NPPI v7.5 can not run on GTX1070 card

I found nppiMalloc_XXX() in nppi v7.5 can not run on my GTX1070 card,when my program call these funtions,the program is stalled,but there is no problem for call these functions in nppi v8.0,so is it means I must use CUDA SDK v8.0 if my program need nppi library on Pascal GPU?
