Abstract
In one embodiment, the invention includes a method for compressing video data using redundant binary mathematics. Other embodiments are described and claimed.
Claims13
A method comprising:
- compressing video data using redundant binary mathematics;
- using redundant binary mathematics and a flip-flop circuit to compute a plurality of speculative sum-of-absolute differences values;
- and
- selecting a sum-of-absolute differences value from the plurality of speculative sum-of-absolute differences values;
- wherein selecting the sum-of-absolute differences value from the plurality of speculative sum-of-absolute differences values includes selecting a first sum-of-absolute differences value but not a second sum-of-absolute differences value, the first and second sum-of-absolute differences values being included in the plurality of speculative sum-of-absolute differences values.

An apparatus comprising:
- logic to compress video data based on redundant binary mathematics;
- a compressor to receive two redundant binary mathematics operands and to compute at least four speculative sum-of-absolute differences values, for the two redundant binary mathematics operands, based on redundant binary mathematics;
- and
- a multistage multiplexor to select a sum-of-absolute differences value from the at least four speculative sum-of-absolute differences values;
- wherein the compressor is to allow no more than three permissible input states of redundant binary numbers.

An apparatus comprising:
- logic to compress video data using redundant binary mathematics;
- a flip-flop circuit to compute a plurality of speculative sum-of-absolute differences values using redundant binary mathematics;
- and
- a multiplexor to select a sum-of-absolute differences value from the plurality of speculative sum-of-absolute differences values;
- wherein the multiplexor is to select the sum-of-absolute differences value from the plurality of speculative sum-of-absolute differences values by performing operations including selecting a first sum-of-absolute differences value but not a second sum-of-absolute differences value, the first and second sum-of-absolute differences values being included in the plurality of speculative sum-of-absolute differences values.
