Patent Disclosure: Transitioning Digital Data Processors for Power Efficiency

Strategic Insights -

A patent titled "TRANSITIONING DIGITAL DATA PROCESSORS BETWEEN POWER SAVINGS AND NON-POWER SAVINGS MODES" has been published on June 23 by the World Intellectual Property Organization. The patent, attributed to Analog Devices, Inc. with inventors from various countries, presents an innovative approach to processing multimedia digital data in a power-efficient manner. The invention involves a sink with a switchable selector and multiple decryption engines to synchronize with corresponding encryption engines of a data source. The sink can operate in both power-saving and non-power-saving modes, with additional circuitry enabling the transition between the two.

Key Takeaways:

  • The patent applies to a sink that can process multimedia digital data and switch between power-saving and non-power-saving modes.
  • The sink features a switchable selector to couple to an output port and multiple decryption engines to synchronize with corresponding encryption engines.
  • The invention requires a control circuit to detect encrypted data in input ports and synchronize decryption engines with corresponding encryption engines.
  • The patent describes additional circuitry for operating the sink in a power-saving mode, reducing energy consumption.
  • The techniques described can be applied to a variety of digital data processing applications, including multimedia streaming and data transfer over HDMI.
