What is an FPGA?

Most times people wonder what FPGAs are all about. For novices, this might be very confusing.  FPGA refers to an Integrated Circuit. You can reconfigure the FPGA to carry out various tasks. For instance, engineers can reconfigure this board to work as a processor. Sometimes, it can also work as a Graphics Processing Unit (GPU).

This board can work according to how you reconfigure it. For instance, one can reprogram modern-day microcontrollers. These devices can function differently. One can reprogram FPGAs with various hardware designs. The function of FPGAs can change with the type of hardware design. You can make FPGAs work like Microcontrollers if you configure them.

FPGA means Field Programmable Gate Array. The field programmable means that designers can program FPGAs at the office and at home. Gate Array indicates that FPGAs have flip flops and logic gates. The flip flops and gates can be in Configurable Logic Blocks. FPGAs contain several CLBs. These things use programmable interconnect matrices.

FPGAs enable you to build your chip as you like. These boards are the framework for Digital Circuits. FPGAs feature programmable interconnects. You can rewire these interconnects programmatically. FPGAS utilizes Hardware Description Languages (HDL) to code some designs. SystemVerilog , Verilog, and VHDL are examples of HDL.

There are other languages like MATLAB, SystemC, and MyHDL. High-Level Synthesis is a popular method to program for FPGA.  This method carries out the design in a subset of C. The compiler then changes the design into the right Verilog code.

Codes with languages are changed into proprietary interconnect descriptions. The synthesis tools help to achieve this. The bitstream refers to the output file that has the interconnect description. Designers program the bitstream to the FPGA.

Benefits of Xilinx Kintex 7 FPGA
