ARM selects XJTAG for RealView development tools debug and test
“ ARM, the world’s leading semiconductor intellectual property (IP) supplier, has reduced the time and cost of
developing its range of RealView development tools by using the XJTAG boundary scan development system to
improve and speed up the process of debugging and testing its high density, multi-layer development boards.
