Define Documentation

#define _CDF_ACD_PAT_MAP (  _n, _p   )     (((_p) << 4) | _n)

Composes a 16 bit value of a 12 bit pattern and 4 bit length This is used to compress the ACD. Returns: The composed value Parameters: _n  The length of the pattern in bits, must bit < 12 _p  The pattern. The number of significant bits must < 12.

#define _CDF_ACD_PAT_MAP_N (  _m   )     ((_m) & 0xf)

Extracts the length field from the map. Returns: The extracted length field Parameters: _m  The map value

#define _CDF_ACD_PAT_MAP_P (  _m   )     (((_m) >> 4) & 0xfff)

Extracts the right justified pattern from the map. Returns: The right justified pattern Parameters: _m  The map value
