Whitesmiths C
Whitesmiths Ltd. was a software company founded in New York City by P. J. Plauger, Mark Krieger and Gabriel Pham, and last located in Westford, Massachusetts. It sold a Unix-like operating system called Idris (operating system), Idris, as well as the first commercial C (programming language), C compiler, Whitesmiths C. The Whitesmiths compiler, first written for the PDP-11, was released in 1978 and compiled a version of C similar to that accepted by Version 6 Unix (Dennis Ritchie's original C compiler). It was an entirely new implementation, borrowing no code from Unix. Today, it is mainly remembered for lending its name to a particular indent style#Whitesmiths style, indentation style, originally used in the code examples which accompanied it. Whitesmith's first customer for their C compiler was Fischer & Porter, a process control company then located in Warminster, Pennsylvania. Besides PDP-11, the compiler had code generators for Intel 8080/Zilog Z80, Motorola MC68000, and VAX-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warminster, Pennsylvania
Warminster Township (also referred to as Warminster) is located in Bucks County, Pennsylvania, United States. It was formally established in 1711. The township is 13.7 miles north of Philadelphia and had a population of 32,682 according to the 2010 U.S. census. History The town was called Warminster Township as early as 1685, before its borders were formally established in 1711. It was originally part of Southampton Township, which was founded in 1682 by William Penn. Warminster was named after a small town in the county of Wiltshire, at the western extremity of Salisbury Plain, England. Warminster, Pennsylvania was mostly settled by English and Scotch-Irish colonists after William Penn received a grant of land in the area from King Charles, II. It was the site of the Battle of Crooked Billet during the Revolutionary War, which resulted in a resounding defeat for George Washington's colonial troops. Warminster's Craven Hall is included in the National Register of Historic Place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mergers And Acquisitions
Mergers and acquisitions (M&A) are business transactions in which the ownership of companies, other business organizations, or their operating units are transferred to or consolidated with another company or business organization. As an aspect of strategic management, M&A can allow enterprises to grow or downsize, and change the nature of their business or competitive position. Technically, a is a legal consolidation of two business entities into one, whereas an occurs when one entity takes ownership of another entity's share capital, equity interests or assets. A deal may be euphemistically called a ''merger of equals'' if both CEOs agree that joining together is in the best interest of both of their companies. From a legal and financial point of view, both mergers and acquisitions generally result in the consolidation of assets and liabilities under one entity, and the distinction between the two is not always clear. In most countries, mergers and acquisitions must co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermetrics
AverStar (formerly Intermetrics, Inc.) was a software company founded in Cambridge, Massachusetts in 1969 by several veterans of M.I.T.'s Instrumentation Laboratory who had worked on the software for NASA's Apollo Program including the Apollo Guidance Computer. The company specialized in compiler technology. It was responsible for the design and implementation of the HAL/S programming language, used to write the Space Shuttle PASS (Primary Avionics Software System). It participated in the design effort leading to the Ada programming language, designed the Red language, one of the finalists in the design competition, and wrote one of the first production-quality Ada compilers. The large-scale Ada 95 revision of the language was designed at Intermetrics. Intermetrics merged with Whitesmiths Ltd. in December 1988. In 1997, Intermetrics merged with computer game developer Looking Glass Studiosbr> In 1998, Intermetrics acquired Pacer Infotec, and changed its name to 'AverStar'. A ...

ANSI C
ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22/WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Historically, the names referred specifically to the original and best-supported version of the standard (known as C89 or C90). Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers. History and outlook The first standard for C was published by ANSI. Although this document was subsequently adopted by ISO/IEC and subsequent revisions published by ISO/IEC have been adopted by ANSI, "ANSI C" is still used to refer to the standard. While some software developers use the term ISO C, others are standards-body neutral and use Standard C. Standardizing C In 1983, the American National Standards Institute formed a committee, ...

Motorola
Motorola, Inc. () was an American Multinational corporation, multinational telecommunications company based in Schaumburg, Illinois, United States. After having lost $4.3 billion from 2007 to 2009, the company split into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is the legal successor to Motorola, Inc., as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was acquired by Lenovo in 2014.

8-bit
In computer architecture, 8-bit Integer (computer science), integers or other Data (computing), data units are those that are 8 bits wide (1 octet (computing), octet). Also, 8-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on processor register, registers or Bus (computing), data buses of that size. Memory addresses (and thus address buses) for 8-bit CPUs are generally larger than 8-bit, usually 16-bit. 8-bit microcomputers are microcomputers that use 8-bit microprocessors. The term '8-bit' is also applied to the character sets that could be used on computers with 8-bit bytes, the best known being various forms of extended ASCII, including the ISO/IEC 8859 series of national character sets especially ISO/IEC 8859-1, Latin 1 for English and Western European languages. The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory ...

16-bit
16-bit microcomputers are microcomputers that use 16-bit microprocessors. A 16-bit register can store 216 different values. The range of integer values that can be stored in 16 bits depends on the integer representation used. With the two most common representations, the range is 0 through 65,535 (216 − 1) for representation as an (unsigned) binary number, and −32,768 (−1 × 215) through 32,767 (215 − 1) for representation as two's complement. Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory. If a system uses segmentation with 16-bit segment offsets, more can be accessed. 16-bit architecture The MIT Whirlwind ( 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversi ...

Cross Compiler
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on an Android smartphone is a cross compiler. A cross compiler is useful to compile code for multiple platforms from one development host. Direct compilation on the target platform might be infeasible, for example on embedded systems with limited computing resources. Cross compilers are distinct from source-to-source compilers. A cross compiler is for cross-platform software generation of machine code, while a source-to-source compiler translates from one coding language to another in text code. Both are programming tools. Use The fundamental use of a cross compiler is to separate the build environment from target environment. This is useful in several situations: * Embedded computers where a device has highly limited resources. For example, a microwave oven will have a ...

Indent Style
In computer programming, an indentation style is a convention governing the indentation of blocks of code to convey program structure. This article largely addresses the free-form languages, such as C and its descendants, but can be (and often is) applied to most other programming languages (especially those in the curly bracket family), where whitespace is otherwise insignificant. Indentation style is only one aspect of programming style. Indentation is not a requirement of most programming languages, where it is used as secondary notation. Rather, indenting helps better convey the structure of a program to human readers. Especially, it is used to clarify the link between control flow constructs such as conditions or loops, and code contained within and outside of them. However, some languages (such as Python and occam) use indentation to determine the structure instead of using braces or keywords; this is termed the off-side rule. In such languages, indentation is meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
