1G Ethernet Switch
Comcores Lite Ethernet Switch (LES) IP core is a highly configurable and size optimized implementation of a non-blocking crossbar switch that allows continuous transfers between up to 36 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 36 ports where each port provides GMII native interface for Ethernet PHY devices. The number of ports are configurable at compile time.
Comcores Lite Ethernet Switch (LES) IP core is a silicon agnostic implementation targeting any ASIC, FPGA or ASSP technologies.
