Original commit message from CVS: Remove GPL'ed mmx32idct.c code and supporting code, since logic in gst-plugins is not supposed to be GPL'ed. This code provided MMX optimisations, but was never compiled in since configure never set HAVE_LIBMMX anyway.

/* MPEG2AVI
*/
|
||||
/* --------
*/
|
||||
/* v0.16B33 initial release
*/
|
||||
/*
*/
|
||||
/* This was one of the harder pieces of work to code.
*/
|
||||
/* Intel's app-note focuses on the numerical issues of the algorithm, but
*/
|
||||
/* assumes the programmer is familiar with IDCT mathematics, leaving the
*/
|
||||
/* form of the complete function up to the programmer's imagination.
*/
|
||||
/*
*/
|
||||
/* ALGORITHM OVERVIEW
*/
|
||||
/* ------------------
*/
|
||||
/* I played around with the code for quite a few hours. I came up
*/
|
||||
/* with *A* working IDCT algorithm, however I'm not sure whether my routine
*/
|
||||
/* is "the correct one." But rest assured, my code passes all six IEEE
*/
|
||||
/* accuracy tests with plenty of margin.
*/
|
||||
/*
*/
|
||||
/* My IDCT algorithm consists of 4 steps:
*/
|
||||
/*
*/
|
||||
/* 1) IDCT-row transformation (using the IDCT-row function) on all 8 rows
*/
|
||||
/* This yields an intermediate 8x8 matrix.
*/
|
||||
/*
*/
|
||||
/* 2) intermediate matrix transpose (mandatory)
*/
|
||||
/*
*/
|
||||
/* 3) IDCT-row transformation (2nd time) on all 8 rows of the intermediate
*/
|
||||
/* matrix. The output is the final-result, in transposed form.
*/
|
||||
/*
*/
|
||||
/* 4) post-transformation matrix transpose
*/
|
||||
/* (not necessary if the input-data is already transposed, this could
*/
|
||||
/* be done during the MPEG "zig-zag" scan, but since my algorithm
*/
|
||||
/* requires at least one transpose operation, why not re-use the
*/
|
||||
/* transpose-code.)
*/
|
||||
/*
*/
|
||||
/* Although the (1st) and (3rd) steps use the SAME row-transform operation,
*/
|
||||
/* the (3rd) step uses different shift&round constants (explained later.)
*/
|
||||
/*
*/
|
||||
/* Also note that the intermediate transpose (2) would not be neccessary,
*/
|
||||
/* if the subsequent operation were an iDCT-column transformation. Since
*/
|
||||
/* we only have the iDCT-row transform, we transpose the intermediate
*/
|
||||
/* matrix and use the iDCT-row transform a 2nd time.
*/
|
||||
/*
*/
|
||||
/* I had to change some constants/variables for my method to work :
*/
|
||||
/*
*/
|
||||
/* As given by Intel, the #defines for SHIFT_INV_COL and RND_INV_COL are
*/
|
||||
/* wrong. Not surprising since I'm not using a true column-transform
*/
|
||||
/* operation, but the row-transform operation (as mentioned earlier.)
*/
|
||||
/* round_inv_col[], which is given as "4 short" values, should have the
*/
|
||||
/* same dimensions as round_inv_row[]. The corrected variables are
*/
|
||||
/* shown.
*/
|
||||
/*
*/
|
||||
/* Intel's code defines a different table for each each row operation.
*/
|
||||
/* The tables given are 0/4, 1/7, 2/6, and 5/3. My code only uses row#0.
*/
|
||||
/* Using the other rows messes up the overall transform.
*/
|
||||
/*
*/
|
||||
/* IMPLEMENTATION DETAILs
*/
|
||||
/* ----------------------
*/
|
||||
/*
*/
|
||||
/* I divided the algorithm's work into two subroutines,
*/
|
||||
/* 1) idct_mmx32_rows() - transforms 8 rows, then transpose
*/
|
||||
/* 2) idct_mmx32_cols() - transforms 8 rows, then transpose
*/
|
||||
/* yields final result ("drop-in" direct replacement for INT32 IDCT)
*/
|
||||
/*
*/
|
||||
/* The 2nd function is a clone of the 1st, with changes made only to the
*/
|
||||
/* shift&rounding instructions.
*/
|
||||
/*
*/
|
||||
/* In the 1st function (rows), the shift & round instructions use
*/
|
||||
/* SHIFT_INV_ROW & round_inv_row[] (renamed to r_inv_row[])
*/
|
||||
/*
*/
|
||||
/* In the 2nd function (cols)-> r_inv_col[], and
*/
|
||||
/* SHIFT_INV_COL & round_inv_col[] (renamed to r_inv_col[])
*/
|
||||
/*
*/
|
||||
/* Each function contains an integrated transpose-operator, which comes
*/
|
||||
/* AFTER the primary transformation operation. In the future, I'll optimize
*/
|
||||
/* the code to do more of the transpose-work "in-place". Right now, I've
*/
|
||||
/* left the code as two subroutines and a main calling function, so other
*/
|
||||
/* people can read the code more easily.
