摘要： Microprocessor that includes a mechanism for detecting soft errors. The processor includes an instruction fetch unit for fetching an instruction and an instruction decoder for decoding the instruction. The mechanism for detecting soft errors includes duplication hardware for duplicating the instruction and comparison hardware. The processor further includes a first execution unit for executing the instruction in a first execution cycle and the duplicated instruction in a second execution cycle. The comparison hardware compares the results of the first execution cycle and the results of the second execution cycle. The comparison hardware can include an exception unit for generating an exception (e.g., raising a fault) when the results are not the same. The processor also includes a commit unit for committing one of the results when the results are the same.

摘要： A processor that includes an in-order execution architecture for executing at least two instructions per cycle (e.g., 2n instructions are processed per cycle, where n is an integer greater than or equal to one) and at least two symmetric execution units. The processor includes an instruction fetch unit for fetching n instructions (where n is an integer greater than or equal to one) and an instruction decoder for decoding the n instruction. The error detection mechanism includes duplication hardware for duplicating the n instructions into a first bundle of n instructions and a second bundle of n instructions. A first execution unit for executing the first bundle of instructions in a first execution cycle, and a second symmetric execution unit for executing the second bundle of instructions in the first execution cycle are provided. The error detection mechanism also includes comparison hardware for comparing the results of the first execution unit and the results of the second execution unit. The comparison hardware can have an exception unit for generating an exception (e.g., raising a fault) when the results are not the same. A commit unit is provided for committing one of the results when the results are the same.

摘要： In an embodiment, a processor includes multiple tiles, each including a core and a tile cache hierarchy. This tile cache hierarchy includes a first level cache, a mid-level cache (MLC) and a last level cache (LLC), and each of these caches is private to the tile. A controller coupled to the tiles includes a cache power control logic to receive utilization information regarding the core and the tile cache hierarchy of a tile and to cause the LLC of the tile to be independently power gated, based at least in part on this information. Other embodiments are described and claimed.

摘要： A dynamic reconfiguration to include on-line addition, deletion, and replacement of individual modules of to support dynamic partitioning of a system, interconnect (link) reconfiguration, memory RAS to allow migration and mirroring without OS intervention, dynamic memory reinterleaving, CPU and socket migration, and support for global shared memory across partitions is described. To facilitate the on-line addition or deletion, the firmware is able to quiesce and de-quiesce the domain of interest so that many system resources, such as routing tables and address decoders, can be updated in what essentially appears to be an atomic operation to the software layer above the firmware.

摘要： Systems, methodologies, media, and other embodiments associated with mitigating the effects of context switch cache and TLB misses are described. One exemplary system embodiment includes a processor configured to run a multiprocessing, virtual memory operating system. The processor may be operably connected to a memory and may include a cache and a translation lookaside buffer (TLB) configured to store TLB entries. The exemplary system may include a context control logic configured to selectively copy data from the TLB to the data store for a first process being swapped out of the processor and to selectively copy data from the data store to the TLB for a second process being swapped into to the processor.
