IQMath library for C55x processors

Hello everyone,

Is there an IQMath library for C55x processors (similar to IQMath library for C64x processors)? If not, then is there any specific reason why TI has not

come up with a IQMath library for C55x processors. Also, I am wondering how does C55x performs floating-point operations. Any reference on these

will be very helpful.




  • Hello Abhishek,

    We do not have IQMath library for the C5000 family of DSPs. You can use Block Floating-Point techniques to handle floating point operations on the C55x core. General documentation on this technique is widely available.

    C55x-specific instructions are in the user guide for assembly language instruction set:

    The C5505 Teaching ROM  also has some information on it. Please see 05. Assembly V0.09.ppt. This can be downloaded from the TI University Programs webpage at
