Low-cost hash table construction and hash-based block matching for variable-size blocks
Innovations in hash table construction and hash-based block matching for image encoding or video encoding are described. For example, an encoder determines hash values for base-size candidate blocks in a reference picture. The encoder stores, in a hash table, the hash values for the base-size candidate blocks. The encoder encodes a trial-size current block in a current picture. In some cases, the trial-size current block has a block size larger than the base block size. As part of the encoding, the encoder uses hash-based block matching, between base-size current blocks of the trial-size current block and the base-size candidate blocks, to identify a trial-size matching block, if any, in the reference picture. The encoder stores hash values only for the base-size candidate blocks. This can significantly reduce the computational cost and memory cost for hash table construction during encoding, without hurting compression efficiency or the overall speed of encoding. |

Packed ingress interface for network apparatuses
Multiple ports of a network device are muxed together to form a single packed ingress interface into a buffer. A multiplexor alternates between the ports in alternating input clock cycles. Extra logic and wiring to provide a separate writer for each port is avoided, since the packed interface and buffer writers operate at higher speeds and/or have more bandwidth than the ports, and are thus able to handle incoming data for all of the ports coupled to the packed ingress interface. A packed ingress interface may also or instead support receiving data for multiple data units (e.g. multiple packets) from a single port in a single clock cycle, thereby reducing the potential to waste bandwidth at the end of data units. The interface may send the ending segments of the first data unit to the buffer. However, the interface may hold back the starting segments of the second data unit in a cache. In an embodiment, a gear shift merges the first part of each subsequent portion of the second data unit with the cached data to form a full-sized data unit portion to send downstream, while the second part of the portion replaces the cached data. When the end of the second data unit is detected, if any segments of the second data unit remain after the merger process, the remainder is sent downstream as a separate portion at the same time. |

Dynamically assigning multi-modality circumstantial data to assistant action requests for correlating with subsequent requests
Implementations set forth herein relate to an automated assistant that uses circumstantial condition data, generated based on circumstantial conditions of an input, to determine whether the input should affect an action been initialized by a particular user. The automated assistant can allow each user to manipulate their respective ongoing action without necessitating interruptions for soliciting explicit user authentication. For example, when an individual in a group of persons interacts with the automated assistant to initialize or affect a particular ongoing action, the automated assistant can generate data that correlates that individual to the particular ongoing action. The data can be generated using a variety of different input modalities, which can be dynamically selected based on changing circumstances of the individual. Therefore, different sets of input modalities can be processed each time a user provides an input for modifying an ongoing action and/or initializing another action. |

Distinguishing voice commands
Aspects of the present disclosure relate to distinguishing voice commands.
