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.

Abstract: Presented herein are system(s), method(s), and apparatus for detecting end of slice groups in a video bitstream. In one embodiment, there is presented a circuit for extracting a data structure from one or more data words. The circuit comprises a multiplexer, a bit pointer, a first logic circuit, and a comparator. The multiplexer provides one or more bits from the one or more data words. The bit pointer points to the bits following the provided one or more bits in the one or more data words. The first logic circuit examines at least portions of the data words for an end of data structure code, the at least portions comprising the one or more bits, and provides an indicator indicating the position of the end of data structure code. The comparator compares the indicator to where the bit pointer points.

Abstract: Presented herein are system(s), method(s), and apparatus for decoding exponential Golomb codes. In one embodiment, there is presented a system for decoding codes having lengths (L) and information bits. The system comprises a circuit and a multiplexer. The circuit provides the information bits of the codes. The multiplexer provides values for the codes, the values for the codes being a function of 2trunc(L/2).
