摘要： A method of operating a bus interconnect coupled to bus masters and bus slaves is provided. The method includes receiving a request from a bus master to perform a bus transaction associated with a transaction ID with a bus slave of the plurality of bus slaves, the bus transaction being a first type of bus transaction. The method further includes performing the transaction if a resource allocation parameter allocated to the bus master meets a first threshold. The method further includes if the resource allocation parameter does not meet the first threshold, performing the data transaction only if the transaction meets a condition of a set of at least one condition, wherein a condition of the set of at least one condition includes that the transaction ID of the transaction is not a transaction ID of any outstanding bus transaction of the first type requested by the bus master.

摘要： A method and system for controlling transmission and execution of commands in an integrated circuit (IC) device provide transmission of commands and acknowledgements in an order of their priorities. Priority levels of the commands and acknowledgements are defined based on pre-assigned levels of precedence of the respective master and slave devices. In one application, the invention is used to increase performance of IC devices employing an Advanced eXtensible Interface (AXI).

摘要： An apparatus and method for sharing I/O devices. The apparatus has a first plurality of I/O ports, a second I/O port, and core logic. The first plurality is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality routes transactions between the operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint requests/completes transactions for each of the plurality of operating system domains. The core logic is coupled to the first plurality of I/O ports and the second I/O port. The core logic routes the transactions between the first plurality of I/O ports and the second I/O port and associates each of the transactions with a corresponding one of the plurality of operating system domains (OSDs) by encapsulating an OS domain header within a transaction layer packet.

摘要： An apparatus and method is provided for allowing I/O devices to be shared and/or partitioned among a plurality of processing complexes within the load/store fabric of each of the processing complexes without requiring modification to the operating system or driver software of the processing complexes. The apparatus and method includes a switch for selectively coupling each of the processing complexes to one or more shared I/O devices. The apparatus and method further includes placing information within packets transmitted between the switch and the I/O devices to identify which of the processing complexes the packets are associated with. The invention further includes an apparatus and method within the shared I/O devices to allow the shared I/O devices to service each of the processing complexes independently.

摘要： An apparatus and method are provided that enable I/O devices to be shared among multiple operating system domains. The apparatus includes a first plurality of I/O ports, a second I/O port, and a plurality of port initialization logic elements. The first plurality of I/O ports is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality of I/O ports routes transactions between the plurality of operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint is configured to request/complete the transactions for each of the plurality of operating system domains. One of the plurality of port initialization logic elements is coupled to the second I/O port and remaining ones of the plurality of port initialization logic elements are each coupled to a corresponding one of the first plurality of I/O ports. The plurality of port initialization logic elements is configured to initialize corresponding links between each of the plurality of operating system domains and the switching apparatus, and between the first shared input/output endpoint and the switching apparatus, to support the transactions, where each of the plurality of port initialization logic elements automatically configures a corresponding polarity for each of the first plurality of I/O ports and the second I/O port, and where the corresponding polarity is in a default polarity prior to being configured.
