Help me with NDT basic project using FPGA

ndt adc

hi all,,

i want a litel help in making my project on fpga ,,,

i m planing to make a samall scale model of NDT(non distructive testing)

here i giving general oveview,,

i will take a anolog signal from sensonr thn give it to the ADC ,,,

i want to store 1 saple per second and display it on LCD display ,,,

then i want to store the higest value i got in 1 min,

lowest value i got in 1 min ,,

and avg dc value of 1 min ,,,

the process is continuous ,,,,

and if possible i would like to generate some control signals and implment this on sparten 3 board with 2 sensors ,,,

waiting for reply asap

Re: NDT basic using fpga

atleast give me a basic idea ,,, so i can implement in vhdl code form ,,

the main prob i m facing is to store data at the output of adc and thn manuplating it ,,

Re: NDT basic using fpga

I don't know VHDL (and little Verilog for that matter...) but...

You could copy the incoming 8 bits (for example) into an array of registers, using a counter to increment the array index each time a sample is written in.

This worked for my ADC problem although the interface might differ:

okie here i think i need to go block by block ,,

so 1st what i need to say is i m suing sparten3E and i have on board 12 bit adc ,,,

here what i m going to do is intialy i m giving some signal on the analog input pin on the board and i want my adc to sample the valuses and store it somewhere ,,,

after that i m using 12 bit magnitude comparator and one another register having initial value of 0.

not i will take that 12 bit output and comapre it with initial value ,,, if my adc o/p is greater then initial value then i will store that o/p in my initial reg and so on ,,so at the end i vwill b heaving peak value in my register ,,,

so how can i do this ,,,

i have the code of magnitude comparator as its very easy but how can i implement this logic ,,,
