摘要： In a computer on the transmission side, an NW driver, which is recognized, by the OS, as an NIC driver, stores data to be transmitted and a destination SPA into a memory, and outputs a transaction layer packet (TLP), which has been generated by a first computer, to a PCIe switch. A first NIC logic of the PCIe switch of the PCIe switch corresponding to the first computer on the transmission side adds a system port address (SPA) to the TLP transferred from the first computer, and transfers the data of the TLP to a port associated with a second NIC logic and having an address indicated by the SPA (destination SPA). The second NIC logic having received the data writes the receive data into a memory of a second computer, on the reception side, which is connected to another PCIe switch where the second NIC logic exists.

摘要： A semiconductor integrated circuit is provided whose area overhead due to provision of test points is reduced together with the test time period. In a semiconductor integrated circuit having a plurality of observation points in a tested circuit, the plurality of observation points are divided into a preset number of groups. The semiconductor integrated circuit contains at least one compressing circuit to reduce the number of bits of a multi-bit signal and to output the result (a signal of less bits) to an observable element such as an external output element or a flip-flop with a scan function. The semiconductor integrated circuit also has at least two scan chains each of which is made up with a plurality of flip-flop circuits working as shift registers. Further, the two scan chains are interconnected with a single input terminal.

摘要： The present invention eliminates the shortage of bus numbers in routing control using PCIe switches. A system port address (SPA) is associated with a destination bus number and is assigned to a port (external port) connected to a server and a device. When packets sent from the server or the device are received at the external port, the system port address (SPA) corresponding to the destination bus number having the packets is determined, and the SPA is added to the packets as a label. This SPA is used to route the packets sent between ports (internal ports) that connect switches. When the packets arrive at the external port to which the target server or device is connected, the destination bus number having packets is used to send the packets to the server or device connected to the external port.
