Design and implementation of elastic buffer for Universal Serial Bus 3.0

Abstract

To avoid the timing errors caused by the asynchronous control of elastic buffer between read and write operations. In this paper, a new skip (SKP) adding technology is proposed, which is achieved by the suspending of the read pointer. Based on the proposed new mechanism, a new elastic buffer is designed and realized under the TSMC65nm CMOS technology. The post simulation results show that, the presented elastic buffer can complete SKP adding and removing function correctly, and the clock frequencies can reach 500 MHz with tiny changes in area, energy consumption and speed of reading. It can be applied to the design and optimization of USB3.0.
