    Abstract: A system timer bus used by the processor elements in systems, such as 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.

    Abstract: A video encoder including a first buffer containing a plurality of data values defining a macroblock of pixels of a video frame. The video encoder also includes a second buffer and an entropy encoder coupled to the first and second buffers and configured to encode a macroblock based on another macroblock. The entropy encoder identifies a subset of the data values from the first buffer defining a given macroblock and copies the identified subset to the second buffer, the subset of data values being just those data values used by the entropy encoder when subsequently encoding another macroblock.
