such as Single-Chip Microcomputers for Asembly language and C# ,so what is for Labview or G language
Modern version of LabVIEW do not. There once was a toolkit for creating C code for specific processors. But that is no longer supported. Otherwise, you are looking at using NI's sbRIO boards that have a Real Time controller and FPGA on it.
crossrulz, it still exists here: http://sine.ni.com/nips/cds/view/p/lang/nl/nid/209015
However the price tag (only available on direct request from NI) places this into a very different category than all the other single board IDEs.
