摘要： Queuing of received transactions that have a resource conflict is disclosed. A first node receives a first transaction from a second node, where the first transaction relates to a resource of the first node. The transaction may be a request relating to a memory line of the first node, for instance. It is determined that a second transaction that relates to this resource of the first node is already being processed by the first node. Therefore, the first transaction is enqueued in a conflict queue within the first node. The queuing may be a linked list, a priority queue, or another type of queue. Once the second transaction has been processed, the first transaction is restarted for processing by the first node. The first transaction is then processed by the first node.

摘要： The temporary storage of a memory line to be stored in a cache while waiting for another memory line to be evicted from the cache is disclosed. A method includes evicting a first memory line currently stored in the cache and storing a second memory line not currently stored in the cache in its place. While the first memory line is being evicted, such as by first being inserted into an eviction queue, the second memory line is temporarily stored in a buffer. The buffer may be a data transfer buffer (DTB). Upon eviction of the first memory line, the second memory line is moved from the buffer into the cache.

摘要： A multiple-stage pipeline for transaction conversion is disclosed. A method is disclosed that converts a transaction into a set of concurrently performable actions. In a first pipeline stage, the transaction is decoded into an internal protocol evaluation (PE) command, such as by utilizing a look-up table (LUT). In a second pipeline stage, an entry within a PE random access memory (RAM) is selected, based on the internal PE command. This may be accomplished by converting the internal PE command into a PE RAM base address and an associated qualifier thereof. In a third pipeline stage, the entry within the PE RAM is converted to the set of concurrently performable actions, such as based on the PE RAM base address and its associate qualifier.

摘要： A hazard queue for a pipeline, such as a multiple-stage pipeline for transaction conversion, is disclosed. A transaction in the pipeline is determined to represent a hazard relative to another transaction, such as by evaluating the transaction against a hazard content-addressable memory (CAM). The hazard CAM can enforce various hazard rules, such as considering a transaction as active if it is referencing a memory line and is currently being processed within the pipeline, and ensuring that only one active transaction with a given coherent memory line is in the pipeline at a single time. In response to determining that a transaction is a hazard, the transaction is routed to a hazard queue, such as at the end of the pipeline. Once the hazard is released, the transaction re-enters the pipeline.

摘要： Information regarding memory access by other nodes within a coherency controller of a node is locally stored. The coherency controller receives a transaction relating a line of local memory of the node. In response to locally determining that the line of the local memory is not being cached by another node and/or has not been modified by another node, the coherency controller processes the transaction without accessing tag directory information regarding the line. A table within the controller may store entries corresponding to local memory sections. Each entry includes a count value tracking a number of lines of the section being cached by other nodes, and a count value tracking a number of lines of the section that have been modified by other nodes. The table may also include flags corresponding to the sections, each flag indicating the validity of the section's contents.

摘要： Non-inline transaction error correction is disclosed. Where a transaction being processed in a pipeline is determined to include a correctable error, it is output, or drained, from the pipeline into an error queue. The pipeline is switched from a normal mode of operation to a correction mode of operation. In the correction mode, a correction command is inserted into and processed within the pipeline to correct the error within the transaction. The pipeline is switched from the correction mode of operation to a restart mode of operation. In the restart mode, the transaction is reprocessed within the pipeline. The pipeline is then switched from the restart mode of operation back to the normal mode of operation.
