Systems and methods are provided to generate time data according to a nominal frequency and based on an available frequency. A hardware clock of the system can operate according to the available frequency. The system can identify a difference between the available frequency and a nominal frequency. Based on the difference, the system can generate time data according to the nominal frequency. To generate the time data, for each clock cycle of a plurality of clock cycles according to the available frequency, the system can determine whether to increment or maintain a value of the time data for a prior clock cycle of the plurality of clock cycles. The system can perform one or more functions based on the time data.

Configurable system counter based on a hardware clock frequency

Techniques to prioritize serially transmitted data are described. The sequence of serial data segments being transmitted across a communication interface is modified such that prioritized segments that may require a higher refresh rate are transmitted more frequently than regular data segments. A prioritization configuration register can be implemented in both the transmitter and the receiver such that both sides are programmed with the altered sequence of transmission. The prioritization configuration stored in the prioritization configuration register can indicate the points in the sequence where the out-of-order transmission occurs, and which data segments are transmitted in them. The transmitter can use this information to serialize the data segments according to the prioritization, and the receiver can re-parallelize the received data as indicated by the altered sequence.
