FPGAs contain dedicated global and regional routing networks for clock and reset, typically implemented as an H tree, so they can be delivered with minimal skew. FPGAs may contain analog phase-locked loop or delay-locked loop components to synthesize new clock frequencies and manage jitter.
Field-programmable gate array prototyping (FPGA prototyping), also referred to as FPGA-based prototyping, ASIC prototyping or system-on-chip (SoC) prototyping, is the method to prototype system-on-chip and application-specific integrated circuit designs on FPGAs for hardware verification and early software development.
FPGAs use a grid of logic gates, and once stored, the data doesn't change, similar to that of an ordinary gate array. The term field-programmable means the device is programmed by the customer, not the manufacturer. FPGAs and gate arrays are similar but gate arrays can only be configured at the factory during fabrication. [11] [12] [13]
Virtex is the flagship family of FPGA products currently developed by AMD, originally Xilinx before being acquired by the former. [1] Other current product lines include Kintex (mid-range) and Artix (low-cost), each including configurations and models optimized for different applications. [2]
iCE is the brand name used for a family of low-power field-programmable gate arrays (FPGAs) produced by Lattice Semiconductor.Parts in the family are marketed with the "world's smallest FPGA" tagline, and are intended for use in portable and battery-powered devices (such as mobile phones), [1] where they would be used to offload tasks from the device's main processor or system on chip.
FpgaC is a silicon compiler, which produces digital circuits that will execute compiled language computer programs.The digital circuits produced may use FPGAs or CPLDs as the target processor for reconfigurable computing, or even ASICs for dedicated software applications.
The Spartan-7 family, built on the same 28nm process used in the other 7-Series FPGAs, was announced in 2015, [155] and became available in 2017. [156] Unlike the Artix-7 family and the "LXT" members of the Spartan-6 family, the Spartan-7 FPGAs lack high-bandwidth transceivers. [168]
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).
