Synopsys, Inc. says it has enhanced the DesignWare Ethernet MAC 10/100/1G IP to include support for the latest IEEE 1588 specification as well as an interface to the ARM AMBA 3 AXI protocol.

The IEEE 1588 specification provides a standard method to synchronise devices on a network with sub-microsecond precision. This capability is a key requirement for consumer products in digital home applications as well as measurement and control systems.

The addition of the AMBA 3 AXI interface enables designers to easily add Ethernet connectivity to their SoCs. Synopsys' DesignWare Ethernet IP solution is certified by the University of New Hampshire Interoperability Lab (UNH-IOL), which demonstrates proven interoperability and conformance to the IEEE standards.

The IEEE 1588 specification implements real-time clocks to precisely synchronise all of the connected devices, allowing systems to exchange the required amount of data such as audio and video streams, within a predefined time. Support for this specification has been added to the silicon-proven DesignWare Ethernet MAC 10/100/1G IP to help designers quickly incorporate this functionality into their SoCs.

By using the new AMBA 3 AXI interface available in the DesignWare Ethernet IP, designers can leverage this high-performance on-chip bus to deliver higher throughput designs with access to a wealth of Ethernet-based systems and peripherals.

The DesignWare Ethernet MAC 10/100/1G IP solution with IEEE 1588 and AMBA 3 AXI interface support is available now.
