Hi all, Does Anybody help me to clear some concepts about MIPS 5kc? How to detect and set a MIPS 5kc chip working in 32bit or 64bit mode? or the chip can automatically enter proper mode when it fetchs an MIPS 32/64 instruction? Also, does MIPS 5kc have some 64bit instructions? Thanks a lot in advance, --Han __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
