Oberon (operating System)
The Oberon System is a modular, single-user, single-process, multitasking operating system written in the programming language Oberon (programming language), Oberon. It was originally developed in the late 1980s at ETH Zurich. The Oberon System has an unconventional visual Text-based user interface#Oberon, text user interface (TUI) instead of a conventional command-line interface (CLI) or graphical user interface (GUI). This TUI was very innovative in its time and influenced the design of the Acme (text editor), Acme text editor for the Plan 9 from Bell Labs operating system and bears some similarities with the worksheet interface of the Macintosh Programmer's Workshop. The system also evolved into the multi-process, symmetric multiprocessing (SMP) capable A2 (operating system), A2 (formerly ''Active Object System'' (AOS), then ''Bluebottle''), with a zooming user interface (ZUI). History The Oberon operating system originated as part of the NS32000, NS32032-based Ceres (workst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niklaus Wirth
Niklaus Emil Wirth ( IPA: ) (15 February 1934 – 1 January 2024) was a Swiss computer scientist. He designed several programming languages, including Pascal, and pioneered several classic topics in software engineering. In 1984, he won the Turing Award, generally recognized as the highest distinction in computer science, "for developing a sequence of innovative computer languages". Early life and education Niklaus Emil Wirth was born in Winterthur, Switzerland, on 15 February 1934. He was the son of Hedwig (née Keller) and Walter Wirth, a high school teacher. Wirth studied electronic engineering at the Federal Institute of Technology, Zürich (ETH Zürich) from 1954 to 1958, graduating with a Bachelor of Science (B.S.) degree. In 1960, he earned a Master of Science (M.Sc.) from Université Laval in Quebec.

Acme (text Editor)
Acme is a text editor and graphical shell from the Plan 9 from Bell Labs operating system, designed and implemented by Rob Pike. It can use the Sam command language. The design of the interface was influenced by Oberon. It is different from other editing environments in that it acts as a 9P server. A distinctive element of the user interface is mouse chording. Overview Acme can be used as a mail and news reader, or as a frontend to wikifs. These applications are made possible by external components interacting with acme through its file system interface. Rob Pike has mentioned that the name "Acme" was suggested to him by Penn Jillette of Penn & Teller during a movie night at Times Square when he asked for a suitable name for a text editor that does "everything". Ports A port to the Inferno operating system is part of Inferno's default distribution. Inferno can run as an application on top of other operating systems, allowing Inferno's port of acme to be used on most op ...

Field-programmable Gate Array
A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be repeatedly programmed after manufacturing. FPGAs are a subset of logic devices referred to as programmable logic devices (PLDs). They consist of an array of programmable logic device, programmable logic block, logic blocks with a connecting grid, that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions. FPGAs are often used in limited (low) quantity production of custom-made products, and in research and development, where the higher cost of individual FPGAs is not as important, and where creating and manufacturing a custom circuit would not be feasible. Other applications for FPGAs include the telecommunications, automotive, aerospace, and industrial sectors, which benefit from their flexibility, high signal processing speed, and parallel processing abilities. A FPGA configuration is generally written using a hardware descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reduced Instruction Set Computer
In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions perform simpler operations. The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler to achieve given simpler instructions. The key operational concept of the RISC computer is that each instruction performs only one function (e.g. copy a value from memory to a register). The RISC computer usually has many (16 or 32) high-speed, general-purpose registers with a load–store architecture in which the code for the register-register instructions (for performin ...

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Zooming User Interface
In computing, a zooming user interface or zoomable user interface (ZUI, pronounced zoo-ee) is a type of graphical user interface (GUI) where users can change the scale of the viewed area in order to see more detail or less, and browse through different documents. Information elements appear directly on an infinite virtual desktop (usually created using vector graphics), instead of in windows. Users can pan across the virtual surface in two dimensions and zoom into objects of interest. For example, as you zoom into a text object it may be represented as a small dot, then a thumbnail of a page of text, then a full-sized page and finally a magnified view of the page. ZUIs use zooming as the main metaphor for browsing through hyperlinked or multivariate information. Objects present inside a zoomed page can in turn be zoomed themselves to reveal further detail, allowing for recursive nesting and an arbitrary level of zoom. When the level of detail present in the resized obje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
