What is DSP and FPGA?

DSP functions are commonly implemented on two types of programmable platforms: digital signal processors and field programmable gate arrays (FPGAs). Digital signal processors are a specialized form of microprocessor, while FPGAs are a form of highly configurable hardware.

What is the use of DSP in FPGA?

A DSP is optimised for use of external memory, so a large data set can be used in the processing. FPGAs have a limited amount of internal storage so need to operate on smaller data sets. However FPGA modules with external memory can be used to eliminate this restriction.

What is digital filter in DSP?

In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. Digital filters can often be made very high order, and are often finite impulse response filters, which allows for linear phase response.

What are DSP blocks in FPGA?

With embedded hard digital signal processing (DSP) blocks, Stratix® series FPGAs are an ideal solution for high-performance, high-precision DSP applications. The DSP blocks are very power efficient and operate at far higher frequencies than the equivalent circuits in a soft implementation.

What are the advantages of FPGA?

Advantages. The main advantage of an FPGA, over the equivalent discrete circuit or an Application Specific IC (ASIC) is the ability to easily change its functionality after a product has been designed. In addition FPGA require a smaller board space and can be more energy efficient than the equivalent discrete circuit.

Is a DSP a microcontroller?

Abbreviated as MCU, µC or uC, a DSP microcontroller is a small computer that contains programmable output/input peripherals, a processor core, and memory on a single integrated circuit. It may also include a small amount of RAM and program memory. Microcontrollers are mainly designed for use in embedded applications.

Can FPGA replace DSP?

In recent years Field Programmable Gate Arrays (FPGAs) have gained a lot of traction in the real-time community, as a replacement for the traditional DSP solutions. FPGAs are indeed revolutionizing image and signal processing due to their advanced capabilities such as reconfigurability.

Why digital filter is used?

Digital filters are used for two general purposes: (1) separation of signals that have been combined, and (2) restoration of signals that have been distorted in some way. Analog (electronic) filters can be used for these same tasks; however, digital filters can achieve far superior results.

What are the advantages of digital filter?

Advantages of digital filter:

• Many input signals can be filtered by one digital filter without replacing the hardware.
• Digital filter have characteristic like linear phase response.
• The performance of digital filters does not vary with environmental parameter.
• Unlike analog filters; the digital filters are portable.

What is DSP used for?

Digital Signal Processing is used everywhere. DSP is used primarily in arenas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals.

What is a DSP slice?

The DSP slice consists of a multiplier followed by an accumulator. At least three pipeline registers are required for both multiply and multiply-accumulate operations to run at full speed. The multiply operation in the first stage generates two partial products that need to be added together in the second stage.

What are disadvantages of FPGA?

Drawbacks or disadvantages of FPGA The programming is not as simple as C programming used in processor based hardware. Moreover engineers need to learn use of simulation tools. ➨The power consumption is more and programmers do not have any control on power optimization in FPGA. No such issues in ASIC.

Which is FPGA implementation of efficient FIR filter?

FPGA is a prototype device which is used to implement simpler algorithm. removed by the filter. There are two types of digital filters. 1) Impulse Response) filter. Both FIR and IIR filters ha ve their characteristics. In most cases, the FIR filters have been used monitored.

What are the advantages of DSP on FPGAs?

The advantages of DSP on FPGAs are primarily related to the additional flexibility provided by FPGA reconfigurability. Not only can high-performance sys- tems be implemented relatively inexpensively, but the design and testcyclecanbecompletedrapidlydueto theeliminationof thein- tegrated circuit fabrication delays.

How are DSP functions such as FIR filters used?

DSP functions such as FIR filters and transforms are used in a number of applications such as communication and multimedia. These functions are major determinants of the performance and power consumption of the whole system. Therefore it is important to have good tools for optimizing these functions.

Which is another type of filter implementation of digital filters?

Another type of filter implementation of digital filters is FIR (finite impulse response). These do not use feedback and their output is only related to current and previous inputs. With regard to stability, FIR filters are always stable because their output is only related to inputs.
