本文提出了一种在线检测寄存器或寄存器堆等微处理器存储元件中多个比特错误的方法--交叉奇偶校验。辐射或电磁影响引起的暂态或“软”误差是这项工作的重点。特别是对于寄存器堆或寄存器组，提出了一种易于实现的纠错方法，该方法可以通过软件例程或附加硬件来执行。该方法基于交叉奇偶向量的逻辑解释。
This paper proposes the cross-parity check as a method for an on-line detection of multiple bit-errors in storage elements of microprocessors like registers or register files. Transient or 'soft' errors caused by radiation or electromagnetic influences are the focus of this work. Especially for register files or register groups, an easy implementable error correction method is proposed, which can be performed by software routines or additional hardware. The method is based on the logical interpretation of cross-parity vectors.
