  • Publication number: 20140365703
    Abstract: An exemplary semiconductor circuit bus system includes: a first bus comprised of distributed buses and having a first transfer rate; a second bus with a second transfer rate higher than the first transfer rate; a transmission node; a bus interface (IF) to connect the transmission node to the first bus; a router which connects the first and second buses; and a reception node connected to the second bus. The bus IF controls the flow rate of data flowing through the transmission routes of the first bus by reference to information about the amounts of transmissible data of the transmission routes. The router allocates the amounts of transmissible data to the transmission routes of the first bus and provides information about the amounts of transmissible data of the transmission routes for the bus IF and also controls the flow rate of the data flowing through the second bus.

  • Publication number: 20140204740
    Abstract: In an NoC bus system, data is transmitted between first and second nodes through a router. The data includes performance-ensuring data which guarantees throughput and/or a permitted time delay. The first node generates packets, each including the data to be transmitted and classification information that indicates the class of that data to be determined according to its required performance, and controls transmission of the packets. The router includes a buffer section configured to store the received packets separately after having classified the packets according to their required performance by reference to the classification information, and a relay controller configured to control transmission of the packets stored in the buffer section at a transmission rate which is equal to or higher than the sum of transmission rates to be guaranteed for every first node associated with the classification information by reference to each piece of the classification information.
