Ethernet Switch Lite 1G

General Description

Comcores Lite Ethernet Switch (LES) IP core is a highly configurable and size optimized implementation of a non-blocking ring switch that allows continuous transfers between up to 73 ports Ethernet ports via 1 Gbps GMII interfaces. The switch supports MAC learning and implements store-and-forward switching approach in order to fulfill Ethernet standard policy regarding frame integrity checking.

The switch supports up to 73 ports where each port provides GMII native interface for Ethernet PHY devices.

The number of ports and rings within the switching fabric are configurable at compile time.

Comcores Lite Ethernet Switch (LES) IP core is a silicon agnostic implementation targeting any ASIC, FPGA or ASSP technologies.

Key Features


Ultra Compact Size
  • Rings in the switching fabric can be downsized to reduce resource usage at the cost of blocking
Delivers Performance
  • Automatic MAC addresses learning and aging
  • Programmable firmware operation with Static or Dynamic (Learning, Aging) switching tables
  • Full duplex Ethernet interfaces
  • GMII interfaces for attaching to an external Physical Layer device (PHY)
  • Manual insertion of unicast/multicast entries to the MAC lookup table
  • Runtime configurable port based VLAN ID and VLAN trunk assignment to each port

Request Datasheet:

  Highly Configurable
  • Up to 73 ports configurable at compile time
  • Configurable queuing behavior (round-robin, fair queuing, etc.)
  • Support Ethernet Multicast, Broadcast with flooding control to avoid unnecessary duplication of frames
  • Configurable support for 1588 PTP Transparent Clock functionality
Silicon Agnostic
  • Designed in VHDL-93 and targeting any RTL implementation like ASICs, ASSPs and FPGAs.


The IP core comes deeply verified and with an extensive documentation that among others include Product Brief and User Manual. The core will by default come in an encrypted format. Source code option is available.
