  • High performance context-adaptive video processor
    Patent number: 8391367
    Abstract: An apparatus comprising a transform circuit, a first coder circuit, a second coder circuit, and a memory circuit. The transform circuit may be configured to generate (i) one or more first coefficients in response to a sample signal when in a first mode and (ii) the sample signal in response to the first coefficients when in a second mode. The first coder circuit may be configured to generate (i) a first bitstream signal in response to one or more second coefficients when in the first mode and (ii) the second coefficients in response to the first bitstream signal when in the second mode. The second coder circuit may be configured to generate (i) a second bitstream signal in response to one or more third coefficients when in the first mode and (ii) the third coefficients in response to the second bitstream signal when in the second mode. The memory circuit may be configured to store the first coefficients, the second coefficients, and the third coefficients.
