WebµC/CPU timestamps emulate a real-time 32- or 64-bit timer using any size hardware (or software) timer. If the hardware (or software) timer used has the same (or greater) number of bits as the 32- or 64-bit CPU timestamps, then calls to CPU_TS_Get() functions return the timer value directly with no additional calculation overhead. But if the timer has less bits … Webolika system såsom CPU, I/O, nätverk och på operativsystemet. Data ... cision is aﬀected by system load using two Intel Galileo development boards.

WebThe CPU writes all PHYs with local time at the next load or save pulse, and then sets the load bit in each PHY. This time includes the known PCB trace delay on the load or save pin of each PHY, as well as the fixed load latency as defined in Synchronizing to a PTP Master. Local time is loaded into all PHYs on the next pulse on the load/save pin.
