Implementation of the onboard ADC and DAC on the Spartan 3E FPGA platform.

摘要

The objective of this project is to first interface the on board ADC and DAC available in the Spartan 3E FPGA platform, so that the real signals too can be processed by the FPGA board. Thus first of all, the ADC was interfaced and the results were observed via ChipScope Pro. Then the DAC was interfaced and checked if it was working or not. Finally both were operated together, where registers were used to store the values of the digital data obtained from the ADC and then sent to the DAC for the reconstruction of the original signal, which could be observed via a DSO.udADC is a prime requirement whenever real-world signals come into play, hence interfacing the ADC is of great use and help in using the real-world signals for our use and furtherudprocessing to extract vital information. DAC also aids in the said process similarly.udThe basic aim being that a given input signal should output exactly or nearly exactly the given input signal after having it passed through the ADC and the DAC.
