thread576-86842: need to access data from previous time samples

hi, i have same problem. I am preparing signal A to D -> D to A proccesing line. But I restoring samples faster than I sampling analog signal. I would like to collect for example 10 samples and then start reconstruction of orignal signal. I was trying to use memory stored data ( read, write ) blocks.
I delay  execution of memory read block but with this method i am still able to read, only present samples( the samples which were collected via memory write block before execution of memory read block are unaccesible).Please advise.

RE: signal processing

thank you Greg for quick answer.

I appreciate your idea, but my converter is asynchronous and I am not able to predict the delay.

This is my problem:

In DA part of my converter when I need access to second sample after proccesing first one, the second sample is unavaible because AD part doesn't complete producing this sample.

I am a little bit desparte so i try to save all samples to untitled.mat file and in the second instance of simulink restoring this data, but in this case restored data have different resolution.

I am about to exhaustion.

Any other sugestion?
