The present invention is directed to a method of and and apparatus for continuously generating desired pulses during assumed successive desired pulse intervals with a very high time resolution by digitally predetermining the time values related to the start of the desired pulse intervals. These time values are divided into coarse and fine time rasters and coarse pulse intervals are generated from the assumed desired pulse intervals. The coarse pulses in the coarse time raster are generated from the desired pulses and each coarse pulse start and coarse pulse end, respectively is associated with a coarse pulse correction value. By adding the coarse pulse interval correction value to the coarse pulse correction value for the start and the end of the coarse pulse, respectively, a sum correction value is obtained and divided into a partial value associated with the fine time raster. The partial value of the sum correction value is used as a control value for a selected time delay for the coarse pulse edge shifted.

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 processing unit (100) with a processor (110) for processing an operation code and a method for processing the operation code in the processing unit (100). The processor (110) comprises an operation code control unit (200) for receiving and processing the operation code in a boolean circuit (230) and generating a logical result thereof, and a next address control unit (210) comprising a multiplexing unit (250) with a plurality of input lines (A-D) selectable by the multiplexing unit (250) by means of the logical result of the boolean circuit (230). The processor (110) is triggerable by a trigger signal (CLOCK) and each operation code is processable by the processor (110) between successive trigger signals (CLOCK). When the trigger signal appears, the processor (110) issues a signal comprising an address of the operation code to be processed to the control memory (129) and/or a user data memory (140). The operation code corresponding to that address is loaded from the control memory (120) to the processor (110) and processed therein. One result of this processing is that the address of the successive operation code, which will be processed when the successive trigger signal appears. This loading and processing of operation code happens continuously in each cycle between successive trigger signals, until the end of program is reached or an interrupt signal is calling a stop routine. Each operation code is processed between successive trigger signals (or within one CLOCK cycle) allowing a predictable timing of a sequence of operation codes so that a real time condition is achievable.

A circuit for generating product-specific digital test signals for testing memories, etc., the test signals comprising a test pulse occurring during a pulse interval and generated from predetermined data and timing signals. A format memory (7-11) stores addressable test signal formats (in the form of digital values denoting the test signals curve unrelated to time) for each data signal. These digital values are read out time parallel to each other and are combined by a flip-flop circuit (7-24) in the order of their occurrence during the pulse interval with timing signals for the respective data signal to form a control signal. The internal signal delay of the flip-flop circuit determining the generation of the test signals is invariably of the same value. This circuit may not only be used for test purposes but also generally for computer control, in particular for addressing main memories and buffers.

A frequency and timing generator is presented with high accuracy and frequency resolution and no switching time between different timing cycles for a wide applicable frequency range, wherein the repetition rate of the timing cycles is not limited by the processing speed of the components. The frequency and timing generator according to the invention is accomplished by an apparatus for parallel processing of a series of timing signals comprising at least one processing unit for processing and calculating time values from timing parameters representing the series of timing signals, an output unit for outputting the series of timing signals, and an input unit for inputting the timing parameters. The sequences of n successive timing parameters to be parallelly processed are distributable by the input unit to n processing units. A first time value from a first one of the timing parameters is calculatable by a first one of the processing units, and a succesive time value is calculatable by a succesive one of the processing units from the corresponding successive timing parameter of the sequence and the calculated time value of the respective preceding timing parameter.

The present invention discloses method for packaging and assembly of electronic units comprising a multi-planar board system in which each single planar board provides electrical contacts and/or signal drive to its successive planar board via a flexible cable forming the only connection between successive planar boards. In its packaged position the planar boards are laid upon one another without affixing them with each other or affixing them with the housing of the electronic unit, wherein the packaging of the planar boards preferably forming a daisy chain. Positioning and adjusting of the planar boards to each other is mainly achieved by the cover element being wrapped around all surfaces of the planar boards during the packaging process, positioning and clamping of the packaging of the planar boards within the housing is mainly achieved by the self-adapting suspension during the assembly process of the electronic unit into the housing. The cover element separating and concurrently adjusting each planar boards to each other has isolating, stabilizing, heat draining, and flexible attributes. The electronic unit is preferably arranged in a screw-less, and scalable housing.
