Abstract:
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 (12) to a plurality of standard and low-price processors (40), which have the task to supply the ASIC and the multiple functions thereof with enough computing power.
Abstract:
The invention relates to a bi-directional optical data transfer system. The data is transferred by a diffuse light between several electronic components (22) with several transmission links, wherein each transmission link is provided with a covering (12) to prevent said transmission links from interfering with each other.
Abstract:
The present invention provides a network of processing units having at least one switch that allows to disrupt the network between a first and a second processing unit. 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 to selectively and directly exchange data with a selected processing unit. In particular in the framework of heterogeneous and hierarchical networks of processing units, the invention provides direct access to processing units and sub-networks and allows for an efficient and fast performance of diagnostic and maintenance procedures of sub-networks and the their corresponding processing units, such as e.g. performing a flashing procedure. By selectively disconnecting a sub-network, flashing can be performed selectively without shutting down of the entire network. Moreover, the invention allows for simultaneous flashing of various sub-networks and for autonomous compensation of network failures by means of the dynamic network restructuring.

Abstract:
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.

Abstract:
In a processor system (1) for audio processing, such as voice recognition and text-to-speech, a dedicated front-end processor (12), a core processor (16) and a dedicated back-end processor (21) are provided which are coupled by dual access stack (7) and (8), respectively. When an analog audio signal is inputted core processor (16) is invoked only when a certain amount of data is present in the dual access stack (7). Likewise the back-end processor (21) is invoked only when a certain amount of data is present in the dual access stack (8). This way the overall processing power required by the processing task is minimised as well as the power consumption of the processor system (1).
