Suneel Kumar Khurmi, B.Sc.(Eng), A.C.G.I
THE MICROPROCESSOR AND COMPUTER-AIDED DESIGN AND MANUFACTURE by Suneel Kumar Khurmi, B.Sc.(Eng), A.C.G.I. September 1982 A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Membership of the Imperial College. Department of Mechanical Engineering Imperial College of Science and Technology University of London - 2 - ABSTRACT The thesis describes the design, implementation and application of software for a low cost microcomputer based Computer-Aided Design and Computer-Aided Manufacture (CAD/CAM) system. The CAD workstation consists of a Motorola 68B09 8-bit microcomputer, a floppy disc, a Hewlett-Packard graphics ^ VDU, a printer and a plotter. The Numerical Control system consists of a hierarchical multi-microcomputer control system on a retrofitted Student Colchester lathe and a Bridgeport milling machine. t The CAD and NC part-programming software consists of several packages which assist the operator through the conceptual realms of product design and manufacture. They assist in the storage of the geometrical and technological information associated with the product, geometrical t editing, draughting, design analysis, cutter path derivation, NC simulation and part program generation. These packages are executed sequentially to produce 2/2^ dimensional NC part programs for a variety of machine tools, for example the Colchester and Bridgeport machines. Most of the packages are modular and have been developed in * , the high level language Pascal to maintain system modularity, flexibility and expandability. - 3 - ABSTRACT The thesis is subdivided into four main sections. The first section introduces the reader to microprocessors, CAD, CAM and the implications associated with CAD/CAM integration.

From: [email protected] (J. Bayko) Date: 12 Jun 92 18:49:18 GMT Newsgroups: alt.folklore.computers,comp.arch Subject: Great Microprocessors of the Past and Present I had planned to submit an updated version of the Great Microprocessor list after I’d completed adding new processors, checked out little bits, and so on... That was going to take a while... But then I got to thinking of all the people stuck with the origional error-riddled version. All these poor people who’d kept it, or perhaps placed in in an FTP site, or even - using it for reference??! In good conscience, I decided I can’t leave that erratic old version lying out there, where people might think it’s accurate. So here is an interim release. There will be more to it later - the 320xx will be included eventually, for example. But at least this has been debugged greatly. Enjoy... John Bayko. — Great Microprocessors of the Past and Present (V 3.2.1) Section One: Before the Great Dark Cloud. ————————— Part I: The Intel 4004 (1972) The ﬁrst single chip CPU was the Intel 4004, a 4-bit processor meant for a calculator. It processed data in 4 bits, but its instructions were 8 bits long. Internally, it featured four 12 bit(?) registers which acted as an internal evaluation stack. The Stack Pointer pointed to one of these registers, not a memory location (only CALL and RET instructions operated on the Stack Pointer). There were also sixteen 4-bit (or eight 8-bit) general purpose registers The 4004 had 46 instructions.

AccessionIndex: TCD-SCSS-T.20121208.043 Accession Date: 8-Dec-2012 Accession By: Dr.Brian Coghlan Object name: Western Digital WD90 Pascal Microengine Vintage: c.1979 Synopsis: Commercial microcoded high-level language machine to execute Pascal p- code, based on WD9000 chipset developed for LSI-11 (see VAX 11/780 Console Processor elsewhere in collection). S/N: 668. Description: This unusual commercial microcoded high-level language machine was designed to execute Pascal p-code. It was based on same WD9000 chipset that was developed c.1978 by Western Digital for the DEC LSI-11 (see VAX 11/780 Console Processor elsewhere in collection). The WD90 was introduced by Western Digital in 1979. WD-9000 five chip microprocessor chip set was based on the MCP-1600 chipset for the LSI-11, with a four-phase 3MHz clock. Early CPU boards had poor power and ground layouts, leading to a justified reputation for unreliability. The CPU chipset included a 16-bit Datapath Chip containing the microcode decoder, ALU and register file, a Control Chip containing the portions of the control processor and I/O logic and the microinstruction counter, and 4kB of microcode ROM in three MICROM Chips, each 512 x 22-bits. The five chips are interconnected to an 18-bit microinstruction bus. The p-code interpreter was implemented in the microcode ROM, so the p-code was, effectively, its native (virtual) machine language, referred to variously as the pseudo-machine or p-machine. The WD90 was the first commercial microprocessor to include floating-point instructions without a separate FPU. Typically the WD90 was sold with 64kB of RAM (32k x 16-bits, in 32 x 16kbit DRAMs), but could accommodate 128kB by piggybacking extra DRAM and modifying the PCB layout.

UCSD Pascal - Wikipedia, the Free Encyclopedia
UCSD Pascal - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/UCSD_Pascal UCSD Pascal From Wikipedia, the free encyclopedia UCSD Pascal was a popular implementation of the programming language Pascal. Notable extensions to standard Pascal include separately compilable Units and a String type. Both of these extensions influenced the design of the Ada programming language. Some intrinsics were provided to accelerate string processing (e.g. scanning in an array for a particular search pattern); other language extensions were provided to allow the UCSD p-System to be self-compiling and self-hosted. UCSD Pascal was based on a p-code machine architecture. Its contribution to these early virtual machines was to extend p-code away from its roots as a compiler intermediate language into a full execution environment. The UCSD Pascal p-Machine was optimized for 16-bit microcomputers with only 64KB of memory. James Gosling cites UCSD Pascal as a key influence (along with the Smalltalk virtual machine) on the design of the Java virtual machine. The UCSD Pascal compiler was distributed as part of a portable operating system, the p-System. There were four versions of UCSD p-code engine (p-code incompatible) each with several revisions of the p-System (and UCSD Pascal); represented with the leading Roman Numeral; operating system revisions were enumerated as the "dot" number following the p-Code Roman Numeral. vis: II.3 represented the third revision of the p-System running on the second revision of the p-Machine. Version I Original version, never officially distributed outside of the University of California, San Diego.

The Varied Careers of Kenneth L. Bowles RETROSPECTIVE
RETROSPECTIVE The varied careers of Kenneth L. Bowles RETROSPECTIVE M. Granger Morgana,1, Mark Overgaardb,2, and Ann E. Bowlesc It is not unusual for the careers of scientists and engineers to span a range of topics, driven by their insatiable curiosity about how things work, the fun they derive from problem solving, an aesthetic sense for “sweet solu- tions,” and a joy in sharing their knowledge with others. Few careers have spanned as wide a breadth, or better reflected the technological explosion in the second half of the 20th century, than that of Kenneth L. Bowles, who died in California on August 15, 2018. Bowles (“Ken” to everyone who knew him) began Fig. 1. The large array of the Jicamarca Radar (Left).
