AWR2944PEVM: AWR2944 SDK：DPU data problem

for AWR2944P SDK version 4.7.0.1，i use DPU like rangeproDDMA. This DPU use HWA run rangeprocDDMA_testAdcDataIn_awr2944.bin adc data and get 1DFFT output, and then use this data compare with rangeprocDDMA_testResult_awr2944.bin to show that  HWA works well. But when i use adc data that from rangeprocDDMA_testAdcDataIn_awr2944.bin  to run in MATLAB and get 1DFFT data,  compare with rangeprocDDMA_testResult_awr2944.bin, it look like not equal.   

so can you tell me is rangeprocDDMA_testResult_awr2944.bin means decompress 1DFFT data? or compress 1DFFT data?       and if this is the decompress 1DFFT data, why not equal to the result that run from rangeprocDDMA_testAdcDataIn_awr2944.bin adc data?

i want to use DPU to test my configurtion. please.
