I'm using CCS3.3. Is there some support library used to "active" this function?
after all, 6748 support both c67x+ float instructions and c64x+ fixed instructions.

Should I update my compiler? It seemed belong to the compiler's responsibility.
Can you expand on your question some more?
I'm not sure if you're trying to use legacy programs, or if you are trying to build a new program from scratch. If it's the later, the Instructions are available in the C674x DSP CPU and Instruction Set User's Guide available from the C6748 Product Page on TI.com

A compiler revision that supports the 6740 architecture will allow you to use C67x+ and C64x+ instructions in the same code base. To indicate that you are compiling/assembling for this architecture requires using the -mv6740 option. I believe 6.1.10 and later support this, so if you are using anything older than this (such as the default C6000 compiler that comes with CCSv3), then you should definitely download a new version from the Codegen tool download page.

It works!
A recommendation for people who want download new compile tools:
After installed cgt(codegen toos),you should open CCS's component manager, open build tools,
toggle 6200, 6400, 6700's compiler version to newer one
