Basic Concepts

This chapter provides an overview of the information contained in the functional descriptions.

Framewave functional descriptions include the following types of information.

Parameter Glossary

Signal processing library function definitions use the following parameters.

dstLen   Specifies the number of elements in destination buffer(this will be the length of auto-correlation)
hint   Hints whether to choose a fast or accurate computation algorithm.
len   Specifies the number of elements in a buffer.
lenFind   Length of the substring.
level   Specifies a threshold level.
levelGT   Specifies a threshold level for greater-than comparison.
levelLT   Specifies a threshold level for less-than comparison.
pDp   Pointer to the destination buffer that contains the dot product of the source buffers.
pDst   Pointer to a destination buffer.
pDst1   Pointer to destination buffer one.
pDst2   Pointer to destination buffer two.
pFind   Pointer to the substring.
pIndex   Pointer to the index of the result.
pIndx   Pointer to the destination buffer that contains the index of the maximum or minimum value in the source buffer.
pMax   Pointer to the destination buffer that contains the maximum value in the source buffer.
pMaxAbs   Pointer to the destination buffer that contains the maximum absolute value in the source buffer.
pMaxIndx   Pointer to the destination buffer that contains the index of the maximum value in the source vector.
pMean   Pointer to the destination buffer that contains the mean of the values in the source buffer.
pMin   Pointer to the destination buffer that contains the minimum value in the source buffer.
pMinAbs   Pointer to the destination buffer that contains the minimum absolute value in the source buffer.
pMinIndx   Pointer to the destination buffer that contains the index of the minimum value in the source buffer.
pNorm   Pointer to the destination buffer that contains the NormC, NormL1, or NormL2 of the values in the source buffer, depending on the function call.
pSrc   Pointer to a source buffer.
pSrc1   Pointer to source buffer one.
pSrc2   Pointer to source buffer two.
pSrcDst   Pointer to a buffer that is both the source and destination.
pSrcIm   Pointer to a source buffer that contains the imaginary component values of an input signal.
pSrcRe   Pointer to a source buffer that contains the real component values of an input signal.
pStdDev   Pointer to the destination buffer that contains the standard deviation of the values in the source buffer.
pSum   Pointer to the destination buffer that contains the sum of all the elements in the source buffer.
ptr   Pointer to a valid memory.
relOp   Constant that indicates which relational operation to perform.
rndMode   Constant that indicates which rounding mode to use when converting from a scalar to an integer.
scaleFactor   Specifies an integer scaling factor for the Sfs operation. The returned result is multiplied by 2^(-scaleFactor).
srcLen   Specifies the number of elements in source buffer
val   Specified value.
valFind   Value of the element to be found.
value   Specified value.
valueGT   Specifies a value to set when a greater-than comparison evaluates as true.
valueLT   Specifies a value to set when a less-than comparison evaluates as true.
vdiv   Specifies the denominator.
vsub   Specifies the subtrahend.
