Stratix is a brand of FPGA products developed by Intel, Programmable Solutions Group (former Altera). Other current FPGA product lines include e.g. Agilex, Arria and Cyclone families.
Stratix FPGAs are typically programmed in hardware description languages such as VHDL or Verilog, using the Intel Quartus Prime computer software.
Intel FPGAs have been used in automotive, optical imaging, memory, data processing [1] [2] and computing applications.
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term 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, but this is increasingly rare due to the advent of electronic design automation tools.
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.
A front-side bus (FSB) is a computer communication interface (bus) that was often used in Intel-chip-based computers during the 1990s and 2000s. The EV6 bus served the same function for competing AMD CPUs. Both typically carry data between the central processing unit (CPU) and a memory controller hub, known as the northbridge.
Reconfigurable computing is a computer architecture combining some of the flexibility of software with the high performance of hardware by processing with very flexible high speed computing fabrics like field-programmable gate arrays (FPGAs). The principal difference when compared to using ordinary microprocessors is the ability to make substantial changes to the datapath itself in addition to the control flow. 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.
In electronics, pin-compatible devices are electronic components, generally integrated circuits or expansion cards, sharing a common footprint and with the same functions assigned or usable on the same pins. Pin compatibility is a property desired by systems integrators as it allows a product to be updated without redesigning printed circuit boards, which can reduce costs and decrease time to market.
Altera Corporation was a manufacturer of programmable logic devices (PLDs) headquartered in San Jose, California. It was founded in 1983 and acquired by Intel in 2015.
Programmable Array Logic (PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic Memories, Inc. (MMI) in March 1978. MMI obtained a registered trademark on the term PAL for use in "Programmable Semiconductor Logic Circuits". The trademark is currently held by Lattice Semiconductor.
JTAG is an industry standard for verifying designs and testing printed circuit boards after manufacture.
In computer architecture, 36-bit integers, memory addresses, or other data units are those that are 36 bits wide. Also, 36-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size. 36-bit computers were popular in the early mainframe computer era from the 1950s through the early 1970s.
A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The main building block of the CPLD is a macrocell, which contains logic implementing disjunctive normal form expressions and more specialized logic operations.
Nios II is a 32-bit embedded processor architecture designed specifically for the Altera family of field-programmable gate array (FPGA) integrated circuits. Nios II incorporates many enhancements over the original Nios architecture, making it more suitable for a wider range of embedded computing applications, from digital signal processing (DSP) to system-control.
Nallatech is a computer hardware and software firm based in Camarillo, California, United States. The company specializes in field-programmable gate array (FPGA) integrated circuit technology applied in computing. As of 2007 the company's primary markets include defense and high-performance computing. Nallatech was acquired by Interconnect Systems, Inc. in 2008, which in turn was bought by Molex in 2016.
Intel Quartus Prime is programmable logic device design software produced by Intel; prior to Intel's acquisition of Altera the tool was called Altera Quartus Prime, earlier Altera Quartus II. Quartus Prime enables analysis and synthesis of HDL designs, which enables the developer to compile their designs, perform timing analysis, examine RTL diagrams, simulate a design's reaction to different stimuli, and configure the target device with the programmer. Quartus Prime includes an implementation of VHDL and Verilog for hardware description, visual editing of logic circuits, and vector waveform simulation.
Interlaken is a royalty-free interconnect protocol.
A multi-gigabit transceiver (MGT) is a SerDes capable of operating at serial bit rates above 1 Gigabit/second. MGTs are used increasingly for data communications because they can run over longer distances, use fewer wires, and thus have lower costs than parallel interfaces with equivalent data throughput.
Virtex is the flagship family of FPGA products developed by Xilinx, a part of AMD. Other current product lines include Kintex (mid-range) and Artix (low-cost), each including configurations and models optimized for different applications. In addition, Xilinx offers the Spartan low-cost series, which continues to be updated and is nearing production utilizing the same underlying architecture and process node as the larger 7-series devices.
Tabula was an American fabless semiconductor company based in Santa Clara, California. Founded in 2003 by Steve Teig, it raised $215 million in venture funding. The company designed and built three dimensional field programmable gate arrays and ranked third on the Wall Street Journal's annual "Next Big Thing" list in 2012.
Achronix Semiconductor is an American fabless semiconductor company based in Santa Clara, California with an additional R&D facility in Bangalore, India, and an additional sales office in Shenzhen, China. Achronix is a diversified fabless semiconductor company that sells FPGA products, embedded FPGA (eFPGA) products, system-level products and supporting design tools. Achronix was founded in 2004 in Ithaca, New York based on technology licensed from Cornell University. In 2006, Achronix moved its headquarters to Silicon Valley.
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 logic gates.
Agilex is a brand covering several families of FPGA products developed by Intel Programmable Solutions Group, and are the FPGA products developed by Intel after the acquisition of Altera. The initial family of Agilex FPGAs began shipping in 2019 and are built using Intel 10nm silicon process. Agilex FPGAs are typically programmed in hardware description languages such as VHDL or Verilog, using the Intel Quartus Prime computer software. Higher level design languages, such as SYCL, are supported as well.
