Zylogic's Ethernet Bridge Solution helps solve the problem of building connections between an Ethernet port and other communications protocols, such as USB, CAN, RS-232, and I2C. By using FastChip IP in conjunction with the Configurable System Logic and Advanced DMA controllers in Zylogic's ARM7TDMI-based CSoC, designers can easily bridge 10/100 Ethernet with any interface.
