RS Decoder Functions

The table below lists the Intel IPP RS decoder functions.

Intel IPP RS Decoder Functions
Function Base Name	Operation
RSDecodeGetSize	Gets the size of the ippsRSDecodeSpec_8u context.
RSDecodeInit	Initializes user-supplied memory as the IppsRSDecodeSpec_8u context for future use.
RSDecodeBMGetBufferSize	Gets the size of a work buffer for the decoding operation that uses the Berlekamp-Massey (BM) decoding algorithm.
RSDecodeEEGetBufferSize	Gets the size of a work buffer for the decoding operation that uses the Extended Euclidean (EE) decoding algorithm.
RSDecodeBM	Performs the RS decoding operation that uses the BM decoding algorithm.
RSDecodeEE	Performs the RS decoding operation that uses the EE decoding algorithm.

The functions described in this section use the RS(n,k) decoder context having the IppsRSDecodeSpec_8u type, which, in addition to the lengths n and k, carries the definition of the finite field to be used for decoding and roots of the RS-generating polynomial.
