Field Programmable Gate Array (FPGA) technology continues to show growth momentum. When Xilinx first created FPGA in 1984, it was still a simple glue logic chip, but now in signal processing and control applications, it has replaced custom application-specific integrated circuits (ASICs) and processors. Where is the success of this technology? This article will mainly introduce FPGA and focus on the unique advantages of FPGA.
1. What is FPGA?
At the highest level, FPGAs are reprogrammable silicon chips. Using pre-built logic blocks and reprogrammable wiring resources, users no longer need to use a breadboard or soldering iron to configure these chips to implement custom hardware functions. The user develops digital computing tasks in the software and compiles them into configuration files or bit streams, which contain information about the interconnection of components. In addition, the FPGA is fully reconfigurable, and when the user recompiles a different circuit configuration, it can immediately present brand new features. In the past, only engineers familiar with digital hardware design knew how to use FPGA technology. However, the rise of high-level design tools is changing the way FPGAs are programmed, among which emerging technologies can convert graphical block diagrams and even C code into digital hardware circuits.
The adoption of FPGA chips by all walks of life is due to the biggest advantage of FPGA's fusion of ASIC and processor-based systems. FPGA can provide the speed and stability of hardware timing, and does not require large-scale investment like the huge upfront cost of custom ASIC design. The flexibility of a reprogrammable silicon chip is comparable to software running on a processor-based system, but it is not limited by the number of available processor cores. Unlike the processor, FPGA is a true parallel implementation, so different processing operations do not need to compete for the same resources. Each independent processing task is equipped with a dedicated chip part, which can operate autonomously without being affected by other logic blocks. Therefore, when more processing tasks are added, the performance of other applications will not be affected.
2. Five advantages of FPGA technology
Performance, time to market, cost, stability, long-term maintenance
1) Performance—Using the advantages of hardware parallelism, FPGA breaks the mode of sequential execution and completes more processing tasks in each clock cycle, surpassing the computing power of the digital signal processor (DSP). The well-known analysis and benchmarking company BDTI released benchmarks showing that in some applications, the processing power per dollar of FPGA is many times that of DSP solutions. 2 Controlling input and output (I/O) at the hardware level provides faster response time and specialized functions to meet application requirements.
2) Cost-The non-recurring engineering (NRE) cost of custom ASIC design far exceeds the cost of FPGA-based hardware solutions. The huge investment in the initial stage of ASIC design shows that original equipment manufacturers need to transport thousands of chips every year, but more end users need custom hardware functions to realize the development of tens to hundreds of systems. The characteristics of programmable chips mean that users can save manufacturing costs and long delivery and assembly time. The requirements of the system will change from time to time, but the cost of changing the FPGA design is insignificant compared to the huge cost of ASCI.
3) Stability—The software tool provides a programming environment, and the FPGA circuit is the real “hard” execution process of programming. Processor-based systems often include multiple abstraction layers to plan tasks and share resources among multiple processes. The driver layer controls hardware resources, while the operating system manages memory and processor bandwidth. For any given processor core, only one instruction can be executed at a time, and processor-based systems are always facing the risk of strict time-limited tasks taking each other. The FPGA does not use an operating system, has true parallel execution and deterministic hardware dedicated to each task, which can reduce the possibility of stability problems.
4) Long-term maintenance—As mentioned above, FPGA chips are field-upgradable without the time and expense involved in redesigning ASICs. For example, digital communication protocols include specifications that can change over time, and ASIC-based interfaces may cause maintenance and forward compatibility difficulties. The reconfigurable FPGA chip can adapt to future modifications that need to be made. As the product or system matures, users do not need to spend time redesigning the hardware or modifying the circuit board layout to enhance functionality.
3. Summary
Higher-level tools continue to improve, bringing reprogrammable silicon chips to engineers and scientists of all professional levels, and the use of FPGA technology is becoming more and more widespread.

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:
I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).
I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).
I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).
Below are the approximate range of different power FM Transmitters. ( The range is diameter )
0.1W ~ 5W FM Transmitter ：100M ~1KM
5W ~15W FM Ttransmitter : 1KM ~ 3KM
15W ~ 80W FM Transmitter : 3KM ~10KM
80W ~500W FM Transmitter : 10KM ~30KM
500W ~1000W FM Transmitter : 30KM ~ 50KM
1KW ~ 2KW FM Transmitter : 50KM ~100KM
2KW ~5KW FM Transmitter : 100KM ~150KM
5KW ~10KW FM Transmitter : 150KM ~200KM
