Abstract: A video output supervisor includes a test region indicator for verifying that the commanded output to specific areas of a display is valid. Areas reserved displaying safety-critical data in the data frame to be displayed can be supervised for the presence and status of display indicators of the safety-critical data. The confidence of the supervision can be increased by measuring other display and frame parameters in conjunction with supervising the indicators of the safety-critical data.

Abstract: An error monitor receives a first list of selected system events with each selected system event having an associated range. The occurrence of each selected system event is counted over a selected time period. An error indication is provided based on a comparison of each of the counts of the occurrence of each selected system event over the selected time period with the associated range. Operational profiles are used to store lists of selected system events with each selected system event having an associated range for each operational profile.

Abstract: A system comprises first timing logic configured to produce a first signal and second timing logic configured to produce a second signal. The system also comprises processing logic coupled to the first and second timing logic. The system further comprises clock logic that determines elapsed time using the first signal. The processing logic compares the first and second signals and, based on the comparison, the system adjusts the elapsed time.

Abstract: Various systems and methods for implementing multi-display driver systems are disclosed. As one example, a display system is disclosed that includes a display driver, a processor, a computer readable medium, and a splitter device. The computer readable medium includes instructions executable by the processor to configure the display driver to provide a display output set for a virtual display. The splitter device is operable to receive at least a portion of a display output set, and to provide a first display output to drive a first display and a second display output to drive a second display based on the portion of the display output set.

Abstract: A CPU-based system 10 and method for testing embedded memory. The technique employs the on-chip CPU 20 itself to test the embedded memory 24. An assembly code program is loaded into the device under test (DUT) 12 to test the memories, determine a repair solution, and write out the repair solution and raw failure information to the tester for defect analysis. The test is driven by an external programmable clock that is provided by the tester to allow the DUT 12 to run up to its maximum input clock rate in order to maximize throughput. The test is not dependent on the pattern rate of the tester.
