  • RE: How to build DSPLIB for C64x+

    Hi, Thanks for your post. Basically, MATHLIB is not a fixed point computation library, so, obviously, you cannot see math libraries for fixed point c64x+ core devices. May be, you could use the ELF version of the C64X+ DSP libraries ( 0042.ELF_libraries…

  • RE: Need the accuracy, resolution and tolerance values of Newton-Raphson inverse algorithm and Maclaurin series.

    Resolved
    Hi Prasad, Thanks for your post. To get higher precision results, Newton-Raphson interpolation would be recommended. For RSQRxP instructions to calculate 1/sqrt(v), Newton-Raphson interpolation would improve the mantissa precision to 2-16, and one…
