Overview

The IEEE802_1AS is a complete IEEE 802.1AS hardware stack that enables the simple and rapid development of time-aware nodes for AVB/TSN networks such as automotive Ethernet. It operates fully autonomously and provides timing and synchronization according to IEEE 802.1AS for full-duplex, point-to-point Ethernet links. The core is designed to operate next to an Ethernet Media Access Control unit (eMAC) and attached to that eMAC’s data-interface towards the host system. It automatically synchronizes its internal real-time clock (RTC) to that of the grandmaster by inserting and extracting IEEE 802.1AS frames in and from the Ethernet traffic. The core fully offloads the host processor from any IEEE 802.1AS related processing, and at the same time enables the development of time-aware applications: it provides timestamps, periodic event triggers, and alarms to the host system, using host processor Interrupt lines or dedicated-low latency interface signals.

Features

    Device Utilization and Performance

    The IEEE802_1AS core can be mapped to any Intel FPGA device (provided sufficient silicon resources are available) and optimized to suit the particular project’s requirements. The core occupies approximately 4,000 ALMs. Please contact CAST to discuss resource utilization and performance for your application and target device.
