FPGAs for signal processing Because, unlike in DSPs, only application-specific and correspondingly optimized arithmetic units are implemented in an FPGA, the solutions are particularly cost-effective and efficient.

So, Why can an FPGA be faster than an CPU? In essence it's because the FPGA uses far fewer abstractions than a CPU, which means the designer works closer to the silicon. He doesn't pay the costs of all the many abstraction layers which are required for CPUs.

Efficiency and Power: FPGAs are well-known for their power efficiency. A research project done by Microsoft on an image classification project showed that Arria 10 FPGA performs almost 10 times better in power consumption. ... This feature allows GPUs to be more power efficient than CPUs.

Through the use of high-resolution counters, the duty cycle of a square wave is modulated to encode a specific analog signal level. The PWM signal is still digital because, at any given instant of time, the full DC supply is either fully on or fully off.

FPGAs are power efficient when compared to GPU. FPGAs are basically hardware implemented therefore hardware is faster than software. GPUs are historical and they are basically power hogs which is problematic.

Essentially, an FPGA is a hardware circuit that a user can program to carry out one or more logical operations. Taken a step further, FPGAs are integrated circuits, or ICs, which are sets of circuits on a chip—that's the “array” part.

While PLCs are the go-to for the Industrial Industry, that doesn't mean that an Arduino can't be useful for the Industrial industry. ... The Arduino is great for small-form solutions that you can build yourself at home, but it can also be utilized on large-scale projects when used to keep track of data and processes.

VHDL is a hardware description language(HDL) . It is used for implementing the hardware circuit. C can only handle sequential instructions. VHDL allows both sequential and concurrent executions.

FPGAs usually cost more upfront than a microprocessor or ASIC. Microprocessors have a lower unit cost and higher volume of production. On the other hand, an FPGA can be reprogrammed over and over for different tasks, making them very cost efficient by avoiding recurring expenses.

FPGA devices provide a reconfigurable DSP solution for various DSP applications. FPGA devices incorporate a variety of embedded features such as embedded processors, DSP blocks, and memory blocks. ... The DSP Builder tool flow can also be combined with the SOPC Builder tool flow for implementing a complete DSP system.

While PLCs are the go-to for the Industrial Industry, that doesn't mean that an Arduino can't be useful for the Industrial industry. One task that Arduino is great for is collecting data, so if you need to collect temperature and humidity, you can easily insert the Arduino to monitor many variables.

The DFT is one of the most powerful tools in digital signal processing which enables us to find the spectrum of a finite-duration signal. There are many circumstances in which we need to determine the frequency content of a time-domain signal. ... This can be achieved by the discrete Fourier transform (DFT).

The simple answer to this question is that the fast Fourier transform (FFT) is important because it is an efficient algorithm for computing the discrete Fourier transform (DFT). It is fast, just as the name indicates, in computing something that seems slow at first sight.

In essence it's because the FPGA uses far fewer abstractions than a CPU, which means the designer works closer to the silicon. ... FPGAs have fewer abstractions and so they can be faster and more power efficient but difficult to program for.

Block RAM stores large amounts of data while distributed RAM stores small chunks of data across the logic path,so when you are using larger blocks of memory or RAM, Block RAM is faster as compared to distributed RAM otherwise the FPGA blocks will take too time to respond and unnecessary space is taken up by memory.
