由于锁存器和组合逻辑的灵敏度增加以及芯片上晶体管数量的增加，逻辑中的软错误在计算机系统设计中变得越来越重要。与此同时，计算机系统的用户继续期望更高水平的系统可靠性。因此，在硬件和固件软件缓解方面的投资可能会继续增加。IBM eServer z990系统旨在检测和恢复无数软错误和永久错误实例。描述了z990处理器和“嵌套”芯片内的错误检测和恢复，以及针对软错误的系统级保护。
Soft errors in logic are becoming more significant in the design of computer systems due to increased sensitivities of latches and combinatorial logic and the increased number of transistors on a chip. At the same time, users of computer systems continue to expect higher levels of system reliability. Therefore, the investment in hardware and firmware software mitigation is likely to continue to rise. The IBM eServer z990 system is designed to detect and recover from myriad instances of soft and permanent errors. The error detection and recovery within the z990 processors and the "nest" chips is described with respect to the system level protection against soft errors.
