In this paper we propose a novel error control scheme to cope with errors affecting the communication links of a NoC. Our scheme can be configured in Correction Mode, Detection Mode, and Mixed Mode, depending on the particular application, thus allowing to meet different Quality of Service (QoS) levels in terms of error control. For each configuration mode, we propose different error control policies and we consider SEC Hamming codes, SEC/DED Hsiao codes, and Symbol Error Correcting codes. We evaluate advantages and drawbacks of each approach, in terms of signal integrity, area overhead and impact on performance.

Abstract

In this paper we propose a novel error control scheme to cope with errors affecting the communication links of a NoC. Our scheme can be configured in Correction Mode, Detection Mode, and Mixed Mode, depending on the particular application, thus allowing to meet different Quality of Service (QoS) levels in terms of error control. For each configuration mode, we propose different error control policies and we consider SEC Hamming codes, SEC/DED Hsiao codes, and Symbol Error Correcting codes. We evaluate advantages and drawbacks of each approach, in terms of signal integrity, area overhead and impact on performance.
