USB 3.0 및 PCI Express 인터페이스를 위한 Elastic Buffer의 설계 및 구현

An elastic buffer stated in USB 3.0 and PCI Express specification is designed and implemented. The elastic buffer minimizes the probability of having metastable signals created while transferring signals across two different clock domains. It also prevents overflow and underflow due to clock frequency difference between CDR-recovered clock and the receiver"s internal clock by handling dummy signals.
