/* The following macros are defined to pack data into 32 bit words.
   mask:    A 32 bit value of N 1 bits starting from lsb where N represents the length of data we are packing.
   start:   Bit start position of data we want.
          ex:  If we want to pack Height(16bits), width(16bits) where width is from (1:16) and height is from (17:32), these are
          the start and mask values for width and height.
          width: start = 0 mask=0xFFFF
          Height:start=  16 mask=0xFFFF
   
   extract: will extract data from x_32 of unsigned integer type from bit start offset(0 to 31) of length based on mask and returns in
            unsigned integer type.
   insert:  Will insert N bits from val_32 ,where N is length based on mask, into x_32 from bit offset based on start. val_32 is expected to
           be a unsigned int of N bits starting with lsb.
