The demand for predictable timing behavior is characteristic for real-time applications. Experience has shown that this property cannot be achieved by software alone but rather requires support from the processor. This situation is analyzed and mapped to a design rationale for SPEAR (Scalable Processor for Embedded Applications in Real-time Environments), a(More)
This paper presents the hardware implementation of a stereo vision core algorithm, that runs in real-time and is targeted at automotive applications. The algorithm is based on the sum of absolute differences (SAD) and computes the disparity map using 320 times 240 input images with a maximum disparity of 100 pixels. The hardware operates at a frequency of(More)
The introduction of computer-controlled intelligent safety and comfort features has turned cars into complex distributed computing systems. In such a system the proper operation of the communication backbone as well as the proper interaction of components from different vendors must be ensured for all configurations and operating conditions. This(More)
With clock rates beyond 1 GHz, the model of a system wide synchronous clock is becoming difficult to maintain; therefore, asynchronous design styles are increasingly receiving attention. While the traditional synchronous design style is well-proven and backed up by a rich field experience, comparatively little is known about the properties of asynchronous(More)
The SAE has classi ed automotive electronics into two major categories body electronics and system elec tronics The latter SAE class C comprises safety crit ical functions that are of vital importance for the move ment of the vehicle This paper presents a prototype implementation of TTP a time triggered communica tion system developed for this type of(More)
The paper analyzes the prerequisites for the determination of most efficient combinations of error detection mechanisms based on the results of fault injection experiments. Two crucial requirements are identified: (1) for the classification of the experiment outcome it is essential to observe whether a system failure actually occurs. Error detections should(More)
