摘要： A management system that controls a restart interface in a data processing system. The management system switches control of the interface from a distributed network managed by the caches to the management system. The management system is capable of detecting errors and seizing control of the interface in order to remedy any errors that occur within the interface.

摘要： A method, system and computer program product for optimizing EPN to RPN translation when a data miss occurs. The method, system and computer program product take advantage of the high-likelihood of finding the matching PTE in the first half of the PTEG and utilize early data-coming signals from the L2 cache to prime the data-flow pipe to the D-ERAT arrays and requesting a joint steal cycle for executing the write into the D-ERAT and a restart request for re-dispatching the next-to-complete instruction.

摘要： A system and method for checking the test logic contained in a computer memory system during POST such that any errors can be determined and made available to the system software prior to beginning processing operations. Single and double bit errors are induced which the ECC logic must identify and correct. The CPU compares the data that is written to memory with the data that is read back. Thus, since it is known that an error occurred, due to the induced error provided by the present invention, identical data will verify that the ECC correction logic is working properly. More specifically, a multiplexer is provided in the data write path which substitutes a constant set of identical bits for the actual data generated by the CPU. ECC bits are generated based on the actual generated test data, rather than the inserted identical bits. The substituted data bits and generated ECC bits are then stored in memory. An error condition is identified when the data and ECC code is read back from memory. The correction logic then corrects the data, in the case of a single bit error, such that the data read by the CPU is the same as the originally generated data.

摘要： An apparatus and method selectively invalidate entries in an address translation cache instead of invalidating all, or nearly all, entries. One or more translation mode bits are provided in each entry in the address translation cache. These translation mode bits may be set according to the addressing mode used to create the cache entry. One or more “hint bits” are defined in an instruction that allow specifying which of the entries in the address translation cache are selectively preserved during an invalidation operation according to the value(s) of the translation mode bit(s). In the alternative, multiple instructions may be defined to preserve entries in the address translation cache that have specified addressing modes. In this manner, more intelligence is used to recognize that some entries in the address translation cache may be valid after a task or partition switch, and may therefore be retained, while other entries in the address translation cache are invalidated.
摘要翻译：一种装置和方法选择性地使地址转换高速缓存中的条目无效，而不是使所有或几乎所有条目无效。在地址转换高速缓存中的每个条目中提供一个或多个翻译模式位。可以根据用于创建高速缓存条目的寻址模式来设置这些转换模式位。在指令中定义一个或多个“提示位”，该指令允许根据翻译模式位的值来指定在无效操作期间选择性地保留地址转换高速缓存中的哪些条目。在替代方案中，可以定义多个指令以保留具有指定寻址模式的地址转换高速缓存中的条目。以这种方式，使用更多的智能来识别地址转换高速缓存中的一些条目在任务或分区切换之后可能是有效的，并且因此可以被保留，而地址转换高速缓存中的其他条目是无效的。

摘要： In a system with multiple execution units, instructions are queued to allow efficient dispatching. One load/store unit (LSU) may have a store instruction pending to a real address and a second LSU may have a load instruction pending to the same real address. An SMT system has an atomic store quad word (SQW) instruction with a data path that is only double wide and the SQW requires two cycles to complete. The SMT system requires a method to prevent between collisions in a store reorder queue (SRQ) STQ. The real address of a load word (LW) one thread is compared to the real addresses in the SRQ of the second thread. If the SQW with a real address matching the real address of the LW has not committed both of its double words, then the LW of the second thread is rejected.
摘要翻译：在具有多个执行单元的系统中，排队等待指令进行高效的调度。一个加载/存储单元（LSU）可以具有等待到实际地址的存储指令，并且第二LSU可以具有等待到同一实际地址的加载指令。 SMT系统具有原子存储四字（SQW）指令，数据路径仅为双倍宽，SQW需要两个周期才能完成。 SMT系统需要一种方法来防止存储重新排序队列（SRQ）STQ中的冲突。一个线程的加载字（LW）的真实地址与第二个线程的SRQ中的实际地址进行比较。如果具有与LW的实际地址匹配的实际地址的SQW没有提交两个双字，则第二个线程的LW被拒绝。
