Serial RapidIO robustness enhancement scheme

Abstract

Robustness enhancement scheme in Serial RapidIO (SRIO) interconnect is proposed to overcome the performance degradation caused by noise and Electromagnetic Interference (EMI). The main idea of this scheme is the adaptive speed transition and mode conversion. Adaptive speed transition can improve average throughput and reduce delay in high Bit Error Rate (BER) environment. Mode conversion is to conquer frequent usage of feedback channel. Simulation shows that the scheme of combining adaptive speed transition with mode conversion leads great performance enhancement in SRIO network.
