Complex Multiplication in C6474 ?

Hello ,

I'm using EVM C6474 ..& im  executing a C language code for complex matrix multiply ...

To improve the effeciency of my code .. I want to know if there are some ways to mix Assembly instructions with C code and use 'c declared variables' in asm

Another problem is that the  assembly instruction  (CMPY : Complex Multiply) can only handle 16-bits inputs, while I've 32-bit ones. Is there any way to do 32-bit complex mutiply exploiting this assembly instruction

Thank you in advance.

    Are you certain that you need the extra range or resolution of 32-bit numbers for your matrix values? You can take advantage of CMPY if you use 16-bit numbers, as you have already determined; the CMPY* instructions will not work for 32-bit numbers.

    Please go to the TI Wiki Pages and do a search for C6000 Optimization; you will find several useful topics there, including a set of Workshop materials and a page with links for verious optimization techniques.

    For specific information on mixing C and assembly, please refer to the C6000 Optimizing Compiler User's Guide for the version of the Code Generation Tools you are using.

    Regards,
