-
- The conversion from a pulse vector to an integer index (encoding) and back
- (decoding) is governed by two related functions, V(N,K) and U(N,K).
-
- V(N,K) = the number of combinations, with replacement, of N items, taken K
- at a time, when a sign bit is added to each item taken at least once (i.e.,
- the number of N-dimensional unit pulse vectors with K pulses).
- One way to compute this is via
- V(N,K) = K>0 ? sum(k=1...K,2**k*choose(N,k)*choose(K-1,k-1)) : 1,
- where choose() is the binomial function.
- A table of values for N<10 and K<10 looks like:
- V[10][10] = {
- {1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
- {1, 2, 2, 2, 2, 2, 2, 2, 2, 2},
- {1, 4, 8, 12, 16, 20, 24, 28, 32, 36},
- {1, 6, 18, 38, 66, 102, 146, 198, 258, 326},
- {1, 8, 32, 88, 192, 360, 608, 952, 1408, 1992},
- {1, 10, 50, 170, 450, 1002, 1970, 3530, 5890, 9290},
- {1, 12, 72, 292, 912, 2364, 5336, 10836, 20256, 35436},
- {1, 14, 98, 462, 1666, 4942, 12642, 28814, 59906, 115598},
- {1, 16, 128, 688, 2816, 9424, 27008, 68464, 157184, 332688},
- {1, 18, 162, 978, 4482, 16722, 53154, 148626, 374274, 864146}
- };
-
- U(N,K) = the number of such combinations wherein N-1 objects are taken at
- most K-1 at a time.
- This is given by
- U(N,K) = sum(k=0...K-1,V(N-1,k))
- = K>0 ? (V(N-1,K-1) + V(N,K-1))/2 : 0.
- The latter expression also makes clear that U(N,K) is half the number of such
- combinations wherein the first object is taken at least once.
- Although it may not be clear from either of these definitions, U(N,K) is the
- natural function to work with when enumerating the pulse vector codebooks,
- not V(N,K).
- U(N,K) is not well-defined for N=0, but with the extension
- U(0,K) = K>0 ? 0 : 1,
- the function becomes symmetric: U(N,K) = U(K,N), with a similar table:
- U[10][10] = {
- {1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
- {0, 1, 1, 1, 1, 1, 1, 1, 1, 1},
- {0, 1, 3, 5, 7, 9, 11, 13, 15, 17},
- {0, 1, 5, 13, 25, 41, 61, 85, 113, 145},
- {0, 1, 7, 25, 63, 129, 231, 377, 575, 833},
- {0, 1, 9, 41, 129, 321, 681, 1289, 2241, 3649},
- {0, 1, 11, 61, 231, 681, 1683, 3653, 7183, 13073},
- {0, 1, 13, 85, 377, 1289, 3653, 8989, 19825, 40081},
- {0, 1, 15, 113, 575, 2241, 7183, 19825, 48639, 108545},
- {0, 1, 17, 145, 833, 3649, 13073, 40081, 108545, 265729}
- };
-
- With this extension, V(N,K) may be written in terms of U(N,K):
- V(N,K) = U(N,K) + U(N,K+1)
- for all N>=0, K>=0.
- Thus U(N,K+1) represents the number of combinations where the first element
- is positive or zero, and U(N,K) represents the number of combinations where
- it is negative.
- With a large enough table of U(N,K) values, we could write O(N) encoding
- and O(min(N*log(K),N+K)) decoding routines, but such a table would be
- prohibitively large for small embedded devices (K may be as large as 32767
- for small N, and N may be as large as 200).
-
- Both functions obey the same recurrence relation:
- V(N,K) = V(N-1,K) + V(N,K-1) + V(N-1,K-1),
- U(N,K) = U(N-1,K) + U(N,K-1) + U(N-1,K-1),
- for all N>0, K>0, with different initial conditions at N=0 or K=0.
- This allows us to construct a row of one of the tables above given the
- previous row or the next row.
- Thus we can derive O(NK) encoding and decoding routines with O(K) memory
- using only addition and subtraction.
-
- When encoding, we build up from the U(2,K) row and work our way forwards.
- When decoding, we need to start at the U(N,K) row and work our way backwards,
- which requires a means of computing U(N,K).
- U(N,K) may be computed from two previous values with the same N:
- U(N,K) = ((2*N-1)*U(N,K-1) - U(N,K-2))/(K-1) + U(N,K-2)
- for all N>1, and since U(N,K) is symmetric, a similar relation holds for two
- previous values with the same K:
- U(N,K>1) = ((2*K-1)*U(N-1,K) - U(N-2,K))/(N-1) + U(N-2,K)
- for all K>1.
- This allows us to construct an arbitrary row of the U(N,K) table by starting
- with the first two values, which are constants.
- This saves roughly 2/3 the work in our O(NK) decoding routine, but costs O(K)
- multiplications.
- Similar relations can be derived for V(N,K), but are not used here.
-
- For N>0 and K>0, U(N,K) and V(N,K) take on the form of an (N-1)-degree
- polynomial for fixed N.
- The first few are
- U(1,K) = 1,
- U(2,K) = 2*K-1,
- U(3,K) = (2*K-2)*K+1,
- U(4,K) = (((4*K-6)*K+8)*K-3)/3,
- U(5,K) = ((((2*K-4)*K+10)*K-8)*K+3)/3,
- and
- V(1,K) = 2,
- V(2,K) = 4*K,
- V(3,K) = 4*K*K+2,
- V(4,K) = 8*(K*K+2)*K/3,
- V(5,K) = ((4*K*K+20)*K*K+6)/3,
- for all K>0.
- This allows us to derive O(N) encoding and O(N*log(K)) decoding routines for
- small N (and indeed decoding is also O(N) for N<3).

-/*A range decoder.
- This is an entropy decoder based upon \cite{Mar79}, which is itself a
- rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.
- It is very similar to arithmetic encoding, except that encoding is done with
- digits in any base, instead of with bits, and so it is faster when using
- larger bases (i.e.: a byte).
- The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$
- is the base, longer than the theoretical optimum, but to my knowledge there
- is no published justification for this claim.
- This only seems true when using near-infinite precision arithmetic so that
- the process is carried out with no rounding errors.
-
- An excellent description of implementation details is available at
- http://www.arturocampos.com/ac_range.html
- A recent work \cite{MNW98} which proposes several changes to arithmetic
- encoding for efficiency actually re-discovers many of the principles
- behind range encoding, and presents a good theoretical analysis of them.
-
- End of stream is handled by writing out the smallest number of bits that
- ensures that the stream will be correctly decoded regardless of the value of
- any subsequent bits.
- ec_tell() can be used to determine how many bits were needed to decode
- all the symbols thus far; other data can be packed in the remaining bits of
- the input buffer.

-** On Intel Pentium processors (especially PIII and probably P4), converting
-** from float to int is very slow. To meet the C specs, the code produced by
-** most C compilers targeting Pentium needs to change the FPU rounding mode
-** before the float to int conversion is performed.
-**
-** Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
-** is this flushing of the pipeline which is so slow.
-**
-** Fortunately the ISO C99 specifications define the functions lrint, lrintf,
-** llrint and llrintf which fix this problem as a side effect.
-**
-** On Unix-like systems, the configure process should have detected the
-** presence of these functions. If they weren't found we have to replace them
-** here with a standard C cast.
