Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
|
|
||||||
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
|
|
||||||
|
|
||||||
Polynomials over GF(2) are represented in binary, one bit per coefficient,
|
|
||||||
with the lowest powers in the most significant bit. Then adding polynomials
|
|
||||||
is just exclusive-or, and multiplying a polynomial by x is a right shift by
|
|
||||||
one. If we call the above polynomial p, and represent a byte as the
|
|
||||||
polynomial q, also with the lowest power in the most significant bit (so the
|
|
||||||
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
|
|
||||||
where a mod b means the remainder after dividing a by b.
|
|
||||||
|
|
||||||
This calculation is done using the shift-register method of multiplying and
|
|
||||||
taking the remainder. The register is initialized to zero, and for each
|
|
||||||
incoming bit, x^32 is added mod p to the register if the bit is a one (where
|
|
||||||
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
|
|
||||||
x (which is shifting right by one and adding x^32 mod p if the bit shifted
|
|
||||||
out is a one). We start with the highest power (least significant bit) of
|
|
||||||
q and repeat for all eight bits of q.
|
|
||||||
|
|
||||||
The first table is simply the CRC of all possible eight bit values. This is
|
|
||||||
all the information needed to generate CRCs on data a byte at a time for all
|
|
||||||
combinations of CRC register values and incoming bytes. The remaining tables
|
|
||||||
allow for word-at-a-time CRC calculation for both big-endian and little-
|
|
||||||
endian machines, where a word is four bytes.

/*

Decode literal, length, and distance codes and write out the resulting
|
|
||||||
literal and match bytes until either not enough input or output is
|
|
||||||
available, an end-of-block is encountered, or a data error is encountered.
|
|
||||||
When large enough input and output buffers are supplied to inflate(), for
|
|
||||||
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
|
||||||
inflate execution time is spent in this routine.
|
|
||||||
|
|
||||||
Entry assumptions:
|
|
||||||
|
|
||||||
state->mode == LEN
|
|
||||||
strm->avail_in >= 6
|
|
||||||
strm->avail_out >= 258
|
|
||||||
start >= strm->avail_out
|
|
||||||
state->bits < 8
|
|
||||||
|
|
||||||
On return, state->mode is one of:
|
|
||||||
|
|
||||||
LEN -- ran out of enough output space or enough available input
|
|
||||||
TYPE -- reached end of block code, inflate() to interpret next block
|
|
||||||
BAD -- error in block data
|
|
||||||
|
|
||||||
Notes:
|
|
||||||
|
|
||||||
- The maximum input bits used by a length/distance pair is 15 bits for the
|
|
||||||
length code, 5 bits for the length extra, 15 bits for the distance code,
|
|
||||||
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
|
||||||
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
|
||||||
checking for available input while decoding.
|
|
||||||
|
|
||||||
- The maximum bytes that a single length/distance pair can output is 258
|
|
||||||
bytes, which is the maximum length that can be coded. inflate_fast()

|
|

Process a set of code lengths to create a canonical Huffman code. The
|
|
||||||
code lengths are lens[0..codes-1]. Each length corresponds to the
|
|
||||||
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
|
||||||
symbols by length from short to long, and retaining the symbol order
|
|
||||||
for codes with equal lengths. Then the code starts with all zero bits
|
|
||||||
for the first code of the shortest length, and the codes are integer
|
|
||||||
increments for the same length, and zeros are appended as the length
|
|
||||||
increases. For the deflate format, these bits are stored backwards
|
|
||||||
from their more natural integer increment ordering, and so when the
|
|
||||||
decoding tables are built in the large loop below, the integer codes
|
|
||||||
are incremented backwards.
|
|
||||||
|
|
||||||
This routine assumes, but does not check, that all of the entries in
|
|
||||||
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
|
||||||
1..MAXBITS is interpreted as that code length. zero means that that
|
|
||||||
symbol does not occur in this code.
|
|
||||||
|
|
||||||
The codes are sorted by computing a count of codes for each length,
|
|
||||||
creating from that a table of starting indices for each length in the
|
|
||||||
sorted table, and then entering the symbols in order in the sorted
|
|
||||||
table. The sorted table is work[], with that space being provided by
|
|
||||||
the caller.
|
|
||||||
|
|
||||||
The length counts are used for other purposes as well, i.e. finding
|
|
||||||
the minimum and maximum length codes, determining if there are any
|
|
||||||
codes at all, checking for a valid set of lengths, and looking ahead
|
|
||||||
at length counts to determine sub-table sizes when building the
|
|
||||||
decoding tables.

Create and fill in decoding tables. In this loop, the table being
|
|
||||||
filled is at next and has curr index bits. The code being used is huff
|
|
||||||
with length len. That code is converted to an index by dropping drop
|
|
||||||
bits off of the bottom. For codes where len is less than drop + curr,
|
|
||||||
those top drop + curr - len bits are incremented through all values to
|
|
||||||
fill the table with replicated entries.
|
|
||||||
|
|
||||||
root is the number of index bits for the root table. When len exceeds
|
|
||||||
root, sub-tables are created pointed to by the root entry with an index
|
|
||||||
of the low root bits of huff. This is saved in low to check for when a
|
|
||||||
new sub-table should be started. drop is zero when the root table is
|
|
||||||
being filled, and drop is root when sub-tables are being filled.
|
|
||||||
|
|
||||||
When a new sub-table is needed, it is necessary to look ahead in the
|
|
||||||
code lengths to determine what size sub-table is needed. The length
|
|
||||||
counts are used for this, and so count[] is decremented as codes are
|
|
||||||
entered in the tables.
|
|
||||||
|
|
||||||
used keeps track of how many table entries have been allocated from the
|
|
||||||
provided *table space. It is checked when a LENS table is being made
|
|
||||||
against the space in *table, ENOUGH, minus the maximum space needed by
|
|
||||||
the worst case distance code, MAXD. This should never happen, but the
|
|
||||||
sufficiency of ENOUGH has not been proven exhaustively, hence the check.
|
|
||||||
This assumes that when type == LENS, bits == 9.
|
|
||||||
|
|
||||||
sym increments through all symbols, and the loop terminates when
|
|
||||||
all codes of length max, i.e. all codes, have been processed. This
|
|
||||||
routine permits incomplete codes, so another loop after this one fills
|
|
||||||
in the rest of the decoding tables with invalid code markers.
