Abstract:
An electronic control system for controlling the function of a processing system is provided, especially for the use in an automotive vehicle, wherein said control system comprises a plurality of logical control elements, each of which is especially adapted to perform special tasks, whereby each of said control elements is able to communicate with every other control element.
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:
An electronic system is provided having at least first and second sub-systems (24, 25, 26) and a memory (54) for storage of boot-images of the respective sub-systems. A controller 31 loads the boot-images stored in the memory (54) into the respective sub-systems (24, 25, 26) in sequential order via multiplexers (29, 41 and 48). This allows to utilize an inexpensive memory device for the memory (54) and to reduce the overall code size.
Abstract:
A principle for handling system failure situations thereby maintaining minimum fault recovery time and providing high system availability is described, especially for controlling the system behavior in fault situations of Electronic Control Units used in automotive vehicles. This principle is providing unique solutions for fault analysis, fault recovery definition and system re-vitalization. It is a key attribute of the principle keeping the demand for hardware and software overhead at a minimum. The method applies graceful degradation of system functionality, allowing to achieve the implementation of cost effective systems.

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 process for the generation of pulse sequences which are not separated from each other in time is used for testing a memory. When a specific numerical value has been attained, pulse generation is initiated by a degressive counter which is controlled by clock pulses. The degressive counter may receive a starting value from a memory. Before the specific value has been attained, the resetting of the counter at a new starting value, also provided by the memory, is carried out. This occurs at the instant when the counter would normally have attained the value of zero in its program of counting.

Abstract:
Interrupt controller comprises parallel input (30) for receipt of a first interrupt request signal, means (31) for output of a second interrupt request signal as a reaction to the first interrupt request signal, state processing means (32) for determining interrupt priority, memory (37) for storing addresses of interrupt servicing programs whereby each servicing program handles an interrupt signal and means (36) for selection of an address based on the priority.
