  1. Processor-in-memory

    A Processor in memory PIM refers to a CPU computer processor CPU tightly coupled to computer memory memory , generally on the same Integrated circuit silicon chip . The chief goal of merging the processing and memory components in this way is to reduce memory latency and increase Bandwidth computing bandwidth . Alternatively reducing the distance that data needs to be moved reduces the power requirements of a system. Much of the complexity and hence power consumption in current processors stems from strategies to deal with avoiding memory stalls. Examples In the 1980s, a tiny CPU that executed FORTH was fabricated into a DRAM chip to improve PUSH and POP. FORTH is a Stack oriented programming language and this improved its efficiency. The Transputer also had large on chip memory given that it was made in the early 1980s making it essentially a Processor in memory. Notable PIM projects include the University of California, Berkeley http iram.cs.berkeley.edu IRAM project or the University of Notre Dame http www.nd.edu pim PIM effort.

  1. Perihelion Software

    Perihelion Software was a United Kingdom company founded in 1986 by Dr. Tim King along with a number of colleagues who had all worked together at MetaComCo on AmigaOS and written compilers for both the Amiga and the Atari ST . Perihelion Software produced an operating system for the INMOS Transputer called HeliOS . This was a system that looked like Unix but which could pass messages to processes running on either the same processor or another one. This was used in the Atari Transputer Workstation , among other places. Later HeliOS was ported to other processors including the ARM architecture . Perihelion Software also produced an in memory database system called Polyhedra DBMS Polyhedra the group responsible for this product was set up as a subsidiary Perihelion Technology Limited which did a management buyout in 1994. PTL later changed its name to Polyhedra plc in 1995, and then was acquired by a Sweden Swedish company called ENEA AB ENEA in 2001.

  1. KRoC

    KRoC , the Kent Retargetable occam Compiler , is an Occam programming language occam implementation that is based on the INMOS occam 2.1 compiler as a front end and a retargetable back end to produce machine code for various microprocessor s. Ports of the compiler have been made for PowerPC , SPARC , x86 and DEC Alpha Alpha processors. Along with the translation to different processors, the KRoC team have modified the compiler significantly, creating a compiler for what has become known as occam v2.5, and now as occam pi . Originally the translation from the occam compiler front end was by interpretation of the ASCII assembly language file. This worked reasonably well but was slow and occasionally inconvenient. The current KRoC compiler target is an Extended Transputer Code ETC , which is then translated into the target machine language. ETC code can be viewed as a kind of byte code it is a compact description of the compiler s intent on a Virtual Machine that is similar to the transputer . ETC code variants of the KRoC compiler exist for Intel x86 on Linux , x86 on Microsoft Windows Windows using Cygwin , and a SPARC port is in the works.

  1. Diakoptics

    Gabriel Kron s Diakoptics Greek dia &ndash through kopto &ndash cut,tear or Method of Tearing involves breaking a usually physical problem down into subproblems which can be solved independently before being joined back together to obtain a solution to the whole problem. Gabriel Kron was an unconventional Engineer who worked for GE in the US until his death in 1968. He was responsible for the first load flow electricity distribution system in New York. He was perhaps most famous for his Method of Tearing, a technique for splitting up physical problems into subproblems, solving each individual subproblem and then recombining to give an unexpectedly exact overall solution. The technique is efficient on sequential computers, but is particularly so on parallel architectures. Whether this holds for quantum parallelism is as yet unknown. It is peculiar as a decomposition method, in that it involves taking values on the intersection layer the boundary between subsystems into account. The method has been rediscovered by the parallel processing community recently under the name Domain Decomposition . A multilevel hierarchical version of the Method, in which the subsystems are recursively torn into subsubsystems etc., was published by Keith Bowden in 1991.

