A method and system for power management is provided. To control power supplied to a second electronic device (), an electronic system () comprises a power management subsystem (), a first electronic device (); The power management subsystem () monitors the power consumed by the first electronic device () to control the power supplied to the second electronic device (). A method for power management of a second electronic device () is provided. A power management subsystem () is provided.

Method and system for power management

A power manager () and method for managing the power supplied to an electronic device is provided. Furthermore, a system wherein the power supplied to an electronic device is managed is provided. The power manager () is operative to monitor a hardware monitor () during a monitoring time period. The hardware monitor () is coupled to an electronic device (). The electronic device () has a workload during operational use. The hardware monitor is operative to indicate the workload of the electronic device (). The power manager is operative to control power supplied to the electronic device () in dependency on the monitoring.

Power manager and method for managing power

The present invention discloses an integrated circuit arrangement () comprising a data communication network comprising a plurality of connections (), a plurality of modules () coupled to the data communication network via at least one network interface (), the network interface comprising a plurality of buffers; a remote service module () being coupled to the data communication network via a further network interface (), wherein each of said modules () is arranged to provide its network interface () with a service request () for the remote service module (), said network interface being arranged to extend said service request with a first identifier () for establishing a network connection () with a remote service module (); and a circuit portion () comprising a plurality of buffers () between the at least one network interface () and the remote service module () for storing service requests () from the plurality of modules (), said circuit portion comprising decoding logic () for selecting one of said buffers () by decoding a further identifier () embedded in the service request ().

Integrated circuit arrangement for buffering service requests

A resource controller that includes a first buffer configured to store requests of a first predefined category having a first priority. In addition, the resource controller includes at least a second buffer configured to store requests of a second predefined category having a second priority where the first priority is set such that processing requests of the first category has priority over processing the requests of the second category. Also, the resource controller includes a mechanism configured to block the requests of the first category when a predefined condition is met.

Systems and methods for resource controlling

The present application relates to a method for resource controlling comprising controlling the processing of requests of a first category having a first priority. The method comprises controlling the processing of requests of a second category having a second priority, wherein the first priority is set such that processing the requests of the first category has priority over processing the requests of the second category. The method comprises blocking requests of the first category by a mechanism that detects when a predefined condition regarding the service provided to the second category is met.

Resource controlling with dynamic priority adjustment

Disclosed is a method of switching modes in a serial data communication network comprising a plurality of interconnected nodes, each of said nodes comprising a plurality of mode-dependent configurations, the method including, during a first mode, issuing an instruction to said nodes, said instruction identifying a next mode of the data communication network; terminating said first mode; and following said termination, reconfiguring each of said nodes in accordance with the configuration corresponding to said next mode identified by said instruction. A serial data communication network implementing such a method is also disclosed.

Network mode switching method and serial data communication network

Requests from a plurality of different agents () are passed to a request handler via a request concentrator. In front of the request concentrator the requests are queued in a plurality of queues (). A first one of the agents is configured to issue a priority changing command with a defined position relative to pending requests issued by the first one of the agents () to the first one of the queues (). An arbiter (), makes successive selections selecting queues () from which the request concentrator () will pass requests to the request handler (), based on relative priorities assigned to the queues (). The arbiter () responds to the priority changing command by changing the priority of the first one of the queues (), selectively for a duration while the pending requests up to the defined position are in the first one of the queues (). Different queues may be provided for read and write requests from the first one of the agents. In this case, the priority raising request from the agent may be used to raise the priority level of the write queue temporarily to the level of the read queue, until all write requests issued before the priority raising command from the agent have been passed to the request handler.

Data processing circuit with arbitration between a plurality of queues

When distributing a setof frameseach with encoded datafrom a transmitterto a receiver, a dependent framerequires an independent framefor decoding, and the transmittingof the framesfrom a bufferat the transmitteris reordered such that the dependent frameis sent after the independent frame. In particular, a transmission policy wherein bufferinga further frametakes into account both: if the further framerequires zero, one or two framesof the setfor decoding, and the current framesbuffered at the first and the second positionof the transmit buffer

A method of determining a best-case response time of a first periodic task, the method comprising a first step based upon Rate Monotonic Analysis of determining the priorities of the tasks that have to be scheduled on a system. In order to determine whether the set of tasks can be scheduled on the system, the best-vase response time in addition to the worst-case response time is determined per task. This best-case response time is substantially equal to the difference between the start of a task with a lower priority and the completion of this low priority task, the start being right after the release of the low priority task and the completion coinciding with the simultaneous release all higher priority tasks.

Method of and system for determining a best-case response time of a periodic task

In consumer devices, like digital television sets or set-top boxes, there can be a problem with a sudden load increase caused by for example a scene change and user focus. During such a load increase, the quality of service of the application having the user focus will decrease until the device detects the load increase. The device can reallocate resources to the application having the user focus after which the quality of service will increase again towards its previous level. However, the user may have noticed the quality decrease. In order to prevent this noticeable decrease of quality in overload situations, a method and a system are provided that guarantees a worst-case budget to the application having user focus and conditionally guarantees a budget surplus to an application not having the user focus. The latter application can then use that budget surplus to operate at a higher quality of service level.
