multiplication of floating point numbers in tiva C

hey all,

instead of using inbuilt number format of tiva, i am using IQMath format ( multiplying the number with 16777216.0L) but i am able to do it using embedded C programming but my whole program is in inline assembly.so i created a .C file for converting number into IQ format containing function taking values & giving IQ values. do anyone knows how can i call that c function in my inline assembly language and pass the register values into it to get the IQ values??

if any alternate option is there please let me know to convert the values into IQ using assembly language.

    Hi,

    Still incomplete info - what is your toolchain? And why do you need to revert to IQ? Once in floating point you may scale it up or down using floating point operations, no need to revert to IQ (or at least explain why is this important to you).

    Did you read the bl_startup_ccs file? Dis you observed the #include X_file expression used?
