COMPLETE DIGITAL DESIGN A Comprehensive Guide to Digital Electronics and Computer System Architecture. Mark Balch. McGRAWHILL New York Chicago San Francisco Lisbon. Field programmable gate array Wikipedia. A field programmable gate array FPGA is an integrated circuit designed to be configured by a customer or a designer after manufacturing  hence field programmable. The FPGA configuration is generally specified using a hardware description language HDL, similar to that used for an application specific integrated circuit ASIC. Circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare. FPGAs contain an array of programmablelogic blocks, and a hierarchy of reconfigurable interconnects that allow the blocks to be wired together, like many logic gates that can be inter wired in different configurations. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR.

Technical designeditContemporary field programmable gate arrays FPGAs have large resources of logic gates and RAM blocks to implement complex digital computations. As FPGA designs employ very fast IOs and bidirectional data buses, it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resource allocation within FPGAs to meet these time constraints. How To Install Steering Stabilizer Chevy Tahoe. FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, partial re configuration of a portion of the design2 and the low non recurring engineering costs relative to an ASIC design notwithstanding the generally higher unit cost, offer advantages for many applications. Some FPGAs have analog features in addition to digital functions. The most common analog feature is programmable slew rate on each output pin, allowing the engineer to set low rates on lightly loaded pins that would otherwise ring or couple unacceptably, and to set higher rates on heavily loaded pins on high speed channels that would otherwise run too slowly. Also common are quartz crystal oscillators, on chip resistance capacitance oscillators, and phase locked loops with embedded voltage controlled oscillators used for clock generation and management and for high speed serializer deserializer SERDES transmit clocks and receiver clock recovery. Fairly common are differential comparators on input pins designed to be connected to differential signaling channels. A few mixed signal FPGAs have integrated peripheral analog to digital converters ADCs and digital to analog converters DACs with analog signal conditioning blocks allowing them to operate as a system on a chip. Such devices blur the line between an FPGA, which carries digital ones and zeros on its internal programmable interconnect fabric, and field programmable analog array FPAA, which carries analog values on its internal programmable interconnect fabric. HistoryeditThe FPGA industry sprouted from programmable read only memory PROM and programmable logic devices PLDs. PROMs and PLDs both had the option of being programmed in batches in a factory or in the field field programmable. However, programmable logic was hard wired between logic gates. In the late 1. Naval Surface Warfare Center funded an experiment proposed by Steve Casselman to develop a computer that would implement 6. Casselman was successful and a patent related to the system was issued in 1. Some of the industrys foundational concepts and technologies for programmable logic arrays, gates, and logic blocks are founded in patents awarded to David W. Page and Lu. Verne R. Peterson in 1. 98. Altera was founded in 1. EP3. 00 which featured a quartz window in the package that allowed users to shine an ultra violet lamp on the die to erase the EPROM cells that held the device configuration. Xilinx co founders Ross Freeman and Bernard Vonderschmitt invented the first commercially viable field programmable gate array in 1. XC2. 06. 4. 1. 01. The XC2. 06. 4 had programmable gates and programmable interconnects between gates, the beginnings of a new technology and market. The XC2. 06. 4 had 6. CLBs, with two three input lookup tables LUTs. More than 2. 0 years later, Freeman was entered into the National Inventors Hall of Fame for his invention. Altera and Xilinx continued unchallenged and quickly grew from 1. By 1. 99. 3, Actel now Microsemi was serving about 1. By 2. 01. 0, Altera 3. Actel 1. 0 percent and Xilinx 3. FPGA market. 1. 6The 1. FPGAs, both in sophistication and the volume of production. In the early 1. 99. FPGAs were primarily used in telecommunications and networking. By the end of the decade, FPGAs found their way into consumer, automotive, and industrial applications. Century DevelopmentseditA recentwhen trend has been to take the coarse grained architectural approach a step further by combining the logic blocks and interconnects of traditional FPGAs with embedded microprocessors and related peripherals to form a complete system on a programmable chip. This work mirrors the architecture created by Ron Perlof and Hana Potash of Burroughs Advanced Systems Group in 1. CPU architecture on a single chip called the SB2. Examples of such hybrid technologies can be found in the Xilinx Zynq 7. All Programmable So. C, which includes a 1. GHz dual core ARM Cortex A9 MPCore processor embedded within the FPGAs logic fabric or in the Altera Arria V FPGA, which includes an 8. MHz dual core ARM Cortex A9 MPCore. The Atmel FPSLIC is another such device, which uses an AVR processor in combination with Atmels programmable logic architecture. The Microsemi. Smart. Fusion devices incorporate an ARM Cortex M3 hard processor core with up to 5. B of flash and 6. B of RAM and analog peripherals such as a multi channel ADC and DACs to their flash based FPGA fabric. A Xilinx Zynq 7. All Programmable System on a Chip. An alternate approach to using hard macro processors is to make use of soft processorcores that are implemented within the FPGA logic. Nios II, Micro. Blaze and Mico. Many modern FPGAs are programmed at run time, and this is leading to the idea of reconfigurable computing or reconfigurable systems  CPUs that reconfigure themselves to suit the task at hand. Additionally, new, non FPGA architectures are beginning to emerge. Software configurable microprocessors such as the Stretch S5. FPGA like programmable cores on the same chip. Companies like Microsoft have started to use FPGA to accelerate high performance, computationally intensive systems like the data centers that operate their Bing search engine, due to the performance per Watt advantage FPGAs deliver.
