Fpga data acquisition board

What devices use FPGA?
Specific applications using an FPGA include digital signal processing, biomedical instrumentation, device controllers, software-defined radio, random logic, medical imaging, computer hardware emulation, voice recognition, cryptography, filtering and communication encoding, and more..
Why FPGA is used for data acquisition?
The FPGA data acquisition module is designed by the VHDL and simulated by the ISE software.
This system has the advantage of being a simple unit with low power consumption and being used to collect data from different sensors..
A sample rate of 10.
1. MHz should be achievable, and even the smallest FPGA will have a lot of resource left for further processing
Data acquisition computer boards, also known as DAQ cards, are self-contained printed circuit boards (PCBs) that plug into backplanes, motherboards, or interface directly with a computer.
They either have direct inputs or receive analog and digital inputs from signal conditioners, modules, relays or sensors.
Real-World Applications of the FPGAs
Digital Signal Processing (DSP): FPGAs are widely used for high-performance DSP applications like image and video processing, audio processing, and wireless communication.
Their parallel processing capabilities and reconfigurability make them ideal for real-time signal processing.

Mar 15, 2020Data Acquisition using FPGA I need to build a DAQ device which can read 16 channels of 1024 samples ( each sample being 8 bit wide) at 80MHz.

FPGA, as the core of the data acquisition system, collects and stores the data. This system is divided into three modules: the front-end signal processing

Design Considerations

The design consideration would be based on the bandwidth of ADS 1252 which is around 40-KHZ data rates

FPGA Logic Design Functional Description

The VHDL code is generated using the system generator toolbox [4] available from Xilinx which reduces the development time and also helps in

FIFO Depth Calculation

The design might run the risk of data overflow/underflow if a FIFO of optimum depth is not incorporated

How does a FPGA work?

From a high-level perspective, the FPGA combines data from everything that’s connected to the acquisition board, attaches a common timestamp, and sends it to the computer via USB

How does an ADC board communicate with a FPGA board?

The ADC board is interfaced to the FPGA board via a PMOD (or Peripheral Module interface) connector and communicates through an SPI-like communication protocol

The difference between the standard SPI protocol and this protocol is manifested in the pin arrangement on this PMOD

What is data acquisition in FPGA?

Data acquisition inside FPGA is done at a speed of 250 MHz clock frequency

ADC provides the reference clock to the FPGA for each channel (I and Q) and one has to latch the samples in on every rising edge of the clock pulse

Initially DDR data is sent by the ADC which is converted to SDR data by using the IDDR primitive
