  • Patent number: 12294708
    Abstract: Techniques for context-adaptive binary arithmetic coding (CABAC) coding with a reduced number of context coded and/or bypass coded bins are provided. Rather than using only truncated unary binarization for the syntax element representing the delta quantization parameter and context coding all of the resulting bins as in the prior art, a different binarization is used and only part of the resulting bins are context coded, thus reducing the worst case number of context coded bins for this syntax element. Further, binarization techniques for the syntax element representing the remaining actual value of a transform coefficient are provided that restrict the maximum codeword length of this syntax element to 32 bits or less, thus reducing the number of bypass coded bins for this syntax element over the prior art.

  • Patent number: 12288069
    Abstract: A streaming engine employed in a digital signal processor specifies a fixed read only data stream. Once fetched the data stream is stored in two head registers for presentation to functional units in the fixed order. Data use by the functional unit is preferably controlled using the input operand fields of the corresponding instruction. A first read only operand coding supplies data from the first head register. A first read/advance operand coding supplies data from the first head register and also advances the stream to the next sequential data elements. Corresponding second read only operand coding and second read/advance operand coding operate similarly with the second head register. A third read only operand coding supplies double width data from both head registers.

  • Patent number: 12289084
    Abstract: Examples of amplifier circuitry regulate a transconductance value (Gm) of operational transconductance amplifiers (OTAs) in the amplifier to be approximately the same, which value is based on a supply voltage and a reference voltage applied to a reference OTA and the internal resistance of the reference OTA. The reference OTA generates an output current based on Gm and the reference voltage, which current is compared to current generated by the supply voltage and internal resistance of the reference OTA. A tail current transistor of each of the reference OTA and a main OTA that mirrors the Gm of the reference OTA provide a tail current feedback path by which Gm is regulated. Amplifying circuitry is coupled to the main OTA to receive current signals. Based on the received current signals, amplifying circuitry generates a differential output voltage signal. The gain of the amplifying circuitry is proportional to the supply voltage and remains relatively constant across process temperature variations.
