Embedded - FPGAs Control System

Field Programmable Gate Arrays (FPGAs) are essential components in current embedded systems. With the ever-increasing complexity of embedded systems, controlling all of their components has become more complicated, requiring more sophisticated pathways and mechanisms to operate. FPGAs are integrated circuits which are programmable and flexible, allowing systems to be designed and tailored to specific functional requirements. This article will discuss the application field and working principle of an HC1S80F1020AYR, a 4-bit configurable FPGA.

Principles of FPGAs

FPGAs are the closest form of reconfigurable logic circuits for embedded system control. The essential principle of FPGA is that, instead of having a countless number of circuit elements (as there would be in board-level electronics) that are wirings and behaviours made in advance and are also called "combinatorial elements", FPGAs build up all these elements on an integrated circuit as an array. The user configures the behaviour of each cell individually, disconnecting it from its surroundings when necessary, and connecting it back when the design is done. The user can also configure interconnections and configure the combination of cells. By programming the FPGA in software and uploading the designed schematic to the device via the JTAG, it can be used as a control system. Furthermore, FPGAs are typically equipped with a set of fixed circuitry, such as RAM and input/output (I/O) pins. FPGAs also have a large number of registers and memory blocks, as well as a clock generation circuit, all of which can be used for designing complicated Control systems.

Application Field of HC1S80F1020AYR

The HC1S80F1020AYR is a 4-bit configurable FPGA from Haizol. It offers flexibility, reliability, and speed. The HC1S80F1020AYR has several advantages combined with its programmability, making it suitable for different applications in the embedded control field.Firstly, the HC1S80F1020AYR is designed with a dedicated logic cell array, allowing it to achieve a high-density design with a maximum of 4,000 logic cells. This FPGA is also capable of delivering faster clock speeds with a flexible clock network and features a built-in phase locked loop (PLL). This makes it ideal for applications that require fast response times and precise timing.Another important feature of the HC1S80F1020AYR is its multiple I/O interfaces. It supports LVDS, LVPECL, PECL, and USB. This allows it to interface with a wide range of external devices and make it more suitable for complicated embedded control system applications.Finally, the HC1S80F1020AYR is equipped with error-detection and correction (EDAC) circuitry. This provides protection from errors that may occur during operation, ensuring reliable and accurate control.

Working Principle of HC1S80F1020AYR

The HC1S80F1020AYR is capable of controlling and managing complicated Control systems by configuring the behavior of its cell array. When theHC1S80F1020AYR is first powered on, the cells will be placed in a default state, and the user can then configure each cell individually.This is done using a graphical programming language such as VHDL or Verilog. Each cell in the array can be assigned its own operation – whether it is an input, an output, or an internal operation. The user can then assign connections between the cells, specify their operations, and program the clock network.Once the FPGA has been programmed, the user can then upload the schematic to the device via the JTAG. The design is then presented to the integrated logic cell array, enabling the user to have a full control system in hand.

Conclusion

The HC1S80F1020AYR is a highly suitable FPGA for embedded control system applications. It offers a high-density design, fast clock speeds, multiple I/O interfaces, and an error-detection and correction circuitry. Its programmability also makes it easier for users to set up and control their applications. As such, it is a great choice for demanding control applications.
