摘要： A method of automatically invoking a recoverable and fault tolerant implementation of the complemented/recomplemented (C/R) error correction method without the assistance of a service processor when an excessive error is detected in main storage (MS) by ECC logic circuits. An excessive error is not correctable by the ECC. These novel changes to the C/R method increase its effectiveness and protect the C/R hardware against random failure. Further, if an excessive error is corrected in a page in MS, an excessive error reporting process is provided for controlling the reporting using a storage map to determine if a previous correction in that page has been reported. If it has been reported, then no further reporting of soft excessive errors is made for that page. A service processor is signaled in parallel to update its persistent copy of the storage map so that on a next initializations of MS the memory map can be restored in the memory. The memory map is used to assist the repair of failing parts of MS, and is reset after MS is repaired.
摘要翻译：一种在由ECC逻辑电路在主存储器（MS）中检测到过大的错误的情况下，无需服务处理器的协助，自动调用补充/重新补码（C / R）纠错方法的可恢复和容错实现的方法。 ECC不能纠正过大的错误。 C / R方法的这些新变化提高了其有效性，并保护C / R硬件免受随机故障的影响。此外，如果在MS中的页面中校正了过多的错误，则提供了过多的错误报告处理，用于使用存储映射来控制报告，以确定是否已经报告了该页面中的先前校正。如果已经报告，则不会再为该页面报告软过度错误。服务处理器并行发信号以更新其存储映射的持久副本，以便在MS的下一个初始化时，可以在存储器中恢复存储器映射。存储器映射用于协助修复MS故障部件，并在MS修复后重置。

摘要： A data processing device and methods thereof are disclosed. The data processing device can operate in three different modes. In a first, N-bit mode, the data processing device performs memory accesses based on N-bit values and performs arithmetic operations using N-bit values. In a second, hybrid N-bit/M-bit mode, the data processing device performs memory accesses based on M-bit values, where M is less than N, and performs arithmetic operations using N-bit values. In a third, M-bit mode, the data processing device performs memory accesses based on M-bit values and performs arithmetic operations using M-bit values. The three modes provide for compatibility with a wide range of applications. Further operation in the M-bit mode can provide a power savings when implementing applications compatible with that mode.

摘要： A data processor includes a first bit field of a first plurality of bits representing a mantissa of a floating point number and a second bit field of a second plurality of bits representing an exponent of the floating point number. The first plurality of bits is partitioned into a plurality of regions, each of the plurality of regions comprises more than one bit of the first plurality of bits. A leading zero anticipator or other type of leading bit indication circuit is coupled to each region and determines a position of a leading bit of the first plurality of bits. A normalizer is coupled to receive a region of the plurality of regions that contains the leading bit, the normalizer may normalize or denormalize the region to produce a normalized or denormalized floating point number.
