Abstract:
A system timer bus used by the processor elements in an ARM-based system on a chip (SoC) is driven using a Precision Time Measurement (PTM) value. This allows the processor elements to be synchronized to the PCIe ports that use PTM. When two SoCs are connected using PCIe links, this example allows the processor elements in both SoCs to be synchronized. As the processor elements are synchronized, associated tasks on the two SoCs are synchronized, so that overall operations are synchronized.
