-////////// AVC ILDB Chroma Core /////////////////////////////////////////////////////////////////////////////////
-//
-// This core performs AVC U or V ILDB filtering on one horizontal edge (8 pixels) of a MB.
-// If data is transposed, it can also de-block a vertical edge.
-//
-// Bafore calling this subroutine, caller needs to set the following parameters.
-//
-// - EdgeCntlMap1 // Edge control map A
-// - EdgeCntlMap2 // Edge control map B
-// - P_AddrReg // Src and dest address register for P pixels
-// - Q_AddrReg // Src and dest address register for Q pixels
-// - alpha // alpha corresponding to the edge to be filtered
-// - beta // beta corresponding to the edge to be filtered
-// - tc0 // tc0 corresponding to the edge to be filtered
-//
-// U or V:
-// +----+----+----+----+
-// | P1 | p0 | q0 | q1 |
-// +----+----+----+----+
-//
-// p1 = r[P_AddrReg, 0]<16;8,2>
-// p0 = r[P_AddrReg, 16]<16;8,2>
-// q0 = r[Q_AddrReg, 0]<16;8,2>
-// q1 = r[Q_AddrReg, 16]<16;8,2>
