Methods, systems, and apparatus, including a managed device comprising memory storage, one or more control registers, and circuitry to perform operations of receiving, from a control system, one or more posted write operations directed to the one or more control registers; based on the one or more posted write operations, storing in the one or more control registers, data specifying at least a system address of a memory of the control system, where the system address corresponds to a starting address of a predetermined section of the memory; and transferring managed device data from the memory storage to the predetermined section of the memory of the control system by issuing, to the control system and based on the system address of the memory, one or more posted write operations to write the managed device data to the predetermined section of the memory.

Posted operation data control

This disclosure relates to compressing and/or decompressing a group of similar data units, such as a table or queue of data units processed by a networking device or other computing apparatus. Each data unit in the group may only have values for fields in a master set. The described systems are particularly suited for hardware-level processing of groups of sparsely-populated data units, in which a large number of the data units have values for only a small number of the fields. In an embodiment, non-value carrying fields in a data unit are compressed based on a compression profile selected for the data unit. The compression profile indicates, for each master field, whether the compressed data unit includes a value for that field. Non-value carrying fields are omitted from the compressed data unit. The compression profile also permits compression of value-carrying fields using variable-width field lengths specified in the profile.
