摘要： Methods and apparatus in a computer system are disclosed for providing a memory controller featuring a dedicated bank sequencer for each memory bank in a memory system. Each bank sequencer controls the dispatch of load and store requests to a central controller such that each request sent to the central controller can be served by the associated memory bank at the time that the central controller receives the request. Since every request received by the central controller is valid from a bank timing standpoint, the central controller is free to process the requests from a predetermined priority basis, without concern for bank availability. This significantly improves the design of the memory controller in the processing system.

摘要： A computer system having patrol snoop sequencer that sequences through addresses of cache lines held in a higher level cache, making snoop reads using those addresses to a lower level cache. If a particular cache line held in the higher level cache is not held in the lower level cache, the particular cache line is identified as an eviction candidate in the higher level cache when a new cache line must be loaded into the higher level cache.

摘要： Synchronous dynamic random access memory (SDRAM) method and apparatus are provided for implementing address error detection. Addressing errors are detected on the memory interface independent of data ECC, with reduced memory read access latency and improved processor performance. Addressing errors are detected while allowing differentiation between memory addressing failures that are required to stop the system and memory cell failures that allow continued operation. A predefined pattern is generated for a write burst to the SDRAM. The predefined pattern is dependent on a write address. A bit of the predefined pattern is sequentially stored into the SDRAM on each burst transfer of the write burst to the SDRAM. An expected pattern is generated from a read address for a read burst. The stored predefined pattern is retrieved during a read burst. The retrieved predefined pattern is compared to the generated expected pattern for identifying a type of an addressing error.

摘要： An apparatus and method is disclosed for providing capacity on demand using control to alter latency and/or bandwidth on a signaling bus in a computer system. If additional capacity is required, authorization is requested for additional capacity. If authorized, bandwidth of the signaling bus is increased to provide additional capacity in the computing system. Alternatively, upon authorization, latency of data transmissions over the signaling bus is reduced. In another alternative, upon authorization, memory timings are adjusted to speed up memory fetches and stores.

摘要： The present invention implements a mechanism to decide when it is beneficial to switch from the current virtual input/output mechanism to a different one. The present invention determines which input/output mechanism each virtual machine should use based on the available input/output resources of the virtual machines (with their respective available input/output adapters), the number of virtual machines running and their input/output needs, and the input/output needs of the virtual machine being considered. The present invention also provides a mechanism for virtual machine to seamlessly switch input/output mechanisms. When beneficial, the standard hot-plug mechanism of the virtual machine and the hypervisor is used to first remove the existing input/output mechanism and then add the new input/output mechanism.

摘要： A diagnostic interface architecture for a memory device supports in one aspect one or more dynamically reconfigurable functional interconnects normally utilized in connection with reading data from the memory device and/or writing data to the memory device. The dynamically reconfigurable functional interconnects are capable of being configured to operate in either functional or diagnostic modes, whereby in the diagnostic mode, such interconnects may be used to communicate diagnostic information to support one or more diagnostic operations. The diagnostic interface architecture may also support multiple diagnostic interfaces in a given memory device, with at least one such diagnostic interface being capable of being selectively enabled in response to a failure in another diagnostic interface.
