What is FPGA chip

FPGA is the abbreviation of Field Programmable Gate Array. It is a programmable door array chip.Compared with ASIC, the biggest feature of FPGA is that it can be configured on -site configuration to achieve different functions, and has high flexibility and reinnerstability.

Features of FPGA

FPGA has the following characteristics:

Spartan-7 FPGA

1. High flexibility: Can meet different application needs, flexible and expanded.

2. Excellent performance: FPGA has a high clock frequency and calculation speed.

3. On -site configuration: Software configuration can be performed without physical changing the chip.

4. Low delay: FPGA does not need to compile instructions, which can directly control the hardware and reduce the delay of data operations.

5. Low power consumption: Since FPGA is a programmable chip, it does not require additional maintenance circuits, and the power consumption is low.

FPGA application

FPGA applications are widely used, mainly including:

1. Testing and measurement: FPGA is widely used in the field of testing and measurement, and is widely used in power testing, electronic measurement, and automatic testing.

2. Communication: FPGA can be used in satellite communication, wireless communication, data communication and other fields.

3. Image and video processing: The calculation speed of FPGA is fast, and image and video processing can be performed. It has application advantages in the fields of digital signal processing, image recognition, video coding, and decoding.

4. Industrial automation: FPGA can perform high -speed control operations, which can be used for intelligent instruments, industrial automation, robot control, etc.


The relationship between FPGA and test chip

Although FPGA is widely used in the field of testing and measurement, FPGA itself is not a test chip.

Test chip is a chip specially used for testing and analysis, which can transmit the test signal to the chip to be tested and analyze the feedback results.

In contrast, FPGA has been applied to tasks such as implementing hardware functions or performing digital signal processing.

FPGA’s application in testing

Although FPGA is not a test chip, it still has a wide range of applications in the test field.

1. Simulation: FPGA can be used for the simulation of electronic circuits, running simulation testing by loading the simulation model.

2. Point reuse: In design, FPGA can achieve pins, and the original complex signal reuse is simple.

3. Module test: The FPGA module can be used by key verification and testing to use the module to facilitate the test process.

4. Control system: FPGA is easy to write the control algorithm, which can be used to test the real -time control needs of the system.


Comparison of FPGA and ASIC

FPGA and ASIC are two different chip types, which are compared as follows:

1. Programming: FPGA can be configured on -site, ASIC cannot, only one -time solidification settings can be performed.

2. Power consumption: FPGA’s power consumption is higher than ASIC.

3. complexity: FPGA is suitable for small -scale design, ASIC is suitable for large -scale design.

4. Cost: The cost of FPGA is low, but the advantage of ASIC is that mass production under mass production can reduce the unit price.


In summary, although FPGA is widely used in the test field, it is not a test chip itself.As a programmable chip, FPGA has high flexibility and reassembly, suitable for a variety of different fields, and has great market potential.In practical applications, you need to choose according to specific needs.
