FPGA
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] |

Reconfigurable Computing
Reconfigurable computing is a computer architecture combining some of the flexibility of software with the high performance of hardware by processing with flexible hardware platforms like FPGA, field-programmable gate arrays (FPGAs). The principal difference when compared to using ordinary microprocessors is the ability to add custom computational blocks using FPGAs. On the other hand, the main difference from custom hardware, i.e. application-specific integrated circuits (ASICs) is the possibility to adapt the hardware during runtime by "loading" a new circuit on the reconfigurable fabric, thus providing new computational blocks without the need to Semiconductor device fabrication, manufacture and add new Integrated circuit, chips to the existing system. History The concept of reconfigurable computing has existed since the 1960s, when Gerald Estrin's paper proposed the concept of a computer made of a standard processor and an array of "reconfigurable" hardware. The main process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Logic Block
In computing, a logic block or configurable logic block (CLB) is a fundamental building block of field-programmable gate array (FPGA) technology. Logic blocks can be configured by the engineer to provide reconfigurable computing, reconfigurable logic gates. Logic blocks are the most common FPGA architecture, and are usually laid out within a logic block array. Logic blocks require I/O pads (to interface with external signals), and routing channels (to interconnect logic blocks). Programmable logic blocks were invented by David W. Page and LuVerne R. Peterson, and defined within their 1985 patents.Google Patent Search,Re-programmable PLA. Filed January 11, 1983. Granted April 2, 1985.

Microsemi
Microsemi Corporation was an Aliso Viejo, California-based provider of semiconductor and system solutions for aerospace & defense, communications, data center and industrial markets. In February 2018, it was announced that Chandler, Arizona-based Microchip Technology was acquiring the company for over US$10 billion, pending regulatory approval. In May 2018, it was announced that Microchip had completed its acquisition of Microsemi. In August 2018, Microchip discovered that Microsemi shipped large orders to distributors on discount before the closing of the acquisition and had a culture of excessive extravagance, casting some doubt on the future prospect of the acquisition. History 1959 to 1970: Early years Microsemi was founded in February 1959 in Culver City, California as MicroSemiconductor. It incorporated in Delaware on September 27, 1960.

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, the function of a PLD is undefined 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 uncomm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application-specific Integrated Circuit
An application-specific integrated circuit (ASIC ) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use, such as a chip designed to run in a digital voice recorder or a high-efficiency video codec. #Application-specific standard product, Application-specific standard product chips are intermediate between ASICs and industry standard integrated circuits like the 7400 series or the 4000 series. ASIC chips are typically semiconductor device fabrication, fabricated using metal–oxide–semiconductor (MOS) technology, as MOS integrated circuit chips. As feature sizes have shrunk and Electronic design automation, chip design tools improved over the years, the maximum complexity (and hence functionality) possible in an ASIC has grown from 5,000 logic gates to over 100 million. Modern ASICs often include entire Central processing unit, microprocessors, memory blocks including Read-only memory, ROM, Random-access memory, RAM, ...

Hardware Description Language
In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs). A hardware description language enables a precise, Formal language, formal description of an electronic circuit that allows for the automated analysis and Electronic circuit simulation, simulation of the circuit. It also allows for the Logic synthesis, synthesis of an HDL description into a netlist (a specification of physical electronic components and how they are connected together), which can then be Place and route, placed and routed to produce the Mask set, set of masks used to create an integrated circuit. A hardware description language looks much like a programming language such as C (programming language), C or ALGOL; it is a textual description consisting of expressions, statements and c ...

Gate Array
A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a semiconductor device fabrication, prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, Flip-flop (electronics), flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory. It was popular during the upheaval in the semiconductor industry in the 1980s, and its usage declined by the end of the 1990s. Similar technologies have also been employed to design and manufacture analog, analog-digital, and structured arrays, but, in general, these are not called gate arrays. Gate arrays have also been known as uncommitted logic arrays ('ULAs'), which also offered linear circuit functions, and ''semi-custom chips''. History Development Gate arrays had several concurrent development paths. Ferranti in the UK pioneered commercializing bipolar transistor, bipolar ULA technology, offering c ...

Embedded System
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems.
