Flatten floating point on FPGA for multichannel DMA

Hi,

We have a large FPGA application on a cRIO with 3 DMAs and are trying to transfer mutliple channels of data through a target-to-host DMA.  We have a large variety of types (U8 to floating point) to support but I can't seem to find a way to flatten (extract the bytes of) the floating point quantities to stuff into the DMA.  I don't want to use a second DMA. 

Any tips?

thanks,

Steve
