  • Re: efficient implementation of sqrt on C64x+

    Jogging. It is not optimal to use floating point representation directly on fixed point devices. Also, runtime support ibrary implementation for say floating point sqrt will not be the most optimal. I don't believe that is what is being used in VLIB.…

  • Re: question:using TMS320C64x DSP Library

    Resolved
    Did you look at the library here: http://focus.ti.com/docs/toolsw/folders/print/sprc542.html it lets you control the Q point for variables. I understand you need the support on 64x. The library currently only supports 64x+. But, if the library seems useful…

  • Re: CALCULATION TAKING TOO MUCH TIME??

    Resolved
    AC, Have you considered using Q formats with your floating point matrices. With Q format, you can convert your floating point value to appropriate fixed point value and after the matrix multiplication convert it back to floating point format. To convert…
