+ *  This file defines the interface to optimized functions used in erasure
+ *  codes.  Encode and decode of erasures in GF(2^8) are made by calculating the
+ *  dot product of the symbols (bytes in GF(2^8)) across a set of buffers and a
+ *  set of coefficients.  Values for the coefficients are determined by the type
+ *  of erasure code.  Using a general dot product means that any sequence of
+ *  coefficients may be used including erasure codes based on random
+ *  coefficients.
+ *  Multiple versions of dot product are supplied to calculate 1-6 output
+ *  vectors in one pass.
+ *  Base GF multiply and divide functions can be sped up by defining
+ *  GF_LARGE_TABLES at the expense of memory size.

+/**
+ * @file igzip_lib.h
+ *
+ * @brief This file defines the igzip compression and decompression interface, a
+ * high performance deflate compression interface for storage applications.
+ *
+ * Deflate is a widely used compression standard that can be used standalone, it
+ * also forms the basis of gzip and zlib compression formats. Igzip supports the
+ * following flush features:
+ *
+ * - No Flush: The default method where no special flush is performed.
+ *
+ * - Sync flush: whereby isal_deflate() finishes the current deflate block at
+ *   the end of each input buffer. The deflate block is byte aligned by
+ *   appending an empty stored block.
+ *
+ * - Full flush: whereby isal_deflate() finishes and aligns the deflate block as
+ *   in sync flush but also ensures that subsequent block's history does not
+ *   look back beyond this point and new blocks are fully independent.
+ *
+ * Igzip also supports compression levels from ISAL_DEF_MIN_LEVEL to
+ * ISAL_DEF_MAX_LEVEL.
+ *
+ * Igzip contains some behavior configurable at compile time. These
+ * configurable options are:
+ *
+ * - IGZIP_HIST_SIZE - Defines the window size. The default value is 32K (note K
+ *   represents 1024), but 8K is also supported. Powers of 2 which are at most
+ *   32K may also work.
+ *
+ * - LONGER_HUFFTABLES - Defines whether to use a larger hufftables structure
+ *   which may increase performance with smaller IGZIP_HIST_SIZE values. By
+ *   default this option is not defined. This define sets IGZIP_HIST_SIZE to be
+ *   8 if IGZIP_HIST_SIZE > 8K.
+ *
+ *   As an example, to compile gzip with an 8K window size, in a terminal run
+ *   @verbatim gmake D="-D IGZIP_HIST_SIZE=8*1024" @endverbatim on Linux and
+ *   FreeBSD, or with @verbatim nmake -f Makefile.nmake D="-D
+ *   IGZIP_HIST_SIZE=8*1024" @endverbatim on Windows.

+ * Inflate_huff_code data structures are used to store a Huffman code for fast
+ * lookup. It works by performing a lookup in small_code_lookup that hopefully
+ * yields the correct symbol. Otherwise a lookup into long_code_lookup is
+ * performed to find the correct symbol. The details of how this works follows:
+ *
+ * Let i be some index into small_code_lookup and let e be the associated
+ * element.  Bit 15 in e is a flag. If bit 15 is not set, then index i contains
+ * a Huffman code for a symbol which has length at most DECODE_LOOKUP_SIZE. Bits
+ * 0 through 8 are the symbol associated with that code and bits 9 through 12 of
+ * e represent the number of bits in the code. If bit 15 is set, the i
+ * corresponds to the first DECODE_LOOKUP_SIZE bits of a Huffman code which has
+ * length longer than DECODE_LOOKUP_SIZE. In this case, bits 0 through 8
+ * represent an offset into long_code_lookup table and bits 9 through 12
+ * represent the maximum length of a Huffman code starting with the bits in the
+ * index i. The offset into long_code_lookup is for an array associated with all
+ * codes which start with the bits in i.
+ *
+ * The elements of long_code_lookup are in the same format as small_code_lookup,
+ * except bit 15 is never set. Let i be a number made up of DECODE_LOOKUP_SIZE
+ * bits.  Then all Huffman codes which start with DECODE_LOOKUP_SIZE bits are
+ * stored in an array starting at index h in long_code_lookup. This index h is
+ * stored in bits 0 through 9 at index i in small_code_lookup. The index j is an
+ * index of this array if the number of bits contained in j and i is the number
+ * of bits in the longest huff_code starting with the bits of i. The symbol
+ * stored at index j is the symbol whose huffcode can be found in (j <<
+ * DECODE_LOOKUP_SIZE) | i. Note these arrays will be stored sorted in order of
+ * maximum Huffman code length.
+ *
+ * The following are explanations for sizes of the tables:
+ *
+ * Since small_code_lookup is a lookup on DECODE_LOOKUP_SIZE bits, it must have
+ * size 2^DECODE_LOOKUP_SIZE.
+ *
+ * To determine the amount of memory required for long_code_lookup, note that
+ * any element of long_code_lookup corresponds to a code, a duplicate of an
+ * existing code, or a invalid code. Since deflate Huffman are stored such that
+ * the code size and the code value form an increasing function, the number of
+ * duplicates is maximized when all the duplicates are contained in a single
+ * array, thus there are at most 2^(15 - DECODE_LOOKUP_SIZE) -
+ * (DECODE_LOOKUP_SIZE + 1) duplicate elements. Similarly the number of invalid
+ * elements is maximized at 2^(15 - DECODE_LOOKUP_SIZE) - 2^(floor((15 -
+ * DECODE_LOOKUP_SIZE)/2) - 2^(ceil((15 - DECODE_LOOKUP_SIZE)/2) + 1. Thus the
+ * amount of memory required is: NUM_CODES + 2^(16 - DECODE_LOOKUP_SIZE) -
+ * (DECODE_LOOKUP_SIZE + 1) - 2^(floor((15 - DECODE_LOOKUP_SIZE)/2) -
+ * 2^(ceil((15 - DECODE_LOOKUP_SIZE)/2) + 1. The values used below are those
+ * values rounded up to the nearest 16 byte boundary
+ *
+ * Note that DECODE_LOOKUP_SIZE can be any length even though the offset in
+ * small_lookup_code is 9 bits long because the increasing relationship between
+ * code length and code value forces the maximum offset to be less than 288.
