Abstract: A multi-processor system includes a first processor that includes a first time base counter that outputs a first time base count, a second processor that includes a second time base counter that outputs a second time base count, and a communication bus. The first and second processors exchange the first and second time base counts on the communication bus. The first and second processors determine a skew based upon a difference between the first and second time base counts, and the first and second processors synchronize with each other based upon the skew.

Abstract: Multiple positions within a mechanical system are measured with a plurality of sensors including at least one 4-wire and at least one 5-wire sensor. The 5-wire sensor has two output voltage signals sent to a signal conversion processor, and the 4-wire sensor also sends a signal. A sum is created of the two voltage signals from the 5-wire sensor. An excitation voltage supply supplies a common excitation voltage to both sensors. Feedback of the excitation voltage is measured by the signal conversion processor. The excitation voltage feedback is utilized to ratio-metrically correct a position feedback signal from the 4-wire sensor at the signal conversion processor. The signal conversion processor is able to synthesize a signal indicative of the excitation voltage from the two voltage signals sent from the 5-wire sensor in the event the excitation voltage feedback is not received at the signal conversion processor.

Abstract: In one example, a device includes at least one processor, a transceiver configured to send and receive data, and at least one memory device. The at least one memory device includes a range of physical memory addresses divided into a plurality of physical memory partitions that each includes a sub-range of the range of physical memory addresses and corresponds to a range of virtual memory addresses. Instructions encoded in the at least one memory device cause the at least one processor to receive a memory address request configured to request access to a requested physical memory address within the range of physical memory addresses, determine that the requested physical memory address is associated with one of the plurality of physical memory partitions, determine a virtual memory address corresponding to the requested physical memory address, and access the requested physical memory address via the determined virtual memory address.
