USB 3.0 Using FPGA Optimization for 8b/10b Encoder/Decoder

Abstract

USB is a transmission interface used to connect two devices, transfer data or charge. The transmission speed of USB3.0 is 5Gbps, while the transmission speed of USB2.0 is only 480Mbps, which is 10 times faster than USB3.0, This article implements 8b/10b encode and decode conversion, RX_STATUS shows the status of each step, and PLL can switch the clock.
