System (s), method (s), and apparatus for converting unsigned fixed length codes (decoded from exponential golomb codes) to signed fixed length codes

A circuit for converting an unsigned code to a signed code, said circuit comprising:

• a multiplexer comprising:
• a first input operable to receive a first value, the first value being a right shifted unsigned code plus one;
• a second input operable to receive a second value, the second value being an inverse of a right shifted unsigned code plus one;
• and
• an output operable to output a selected one of the first value received by the first input or the second value received by the second input;
• and
• wherein said multiplexer is operable to select the selected one of the first value or the second value based on a least significant bit of the unsigned code.

A method for converting an unsigned code to a signed code, said method comprising:

• receiving a right-shifted unsigned code plus one;
• receiving an inverted right-shifted unsigned code plus one;
• and
• selecting one of the right-shifted unsigned code plus one or the inverted right-shifted unsigned code plus one, based on a least significant bit of the unsigned code.
