The LLEMAC-1G implements an Ethernet Media Access Controller compatible with the 10/100 Mbps IEEE 802.3 and 1Gbps IEEE 802.3-2002 specifications. Featuring extremely low egress and ingress latency, the core is ideal for the implementation of TSN Ethernet nodes, live streaming and other devices requiring minimum latency in the reception and transition of Ethernet frames.
The core supports full-duplex operation, supports jumbo frames, provides statistics counters, and it is easy to integrate and implement. The LLEMAC-1G exchanges data with the host system via a byte-wide streaming interfaces, and connects to the external PHY via an MII, GMII or RGMII interfaces. An independently clocked, 32-bit wide memory mapped interface provides access to the cores control and status registers. The default core interfaces comply to the Avalon standard, but AMBA™ AHB or AXI can also be made available upon request.
