Production-grade IEEE 1588 PTP Grandmaster & Slave stack orchestrated on BeaglePlay (AM62x) & BeagleBone Black (AM335x). Powered by PREEMPT_RT Linux, hardware timestamping, and verified with oscilloscope for userspace jitter measurements.
A precision timing control room for building, observing, measuring, and tuning multi-hop PTP clock cascades on one Linux host.
High-performance NTP/PTP time synchronization daemon in Rust — NTPv4, NTS (RFC 8915), PTP/IEEE 1588, clock discipline & Prometheus metrics in one lightweight binary.
AI-assisted multi-reference timekeeping for packet-level synchronization on commodity networks
IEEE-1588 PTP hardware timestamping + latency-measurement unit: DDS clock core, handshake CDC, log2 histogram over AXI-Lite, Simulink PI servo with bit-exact RTL diff
PTP (IEEE 1588-2008) hardware timestamping over 10BASE-T1S on ATSAME54P20A + LAN8651 (Harmony 3), with a Python test harness, adaptive drift filter and cross-board sync measurements.
AI-native O-RAN Open Fronthaul S-plane timing security with fault-vs-attack discrimination, digital-twin verified recovery, linuxptp/netem, and TIMESAFE validation.
Experimental dual-FPGA PTP closed-loop synchronization: reusable AXI node IP and pure-RTL reference master.
Editable visual map of ITU-T telecom PTP profiles and synchronization standards
