Field Programmable Gate Array (FPGA) is a kind of integrated circuit which contains a large number of logic gates and it can be reconfigured without changing hardware structure. It is usually used to implement complex logic functions which are difficult to implement in discrete components.

XC4VFX12-12FFG668C is an embedded FPGA. It is a virtex-4 FPGA, which is designed with the latest process technology and features higher speed, larger capacity and improved power consumption.XC4VFX12-12FFG668C is suitable for high-end applications, such as high-speed signal processing, communications and control systems.

Working Principle

FPGA technology is based on the basic circuit structure of Field Programmable Logic Array (FPLA). It is composed of multiple Array Blocks (ABs). Each ABs contains hundreds of logic cells that are connected by programmable interconnects. In FPGA, logic cells are implemented with lookup tables (LUTs). LUTs are programmable logic devices that can be programmed to perform different logic functions for each logic cell. The signals outputted by logic cells are stored in the internal registers, and the stored signals are connected by the programmable interconnects.

Therefore, the XC4VFX12-12FFG668C FPGA can be used to implement complex logic functions in the embedded applications. The embedded programs can be written in languages like VHDL or Verilog. After the programs have been written, the hardware design can be synthesized and the logic functions can be implemented in the FPGA logic cells. Then, the data communication between the logic blocks can be configured through the programmable interconnects. Finally, the configuration can be downloaded to the XC4VFX12-12FFG668C FPGA for operation.

In summary, XC4VFX12-12FFG668C is an embedded FPGA, which can be used in high-end applications. Its working principle is based on FPLA’s basic circuit structure, and the logic functions can be implemented in the logic cells. The data communication between different logic blocks can be configured through the programmable interconnects.
