A device and a method for managing power consumption of a plurality of data processing units. A scheduler () schedules a first process step for a first data processing unit () consuming a high power within a first deadline and a second process step for a second data processing unit () also consuming a high power within a second deadline. The scheduler further schedules the first process step and the second process step such that the two process steps do not occur concurrently thereby reducing the peak power draw from a power supply while preserving deadlines. This is particularly beneficial in battery-operated equipment, such as portable electronic multimedia devices, since peak power drain has been found to be an important factor in determining the battery capacity.

Device and a method for managing power consumption of a plurality of data processing units

Method of processing data of at lease one data stream, data processing module for processing at a of at least one data stream, data processing system comprising such module, computer program product, data storage system and method of use thereof. For a time-based transfer of data to or from a device, data streams may be given a system ID and it is proposed to dynamically distribute available stream IDs. The proposed concept provides for indicating a type of data stream, providing and/or handling a set of stream IDs comprising a number of stream IDs and issuing a stream ID from the set of stream IDs to the data stream depending on the type of data stream. In a preferred embodiment, it is proposed to reserve one stream ID for an audio-video request, characterized by having no error handling time available. A further stream ID may be reserved for best effort requests. Still further streams IDs may not be reserved but are freely available for pending error handling procedures, such as time-sliced error handling procedures.

Method of processing and prioritizing at least one logical data stream for transmission over at least one physical data stream

The present invention relates to a method, a content status information providing unit (), a portable electronic device (), a computer program product () and a computer program element for providing status information related to at least one data content file, within a portable electronic device (), to a user, the method comprising the steps of obtaining a battery capacity value (step), obtaining content related information for at least one data content file (steps), determining a content status of the' at least one data content file, in dependence of the obtained battery capacity related to the at least one data content file (steps), and providing information on the determined content status to the user (step), such that the user of the portable electronic device () can be made aware of the status of the at least one data content file.

Content status provision related to volatile memories

The present invention relates to reduction of power consumption of electronic mass storage devices, and more particularly to such a reduction of power consumption in mobile infotainment products. These devices are equipped with a subsystem comprising a mass storage device () and a buffer memory (). The size of the buffer memory () is adapted in such a way that optimally low power consumption is achieved. This accomplishment by activating or deactivating memory banks () comprised in the buffer memory chips. The amount of memory banks () activated is determined by operating characteristics of the subsystem, e.g. a desired bit-rate to be achieved for transmissions to/from the mass storage device ().

Power saving method and system

Real-time audio video applications require guaranteed request service times from a hard disc drive. This requirement is not always fulfilled due to some unexpected delays in service times. Re-allocated sectors are one of the causes of such delays. A scheme for conversion of re-maps into slips in a hard disc drive is suggested. Converting re-allocated sectors into slipped or skipped sectors can prevent such a delay, since slipped sectors cause much less or even negligible performance loss than re-allocated sectors.

Data storage apparatus and method for handling data on a data storage apparatus

The invention relates to a method of writing data to and reading data from a memory () by a host. By limiting processing time, time restrictions regarding the data to be processed can be met. However, this is at the expense of data integrity. By setting time limits for a group () of multiple processing assignments and dynamic allocation of time, reserved for error recovery and retries, data integrity can be improved, while time limits can still be met. Furthermore, by attaching priorities to the assignments, multiple types of data can be handled in one group of assignments. For example, assignments with real-time requirements can be put in a group with assignments with best effort requirements. In this way, more flexible planning of processing assignments is possible. The invention also relates to a system for writing data to and reading data from a memory.
