Abstract
Presented herein are system(s), method(s), and apparatus for converting unsigned fixed length codes to signed fixed length codes. In one embodiment, there is presented a circuit for converting an unsigned code to a signed code. The circuit comprises a multiplexer. The multiplexer comprises a first input, a second input, and an output. The first input receives a first value, the first value being the right shifted unsigned code plus one. The second input receives a second value, the second value being an inverse of a right shifted unsigned code plus one. The output outputs a selected one of the first value received by the first input or the second value received by the second input. The multiplexer selects the selected one of the first value or the second value based on a least significant bit of the unsigned code.
