A field programmable gate array is a digital blank slate that can be used for a variety of purposes. The biggest difference between an FPGA digital chip and an application-specific integrated circuit is that the circuit design is fixed in an application-specific integrated circuit whereas an FPGA chip can be reconfigured as many times as you want.

A field programmable gate array is a digital blank slate that can be used for a variety of purposes. The biggest difference between an FPGA digital chip and an application-specific integrated circuit is that the circuit design is fixed in an application-specific integrated circuit whereas an FPGA chip can be reconfigured as many times as you want.

Black Digital Slate

As mentioned in the beginning, it is blank digital slate which means you can use an FPGA for almost anything. Since you need to create the actual digital circuit to use an fpga, you can use it to emulate almost anything depending on the complexity of the circuit. In other words, an FPGA chip provides you control over the hardware. You can design a digital circuit to use an FPGA chip as a microprocessor.

Use Digital Chips For Prototyping

In fact, the biggest companies known for making processors use these digital chips for prototyping before actually creating ASICs. As far as the typical uses of FPGA is concerned, these digital chips are mostly used in signal processing systems as well as an image processing systems. Also, solutions that require development of custom SoC use FPGA chips.

Advantage Of Digital Chips

The biggest advantage of these digital chips is that these can be configured to create any kind of digital circuit. You can program the hardware and create software to work on that hardware. These digital chips are also great for hobbyists as these chips allow hobbyists to create their own digital circuits based on their needs at an affordable price. An application-specific integrated circuit costs millions of dollars but an FPGA digital chip is affordable.

FPGA Different From Microcontrollers

A typical FPGA chip can contain up to 100,000 logic blocks. Many people who have never heard of FPGA often confuse them for microcontrollers. These are very different from microcontrollers. The microcontroller has a chip already designed and you will need to write some software in order to perform the required functions. With the microcontroller, you control the software. On the other hand, an FPGA chip provides you complete control over the hardware. You have complete freedom to configure an FPGA chip to behave as a multicore processor or something else.

It is also pertinent to mention here that the configuration is stored in RAM in an FPGA chip and not flash. In simple terms, it means that the FPGA chips lose their confirmation once they lose power and need to be reconfigured every time. However, this also provides the flexibility that allows FPGA chips to be used for testing purposes. For detail information visit http://www.directics.com/fpga-programming/
