| 20080294803 | METHOD AND SYSTEM FOR FULL-DUPLEX MESOCHRONOUS COMMUNICATIONS AND CORRESPONDING COMPUTER PROGRAM PRODUCT - Data transport is provided in a communication network such as a Network-on-Chip arrangement via full-duplex mesochronous links between routers. Request signals and response signals are exchanged between these routers acting alternatively as an initiator and a target operating in respective clock domains at opposite ends of respective full-duplex mesochronous links. The request initiator flow control signals are monitored at the target end of the link while the response target flow control signals are monitored at the initiator end of the link. The monitoring action involves ascertaining if a request has been granted at the initiator end of the link and if a response has been granted at the target end of said link thus correspondingly managing the data flow over the link. | 11-27-2008 |
| 20090049212 | METHOD AND SYSTEMS FOR MESOCHRONOUS COMMUNICATIONS IN MULTIPLE CLOCK DOMAINS AND CORRESPONDING COMPUTER PROGRAM PRODUCT - Full-duplex communication over a communication link between an initiator operating with an initiator clock and a target operating with a target clock involves, in communication from the initiator to the target: storing data from the initiator in a first FIFO memory with the initiator clock, reading data from the initiator stored in the first FIFO memory, wherein reading is with the target clock transmitting the data read from the first FIFO memory over a first mesochronous link, and storing the data transmitted over the first mesochronous link in a buffer whereby the data are made available to the target. Communication from the target to the initiator includes: transmitting data from the target over a second mesochronous link, and storing the data transmitted over the second mesochronous link in a second FIFO memory, wherein storing is with the target clock, whereby the data are made available to the initiator for reading from the second FIFO memory with the initiator clock signal. | 02-19-2009 |
| 20100080229 | METHOD OF EXCHANGING INFORMATION IN A COMMUNICATION NETWORK, CORRESPONDING COMMUNICATION NETWORK AND COMPUTER PROGRAM PRODUCT - A method of performing transactions in a communication network in which is exchanged between Intellectual Property (IP) cores has information transported in packets which include a header for transporting control information and one or more payloads transporting content. A versatile packet format is used which is adapted to transport different traffic patterns generated by the IP cores using different protocols for simple interoperability between the IP cores and also providing configurability of the granularity arbitration process to correct crossing the routers in the communication network. | 04-01-2010 |
| 20100281144 | CONTROL DEVICE FOR A SYSTEM-ON-CHIP AND CORRESPONDING METHOD - A system such as a “System-on-Chip” includes an interconnection network, a set of initiator modules for transmitting data towards the interconnection network and at least one communication arbiter for deciding, as a function of a set of configuration values, which transmissions of the initiator modules have access to the interconnection network. At least one configuration value is associated with each initiator module. A control device coupled to at least one of the initiator modules detects a communication status associated with the transmissions of the coupled initiator and generates a communication status signal whose value is representative of such status, determines a filtered value representative of a series of the values of the communication status signal, and selectively varies one of the configuration values as a function of the filtered value. | 11-04-2010 |
| 20110131189 | METHOD AND DEVICE FOR MANAGING QUEUES, AND CORRESPONDING COMPUTER PROGRAM PRODUCT - A method for managing a queue, such as for example a FIFO queue, and executing a look-ahead function on the data contained in the queue includes associating to the data in the queue respective state variables (C | 06-02-2011 |
| 20110289253 | INTERCONNECTION METHOD AND DEVICE, FOR EXAMPLE FOR SYSTEMS-ON-CHIP - Transactions of the request/response type between a first circuit module and a second circuit module operating with incompatible protocols or interfaces envisage organizing a queue of memory locations for storing transaction information items and transaction identifiers associated to said transactions and implementing the transactions via operations of reading/writing of the locations in the queue, mapping on the transaction identifiers information for management of the queue. | 11-24-2011 |
| 20120008620 | CONNECTION ARRANGEMENT - A plurality of inputs are configured to receive circuit switched traffic from a plurality of initiators. A plurality of outputs are configured to output said traffic to a network on chip. Each output is associated with a different quality of service traffic. A traffic controller directs the received circuit switched traffic to respective ones of the outputs in dependence on a quality of service associated with the traffic. | 01-12-2012 |
| 20120079148 | REORDERING ARRANGEMENT - An embodiment of a network-on-chip is provided. The network-on-chip includes a plurality of sources of requests and a plurality of destinations for requests. The plurality of destinations are configured to provide respective responses to respective requests. The network-on-chip further includes an interconnect for routing said requests and respective responses to said requests to and from the plurality of sources and at least one transaction reordering arrangement. The transaction reordering arrangement is configured to reorder said responses such that said responses are provided to a respective source in an order which corresponds to an order in which the requests are issued by said respective source. A respective transaction reordering arrangement is associated with a respective source. | 03-29-2012 |
| 20120079154 | TRANSACTION REORDERING ARRANGEMENT - An embodiment of a transaction reordering arrangement is provided. The transaction reordering arrangement includes a queue into which respective responses to requests are writable and a controller configured to control a position in said queue to which said respective responses to said requests are written. The position is controlled such that the responses are read out of said queue in an order which corresponds to an order in which the requests are issued. | 03-29-2012 |
