摘要： An apparatus, processor, and method for synchronizing trace data. A processor includes multiple cores, and each core operates at a different local clock frequency. A global clock is distributed to each core, and a timestamp is generated using the global clock and the local clock. The timestamp and a local clock saturation value are included in each trace entry, and the local clock saturation value is equal to the ratio between the local clock and the global clock. The trace entries from separate cores are time-correlated in a post-processing phase based on the timestamp and local clock saturation values.

摘要： In an electronic system that includes a plurality of electronic modules and a plurality of debug circuits, each of which is integrated with one of the plurality of electronic modules, a method for performing debug operations is performed by the plurality of debug circuits. The method includes each of the plurality of debug circuits producing a first cross trigger signal on a communications interface between the plurality of debug circuits, where the first cross trigger signal indicates that a triggering event has not occurred. The method further includes each of the plurality of debug circuits determining whether the triggering event has occurred, and in response to determining that the triggering event has occurred, each of the plurality of debug circuits producing a second cross trigger signal on the communications interface, which indicates that the triggering event has occurred.

摘要： In an embodiment, a system comprises a memory system and a guest interrupt manager. The guest interrupt manager is configured to receive an interrupt message corresponding to an interrupt that is targeted at a guest executable on the system. The guest interrupt manager is configured to record the interrupt in a data structure in the memory system to ensure that the interrupt is delivered to the guest even if the guest is not active in the system at a time that the interrupt message is received.

摘要： A cache memory system includes multiple cache levels arranged in a hierarchical fashion. A data item stored in a higher level cache level is also stored in all lower level caches. The most recent version of a data item is detected during an initial lookup of a higher level cache. The initial lookup of a higher level cache includes a comparison of address bits for the next lower level cache. Thus the most recent version of a data item is able to be detected without additional lookups to the lower level cache.

摘要： A semiconductor memory device according to the invention includes a main memory array comprising a plurality of memory sub-arrays. Each of the memory sub-arrays comprises a plurality of columns and at least one redundant column. Each column of the memory sub-array also includes multiplexing means, coupled to the input and output path of the respective column and an input and output path of a neighboring column. In addition, the redundant column is coupled to the input and output path of a neighboring column. In the event that one of the columns of the memory sub-array is defective, the multiplexing means of each of the columns between the defective column and the redundant column acts to couple the input and output paths of that column to the input and output paths of the neighboring column. With such an arrangement, the defective column is bypassed and a memory device capable of operating without defects is provided.
