FPGA is a kind of programmable silicon chip, DSP is digital signal processing, when the system designer is facing the important question of whether to use FPGA or DSP in the architectural design stage of the project.

What is DSP on FPGA?

FPGA is a kind of programmable silicon chip, DSP is digital signal processing, when the system designer is facing the important question of whether to use FPGA or DSP in the architectural design stage of the project.

What is the difference between FPGA and DSP?

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 a DSP tile?

The DSP tile is four CLBs tall. Each DSP48 slice has a two-input multiplier followed by multiplexers and a three-input adder/subtracter. The multiplier accepts two 18-bit, two’s complement operands producing a 36-bit, two’s complement result.

What is the use of DSP?

Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like “add”, “subtract”, “multiply” and “divide” very quickly.

Is DSP programmable?

Although real-world signals can be processed in their analog form, processing signals digitally provides the advantages of high speed and accuracy. Because it’s programmable, a DSP can be used in a wide variety of applications.

Is DSP an ASIC?

The design of application-specific integrated circuits (ASIC) is at the core of modern ultra-high-speed transponders employing advanced digital signal processing (DSP) algorithms.

What is 4 tap FIR filter?

The 4-tap high speed FIR filter based on concept of Error Tolerance application is designed. The design runs at maximum sampling frequency of 505.05MHz and the lowest power consumption of 0.312mW. The two different combinations of adders and multipliers are used for the implementation of 4-tap low pass FIR filter.

What is Z transform in DSP?

In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain (z-domain or z-plane) representation. It can be considered as a discrete-time analogue of the Laplace transform (s-domain).

What are DSP instructions?

What software is used in FPGA design flow?

Fig. 7: FPGA Design Flow 2.3.3 Behavioral Simulation[20] D e s i g n o f a D i g i t a l S i g n a l P r o c e s s o r P a g e |17 After HDL designing, the code is simulated and its functionality is verified using simulation software, e.g. Xilinx ISE or ModelSim simulator.

Why implement a DSP on an FPGA?

Implementing this processor on a platform like FPGA gives us a powerful mechanism of implementing complex computations on a platform that provides a lot of resources and flexibility at a relatively lesser cost. Finally the DSP was implemented on a Spartan 3E FPGA kit. The output values were found to be consistent with the actual values.

What resources are available in an FPGA design?

Additional logic resources like ALUs, Decoders and memory may be available. The number of CLBs and I/Os required can easily be determined from the design but the number of routing tracks is different even within the designs employing the same amount of logic. Fig. 6: FPGA Architecture

What is the difference between ASIC design and FPGA design?

•Front-end design flow is almost the same for both •Back-end design flow optimization is different –ASIC design: freedom in routing, gate sizing, power gating and clock tree optimization. –FPGA design: everything is preplaced, clock tree is pre-routed, no power gating –Designs implemented in FPGAs are slower and consume more power than ASIC
