Parameters
tapsLen
Number of elements in the array containing tap values.
dlyIndex
Current index of the delay line.
pBufferSize
Pointer to the computed buffer size value.
Description
This function computes the size of the external buffer for the FIR LMS filter state structure and stores the result in
pBufferSize
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
 is
NULL
.
ippStsFIRLenErr
Indicates an error when
tapsLen
 is less than, or equal to zero.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
