What do you have working so far? Do you have code written to at least read data from the module? If so, how are you doing it and are you just reading to the FPGA or are you transferring the data to the Real-Time (RT) controller through a DMA FIFO?
My recommendation would be to write your FPGA code to discard the first few bytes of data (just don't pass these first few bytes into the DMA FIFO). Once you have read the data on your RT controller using the DMA FIFO, use array manipulation to split the data as needed. There are a lot of array functions that should make this pretty easy once you have all of the data.
Again, let us know where you are currently and we'll try to help you out.
