摘要： A system for performing diagnostic checks on a data message transmitted from a sensor and received by a receiver includes a receiver clock tick counter, a prescaler counter, a calibration pulse detector, a nibble counter, and a calculator. The system receives first and second data messages transmitted from the sensor. Pulse widths of first and second calibration pulses of the first and second data messages, respectively, and lengths of the first and second data messages are measured using the receiver clock tick, prescaler, and nibble counters based on a compensated receiver clock signal. Thereafter, the pulse widths of the first and second calibration pulses and the lengths of the first and second data messages are compared using the calculator to perform the diagnostic checks.

摘要： A memory error management system connected to memory channels for managing errors detected in corresponding memory devices includes a reporting table including a list of historically reported errors, a binary value representing the current error status of the memory channels, a uniqueness check module for checking whether a historically reported error is reappearing as a current error, an error mask register for generating a masked binary value representing unique current errors in the memory channels, and a channel arbitration module for decoding the channel identifiers of corrupted memory channels from the masked binary value and storing the decoded channel identifiers into the reporting table.

摘要： A method and system for estimating and compensating for variation between a receiver clock and a transmitter clock, where a receiver utilizes a high frequency clock signal to generate a receiver clock and then adjusts the receiver clock to compensate for variations between the receiver and transmitter clocks. The adjusted receiver clock is used to sample nibble pulses in a received data frame. Counter based compensation of the receiver clock eliminates the need for the receiver to perform floating point calculations, improves the accuracy of nibble pulse sampling and also reduces area and power consumption of the device.

摘要： A tamper detector has tamper detection logic connected to tamper detection ports through a tamper detection interface. A real-time clock (RTC) provides a clock signal and has a battery. A processor is powered by an external power supply in a powered operational mode and has a power-off mode. In a wake-up configuration, a wake-up signal on a specific I/O port awakens the external power supply from the power-off mode to supply power to the RTC and the tamper detection interface when power from the battery is unavailable. The tamper detection ports continue to function despite removal or discharge of the battery without ESD concerns. The specific I/O port optionally may be configured for passive tamper detection.
