FwStatus   fwsInvSqrt_64f_A53 ( const Fw64f * pSrcFw64f * pDstint len );

Parameters

len   Specifies the number of elements in a buffer.
pDst   Pointer to a destination buffer.
pSrc   Pointer to a source buffer.

Description

These functions step through vector elements in a source buffer, calculate the inverse square root of each element, and write the results to a destination buffer.
