how to use a data stream for a long simulation (10 seconds) to avoid to do sample by sample

I have a DSP block containing elements for receiving an MPX signal from  an FPGA, and a various treatments in order to extract relevant data (Left + Right, Left-Right). To do the simulation I inject one sample (1024 points of a signal) and i look what I have at the output. Now,  I would to do a simulation of longer duration (10 seconds). The DSP will load the first sample of 1024 points, then the second then the third ... up about 10 seondes. That way I could get a better idea of the output signal over a greater range and so it will be more representative of real-time.

I do not know if I was clear in my explanations, I hope I have been it, the aim is to make a simulation of a data stream rather than a single sample.
I hope you could help me find a solution thanking you in advance.
I use: VDSP 5.0 Update 10
