A high performance inter-chip fiber communication scheme with short frame protocol

Optical interconnection is a potential substitute for electrical interconnection in the chip integration field, as it can ultimately solve the problems such as crosstalk and electric migration brought by electrical wires. In the paper, a short frame asynchronous optical communication protocol is proposed to implement the inter-chip optical communication between the microprocessor and the static memory chip. Accordingly, an inter-chip fiber communication system is designed with FPGA to implement the protocol and to verify the inter-chip fiber communication. The experimental results show that the proposed method can work correctly and has a high performance.