  1. INMOS G364 framebuffer

    Unreferenced date December 2009 The G364 framebuffer was a line of graphics adapter s using the SGS Thomson INMOS G364 chipset, produced by INMOS known for their transputer and eventually acquired by SGS Thomson and incorporated into STMicroelectronics in the early 1990s. The G364 included a RAMDAC and a 64 bit interface to Video RAM VRAM graphical memory to implement a framebuffer , but did not include any hardware based graphical acceleration other than a hardware cursor function. The G364 was largely similar in design and functionality to the G300 framebuffer , but had a 64 bit VRAM interface instead of the slower 32 bit interface of the lower price G300. The INMOS G364 is quite similar to the G332 found on the DECstation Personal DECstation 5000 Series Personal DECstation . Although the G364 was capable of providing comparatively high resolution output up to 1600× 1200 pixels at 8 bits per pixel, in many cases typically achieved only in Unix computer workstation workstations such as those of Sun Microsystems or Silicon Graphics SGI , it was not a popular chipset for the personal computer manufacturers of the early 1990s and was not adopted by any major workstation manufacturers. The G364 framebuffer found use in an after market Commodore Amiga graphics card, and as the primary graphics system sold with the MIPS Magnum MIPS Magnum 4000 series of MIPS architecture MIPS based Windows NT workstations.

  1. Minimal instruction set computer

    Minimal Instruction Set Computer MISC is a Microprocessor processor architecture with a very small number of basic operations and corresponding opcode s. Such instruction set s are commonly stack based rather than register based to reduce the size of operand specifiers. Such a stack machine architecture is inherently simpler since all instructions operate on the top most stack entries. A result of this is a smaller instruction set, a smaller and faster instruction decode unit, and overall faster operation of individual instructions. The downside is that instructions tend to have more sequential dependencies, reducing instruction level parallelism . MISC architectures have much in common with the Forth programming language and the Java Virtual Machine . Probably the most commercially successful MISC was the INMOS transputer .

  1. Process-oriented programming

    Programming paradigms Process oriented programming is a programming paradigm that separates the concerns of data structures and the concurrent processes that act upon them. The data structures in this case are typically persistent, complex, and large scale the subject of general purpose applications, as opposed to specialized processing of specialized data sets seen in high productivity applications HPC . The model allows the creation of large scale applications that partially share common data sets. Programs are functionally decomposed into parallel processes that create and act upon logically shared data. The paradigm was originally invented for parallel computers in the 1980s, especially computers built with transputer microprocessors by INMOS , or similar architectures. It evolved to meet deficiencies in the message passing paradigm of Occam programming language Occam and enable uniform efficiency when porting applications between distributed memory and shared memory parallel computers. The first example of the paradigm appears in the programming language Ease programming language Ease designed at Yale University ref name process cite paper last Ericsson Zenith authorlink Steven Ericsson Zenith title Programming with Ease Semiotic definition of the language publisher Yale University, Computer Science Technical Report YALEU DCS RR 809 date 1990 ref ref name process2 cite book last Ericsson Zenith authorlink Steven Ericsson Zenith title Process Interaction Models publisher Paris University date 1992 ref in 1990. Similar models have appeared since in the loose combination of SQL databases and objected oriented languages such as Java programming language Java , often referred to as object relational models and widely used in large scale distributed systems today. The paradigm is likely to appear on desktop computers as microprocessors increase the number of processors multicore per chip.

  1. Edinburgh Concurrent Supercomputer

    The Edinburgh Concurrent Supercomputer ECS was a large Meiko Computing Surface supercomputer . This transputer based, massively parallel system was installed at the University of Edinburgh during the late 1980s and early 1990s. History Following a pilot project involving an early 40 transputer Computing Surface installed in April 1986, funding was obtained from Science and Engineering Research Council SERC and the Department of Trade and Industry United Kingdom DTI for a much larger system using T800 transputers and a MicroVAX fileserver . The Edinburgh Concurrent Supercomputer Project ECSP was formed to manage and support the facility, which was commissioned at the end of 1987. Over the next few years, the system received several upgrades, including more transputers reaching, at its peak, around 400 processors and the installation of M VCS and MeikOS system software, which enabled multi user access and removed the need for the MicroVAX. In 1990, the Edinburgh Concurrent Supercomputer Project was succeeded by the Edinburgh Parallel Computing Centre , which consolidated the project with other parallel computing resources and activities within the University. The ECS continued to be used for a variety of academic and commercial research work. In October 1992 the ECS was reconfigured as a SPARC hosted Computing Surface with three SPARC host processors running SunOS and around 380 T800s. The system was finally decommissioned in August 1994.
