Programmable Logic Devices
A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. Unlike digital logic constructed using discrete logic gates with fixed functions, a PLD has an undefined function at the time of manufacture. Before the PLD can be used in a circuit it must be programmed to implement the desired function. Compared to fixed logic devices, programmable logic devices simplify the design of complex logic and may offer superior performance. Unlike for microprocessors, programming a PLD changes the connections made between the gates in the device. PLDs can broadly be categorised into, in increasing order of complexity, Simple Programmable Logic Devices (SPLDs), comprising programmable array logic, programmable logic array and generic array logic; Complex Programmable Logic Devices (CPLDs) and Field-Programmable Gate Arrays (FPGAs). History In 1969, Motorola offered the XC157, a mask-programmed gate array with 12 gates and 30 uncommitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Vantis
Vantis plc was an accountancy firm based in London, England, providing accounting, tax and business advice to owner-managed businesses, listed companies, not for profit organisations, high-net-worth individuals and other professionals. It was placed in administration on 29 June 2010 and promptly broken up, with the various offices and businesses being sold as going concerns. History Vantis was formed as a "consolidator", inviting existing small local accountancy partnerships to join it and become part of a national company. It was listed on the Alternative Investment Market (AIM) in May 2002. In 2005 it took over struggling competitor Numerica, selling some of the offices to BDO Stoy Hayward. Numerica was one of the first consolidators, led by former firm Levy Gee; at a time when audit work was restricted to partnerships, it was the first publicly listed company to employ staff part-time who also did audit work for an associated partnership. Numerica had been the UK member of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second Source
In the electronics industry, a second source is a company that is licensed to manufacture and sell components originally designed by another company (the first source). It is common for engineers and purchasers to avoid components that are only available from a single source, to avoid the risk that a problem with the supplier would prevent a popular and profitable product from being manufactured. For simple components such as resistors and transistors, this is not usually an issue, but for complex integrated circuits, vendors often react by licensing one or more other companies to manufacture and sell the same parts as second sources. While the details of such licenses are usually confidential, they often involve cross-licensing, so that each company also obtains the right to manufacture and sell parts designed by the other. Examples MOS Technology licensed Rockwell and Synertek to second-source the 6502 microprocessor and its support components. Intel licensed AMD to second-s ...

Canonical Normal Form
In Boolean algebra, any Boolean function can be expressed in the canonical disjunctive normal form ( CDNF) or minterm canonical form and its dual canonical conjunctive normal form ( CCNF) or maxterm canonical form. Other canonical forms include the complete sum of prime implicants or Blake canonical form (and its dual), and the algebraic normal form (also called Zhegalkin or Reed–Muller). ''Minterms'' are called products because they are the logical AND of a set of variables, and ''maxterms'' are called sums because they are the logical OR of a set of variables. These concepts are dual because of their complementary-symmetry relationship as expressed by De Morgan's laws. Two dual canonical forms of ''any'' Boolean function are a "sum of minterms" and a "product of maxterms." The term "Sum of Products" (SoP or SOP) is widely used for the canonical form that is a disjunction (OR) of minterms. Its De Morgan dual is a "Product of Sums" (PoS or POS) for the canonical form that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JK Flip-flops
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems. Flip-flops and latches are used as data storage elements. A flip-flop is a device which stores a single ''bit'' (binary digit) of data; one of its two states represents a "one" and the other represents a "zero". Such data storage can be used for storage of ''state'', and such a circuit is described as sequential logic in electronics. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs). It can also be ...

Signetics
Signetics Corporation was an American electronics manufacturer specifically established to make integrated circuits. Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip. The company was bought by Philips in 1975 and incorporated in Philips Semiconductors (now NXP). History Signetics was started in 1961, by a group of engineers (David Allison, David James, Lionel Kattner, and Mark Weissenstern) who had left Fairchild Semiconductor. At the time, Fairchild was concentrating on its discrete component business (mostly transistors), and its management felt that by making integrated circuits (ICs) it would lose its customers. Signetics founders believed that ICs were the future of electronics (much like another contemporary Fairchild spinoff, Amelco) and wished to commercialize them. The name of the new company was coined from Signal Network Electronics. The venture was financed by a group organized t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
