The present invention provides an electronic network with a plurality of processing units that are arranged in sub-networks in a hierarchical and heterogeneous way. The network features a data stream controller that is coupled to any one of the sub-networks and that is adapted to transmit data to any one of the sub-networks. Further, the network has a data transmission port that is coupled to the data stream controller and that provides a high-speed data transmission to the data stream controller. The data stream controller serves to concurrently provide data and in particular flashing data to the various control units in a way that is adapted to the communication protocol and the data transfer rate of each sub-network. The invention therefore provides fast and autonomous flashing of a plurality of processing units, such as electronic control units in a network embedded system such as commonly used in the framework of automotive electronic networks. The data stream controller and its coupling to the various sub-networks provides a non-hierarchical and direct access to any sub-network and/or control unit of a heterogeneous and hierarchical network.

A computer server system comprises multiple computer server units, each computer server comprising a server processing system. Each computer server comprises a local subsystem access module which is standardized for the multiple computer servers and which provides virtual control function for a single instantiation of a hardware resource of the computer server system, wherein the hardware resource is shared between each of the computer servers.

Generating a physical circuit board design. The physical circuit board is designed based on a design data set containing multiple electronic components. In a first step, the electronic components are classified by assigning them either to a group of so-called Core Components or to a group of Application Specific Components. Subsequently, a circuit board layer structure is generated. The layer structure includes a Core Layer Structure located in the center of this layer structure. The components are placed onto the board's layer structure in such a way that the Core Components are placed onto the Core Layer Structure. Finally, a design macro of the resulting physical design is generated and the circuit board is assembled.

A Common System Storage Repository replaces all the different system support storages distributed across a server system topology transparent to various subsystems by providing a central non-volatile repository for all the different system data. Each of the various subsystems communicate with the Common System Storage Repository via the individual system support storage interfaces.

System support storage and computer system

A network of processing units having at least one switch that allows disruption of the network between a first and a second processing units is provided. Disruption of the network by means of the switch effectively disconnects the first processing unit from the network and couples the first processing unit to a controller of the network. The controller is adapted to exchange data with the disconnected processing unit and thereby allows selective and direct data exchange with a selected processing unit. In particular, in the framework of heterogeneous and hierarchical networks of processing units, the switch techniques provide direct access to processing units and sub-networks and allow for an efficient and fast performance of diagnostic and maintenance procedures of sub-networks and their corresponding processing units, such as performing a flashing procedure.

The present invention relates to the field of embedded processing systems and electronic control units (ECUs) and to autonomic embedded computing solutions. The present invention proposes to remove or extract the application-specific support functions and respective I/O subsystems from the main processors or controllers of the system, to include said extracted circuits into a respective number of ASIC chips or the like, and to connect them preferably via a supervising General Controller Unit () to a plurality of standard and low-price processors (), which have the task to supply the ASIC and the multiple functions thereof with enough computing power.

In a processor system for audio processing, such as voice recognition and text-to-speech, a dedicated front-end processor, a core processor and a dedicated back-end processor are provided which are coupled by dual access stack. When an analog audio signal is inputted core processor is invoked only when a certain amount of data is present in the dual access stack. Likewise the back-end processor is invoked only when a certain amount of data is present in the dual access stack. This way the overall processing power required by the processing task is minimized as well as the power consumption of the processor system.

A Dynamic Storage Subsystem Morphing (DSSM) mechanism () is connected to a plurality of storage subsystem resources, which reserve some storage area each non-donor ECU (), ready for a 'slot-down/up' access by a respective non-donor ECU having a storage subsystem () breakdown. The slot-down process enables the use of a high physical address range by the non-donor processor provided with addressing capabilities sufficient only for addressing lower ranges.
