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:
In a method for the generation, without dead time, of pulses appearing in successive pulse intervals, with a high time resolution of the pulse intervals and of the pulses, the signals characterizing start (IIN1A, IIN2A) and end (IIN1E, IIN2E) of a pulse interval are generated under storage control by an oscillator (1) for giving coarse time raster values, and a delay circuit (3, 4) series-arranged with the oscillator (1) and with selective (7, 8) delay circuit taps (5, 6) for giving fine time raster values. The signals characterizing the pulse intervals are alternatingly applied to one of two paths (path I, path II), such that the signal characterizing the respective pulse interval start coincides with the coarse time raster predetermined by the oscillator (1). For each path, the leading and trailing edge of a pulse to be generated within a pulse interval is derived via oscillator clock-driven counters (45, 47, 46 and 48) loadable with a count, upon a specific count being reached. Series-arranged to the counters for generating the leading and trailing edges ( 45, 46 and 47, 48) a respective common delay circuit (51 and 52) is provided with storage-controlled (43, 44) selectable delay line taps (62 and 79) for a fine time raster. The pulse information generated on both paths is joined on a common line (65).

Abstract:
This discloses a pattern generator having a programmable product cycle timer in which a pulse train, i.e., the pattern generated, having a time raster measurable to one nanosecond can be repeated or switched from a first pulse frequency to a second pulse frequency without the usual transient switching periods between pulses. The invention accomplishes this by providing the generator with a cycle timer using a ten nanosecond clock operating in conjunction with a ten nanosecond down counter so that a pre-selected time interval, before the end of the pulse is achieved, a test is made to determine if a required condition needing a different pulse frequency exists. If such a condition does not exist the present pulse frequency is reinitiated so that at count 0 it is repeated without delay. If the required condition does exist loading of the needed pulse frequency is initiated so that upon termination of the presently existing pulse at count 0, the newly selected pulse will be introduced into the product being tested without delay. A programmable cycle timer is provided to permit the implementation of pulses which has a time raster that is other than a ten nanosecond multiple.
Abstract:
Additional entities, such as consumer electronic (CE) devices may be integrated into a vehicle electronics system using generic device classes. The vehicle electronics system (10) comprises a human machine interface (HMI), and at least one generic physical and logical interface, A device integrator (20) is connected to the vehicle electronics system (10) via its generic interface and provides connections to additional entities, which may be hot pluggable. The device integrator (20) classifies the connected consumer electronics devices, such as mp3 media players, DVD plaers, gaming consoles, according to their functionality into a set of generic device classes. The integrator translates the individual logical interface protocol of each subsystem group into a generic communication protocol, providing a software or logic driver which is supported by the in car electronics system (10), such that a connected entity may be operated via the HMI without loading any entity specific executable code into said vehicle electronics system. The integration framework may verify the source and integrity so that trusted software is uploaded, to display a specific screen layout for each device class. The integrator may include a USB connection or an FM transmitter for physical adaption to a wireless interface for the vehicle.
Abstract:
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.
