Reciprocal (RCPSP) C6748 (OMAP-L138) instruction MATLAB model

Hi.

I am looking for MATLAB model for the reciprocal approximation assembler instruction (rcpsp) that is used in C6748 DSP.

 

Thanks, Alexey.

    Can you please provide more detail on the end application and why you need a Matlab equivalent?

    Please note that rcpsp is not supposed to be used in isolation. It is used by the RTS/fastRTS kernels to implement the reciprocal implementation.

    Thanks,
    Gaurav

    Gaurav,

    I am implementing some communication algorithms, and in few of the algorithms, approximate reciprocal (with 8 bits mantissa accuracy) is more than enough. In order to be able to compare the DSP simulation results with MATLAB results, I need Matlab equivalent for this approximation.

     

    Thanks, Alexey.
