FPGA (Field Programmable Gate Array) is an integrated circuit that can be programmed by a user to perform custom logic functions. The programming is typically done using a hardware description language such as VHDL or Verilog. FPGAs are used in embedded system applications where the logic must be optimized for the changing requirements of the system.

One example of an FPGA is the HC20K400FC672, which is a Xilinx Spartan-6 part. The FPGA has 16 Configurable Logic Blocks (CLBs) of 6 input/10 output levels. Each CLB contains up to 4 look-up tables (LUTs) and 8 Flip-Flops (FFs), with a total of 256 LUTs and 512 FFs. The device also has 72 Bit slices with 4-input carry logic, giving the device up to 288 Kbits of memory.

The HC20K400FC672 is used in a variety of embedded system applications, including automotive, aerospace, factory automation, medical and consumer electronics. It is especially well-suited for video applications, where it can provide the necessary data capture and frame processing. For example, in automotive rear-view camera systems the FPGA can receive data from the camera, then process it to form the image that will be displayed on the rear-view monitor.

The working principle of the HC20K400FC672 is based on configurable logic blocks (CLB). CLBs consist of a collection of logic elements such as Look-Up-Tables (LUTs) and Flip-Flops (FFs). These elements are connected together to form a Logic Array Block (LAB). The CLB can then be programmed by the user to perform custom logic functions.

The user defines the logic function to be performed in the LAB. The CLB then configures the logic elements in the LAB according to the user’s logic definition. Once this configuration is complete, the CLB can execute the logic function as defined by the user. This allows the user to quickly implement custom logic functions in the FPGA with minimal time and effort.

In conclusion, the HC20K400FC672 is a versatile FPGA designed for use in embedded applications. It is ideal for use in video applications where data capture and frame processing are required. The working principle of the HC20K400FC672 is based on configurable logic blocks which can be programmed by the user to perform custom logic functions. This makes the HC20K400FC672 a great choice for embedded system applications.
