACLISP. This earlyLISP was patterned after the existing PDP-1 LISP (see reference l), and was produced by using the text editor and a mini-assembler on the PDP-1. That first PDP-6 finally found its way into M.I.T.'s ProjectMAC for use by theArtificial lntelligence group (the A.1. grouplater became the M.I.T. Artificial Intelligence Laboratory, and Project MAC became the Laboratory for Computer Science). By 1968, the PDP-6 wasrunning the Incompatible Time-sharing system, and was soon supplanted by the PDP-IO.Today, the KL-I 0, anadvanced version of thePDP-10, supports a variety of time sharing systems, most of which are capable of running a MACLISP. -

The UNIX Time- Sharing System
1. Introduction There have been three versions of UNIX. The earliest version (circa 1969–70) ran on the Digital Equipment Cor- poration PDP-7 and -9 computers. The second version ran on the unprotected PDP-11/20 computer. This paper describes only the PDP-11/40 and /45 [l] system since it is The UNIX Time- more modern and many of the differences between it and older UNIX systems result from redesign of features found Sharing System to be deficient or lacking. Since PDP-11 UNIX became operational in February Dennis M. Ritchie and Ken Thompson 1971, about 40 installations have been put into service; they Bell Laboratories are generally smaller than the system described here. Most of them are engaged in applications such as the preparation and formatting of patent applications and other textual material, the collection and processing of trouble data from various switching machines within the Bell System, and recording and checking telephone service orders. Our own installation is used mainly for research in operating sys- tems, languages, computer networks, and other topics in computer science, and also for document preparation.
