System-on-chip (SoC) designs include large amounts of interconnected intellectual property blocks and standard-cell logic using complex bus fabrics. Today SoC design-closure that validates design targets of area, timing, congestion and power constraints is accomplished post routing as over 80% of validation problems are due to global-interconnect.

Power economizing by powering down hub partitions
An approach to power economization in a spoke and hub environment is presented. When a hub receives a data set from a first spoke, the hub writes the data set to a first partition that is associated with the first spoke. After the data transfer is complete, the hub powers down the first partition. If the first spoke sends additional data transfers to the hub while the first partition is powered down, the hub stores the additional data transfers in a second partition. When the first partition is powered up again, the hub moves the data intended for the first partition and that was stored in the second partition. The data is moved from the second partition to the first partition. The hub may monitor the size of the addition data transfers. If the data transfer is large, the hub may power up the first partition, write the data in the first partition, and move to the first partition any data that was intended for the first partition but written to the second partition while the first partition was powered down. |

Multi-part aggregated variable in structured external storage
A mechanism is provided for multi-part aggregated variables in structured external storage. The shared external storage provides a serialized, aggregated structure update capability. The shared external storage identifies each local value for which a group value is needed by name. Each time a member writes out its value, the member specifies the name of the object, the member's current value, and the type of aggregate function to apply (e.g., minimum, maximum, etc.). The structured external storage in one atomic operation updates the member's value, recalculates the aggregate of all of the individual values, and returns the aggregate to the member. The advantage of this approach is that it requires only one write operation to the structured external storage. The update operation does not require locking, because the operation is atomic. |

Application layer communication via single radio block access
Embodiments herein advantageously reduce the amount of control signalling and header information that must accompany an application layer message when transporting that message from a wireless device to a supporting application server via an intermediate node.
