+

+
+
+                            RSPC resp. P- and Q-Parity
+
+   ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
+   Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
+   polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
+   Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
+   as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
+   and a MSB matrix of the same layout. Parity bytes are to be computed
+   from these 8-bit values.
+   2 P-bytes cover each column of 24 bytes. They get appended to the matrix
+   as rows 24 and 25.
+   2 Q-bytes cover each the 26 diagonals of the extended matrix.
+
+   Both parity byte pairs have to be computed so that extended rows or
+   diagonals match this linear equation:
+      H x V = (0,0)
+   H is a 2-row matrix of size n matching the length of the V ectors
+     [   1        1     ...   1   1 ]
+     [ x^(n-1)  x^(n-2)      x^1  1 ]
+   Vp represents a P-row. It is a byte vector consisting of row bytes at
+   position 0 to 23 and the two parity bytes which shall be determined
+   at position 24 and 25. So Hp has 26 columns.
+   Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
+   bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
+   So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
+
+   By applying some high school algebra one gets the parity bytes b0, b1 of
+   vector V = (n_payload_bytes, b0 , b1) as
+
+     b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
+          / (H[n+1] - H[n])
+     b1 = - SUM(n_payload_bytes) - b0
+
+   H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
+   The result has to be computed by Galois field arithmetics. See below.
+
+   The P-parity bytes of each column get reunited as LSB and MSB of two words.
+   word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
+   The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
+   to 1143, word0 to 1144 to 1169.
+   >>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
+   >>> But the new output matches the old output only if it is done that way.
+   >>> See correctness reservation below.
+
+   Algebra on Galois fields is the same as on Rational Numbers.
+   But arithmetics is defined by operations on polynomials rather than the
+   usual integer arithmetics on binary numbers.
+   Addition and subtraction are identical with the binary exor operator.
+   Multiplication and division would demand polynomial division, e.g. by the
+   euclidian algorithm. The computing path over logarithms and powers follows
+   algebra and allows to reduce the arithmetic task to table lookups, additions
+   modulo 255, and exor operations. Note that the logarithms are natural
+   numbers, not polynomials. They get added or subtracted by the usual addition
+   (not by exor) and their polynomial power depends on their value modulo 255.
+
+   Needed are a logarithm table and a power table (or inverse logarithm table)
+   for Galois Field GF(2^8) which will serve to perform the peculiar
+   multiplication and division operation of Galois fields.
+
+   The power table is simply an enumeration of x^n accorting to
+   GF-multiplication. It also serves as second line of matrix H for the parity
+   equations:
+     Hp[i] = gfpow[25-i] , i out of {0,..,25}
+     Hq[i] = gfpow[44-i] , i out of {0,..,44}
+
+   The logarithm table is the inverse permutation of the power table.
+
+   Some simplifications apply to the implementation:
+   In the world of Galois fields there is no difference between - and +.
+   The term (H[n+1] - H[n]) is constant: 3.
+
+   -------------------------------------------------------------------------
+
+
+                                 Scrambling
+
+   ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
+   with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
+   a 15-bit register.
+   It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
+ 
+   Comparing this with explanations in 
+     http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
+   one can recognize the diagram as a Fibonacci Implementation. But there seems
+   really to be one bit box too many.
+
+   The difference of both lengths is expressed in function next_bit() by
+   the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
+   Comparing the output of both alternatives with the old scrambler output
+   lets 15 bit win for now.
+
+   So the prescription is to start with 15 bit value 1, to use the lowest bit
+   as output, to shift the bits down by one, to exor the output bit with the
+   next lowest bit, and to put that exor result into bit 14 of the register.
+
+   -------------------------------------------------------------------------
+
+
+                             Correctness Reservation
+
+   In both cases, parity and scrambling, the goal for now is to replicate the
+   output of the dismissed old lec.c by output which is based on published
+   specs and own implementation code. Whether they comply to ECMA-130 is a
+   different question which can only be answered by real test cases for
+   raw CD recording.
+
+   Of course this implementation will be corrected so that it really complies
+   to ECMA-130 as soon as evidence emerges that it does not yet.

+
+   Simplified data transmission for DVD. libburn via Linux USB is 30 % slower
+   than growisofs or cdrecord when transmitting 32 KB chunks.
+   With 64 KB chunks it is 20% faster than the competitors.
+   No heavy CPU load is visible but there might be subtle race conditions in
+   the USB driver which work better with shorter time gaps between WRITE
+   commands.
+
+   Insight: It is actually about the interference of track source reading
+            with SCSI writing via USB. growisofs reads with O_DIRECT into a
+            mmap()ed buffer. When doing the same, libburn with 32 KB chunks
+            reaches similar write speed.
+            On the other hand, 64 KB chunks are 20% faster than that and
+            are not improved by reading O_DIRECT.
+
+            O_DIRECT is a property of the input fd of struct burn_source.
+            It can only be done with properly aligned memory and with aligned
+            read size. Alignment size is file system system specific.
+            System call
+                mmap(NULL, (size_t) buffer_size, PROT_READ | PROT_WRITE,
+                     MAP_SHARED | MAP_ANONYMOUS, -1, (off_t) 0);
+            is supposed to allocate a properly aligned buffer.
+            64 KB is supposed to be a safe size.
+            Actually mmap() seems to be the main cause for a positive effect
+            of O_DIRECT.
+
+   This simplified transmission function did not bring visible benefit.
+   So for now it is not worth to teach it all applicable details of old
+   CD sector oriented transmission.
