  • Publication number: 20140035633
    Abstract: On a transmission path connecting a first semiconductor integrated circuit that is started by a system management apparatus and a second semiconductor integrated circuit that is not started by the system management apparatus, when connection of the first semiconductor integrated circuit to the second semiconductor integrated circuit is detected, after being turned to a first signal state for detecting a valid lane, each lane on the transmission path is turned to a second signal state corresponding to each bit of initial setting code. In the second semiconductor integrated circuit, the first and second signal states are detected for each lane of the transmission path. Based on the detected signal state, after detecting the first signal state, the second signal state is detected and each bit value of the initial setting code is decoded. Based on the decoded initial setting code, an initialization process is executed.

  • Publication number: 20130343382
    Abstract: A relay device includes a first determining unit, a first sending unit, a receiving unit, a setting unit, a second determining unit, and a second sending unit. When the first determining unit determines that the relay device is a parent node, the first sending unit sends a set value stored in a storing unit to all the other relay devices to which the relay device is connected. When the first determining unit determines that the relay device is not the parent node, the receiving unit receives the set value. The setting unit sets the set value received by the receiving unit in the storing unit. When the second determining unit determines that the received set value has not been sent to the other relay devices, the second sending unit sends the received set value to the other relay devices to which the relay device is connected.

  • Patent number: 8499125
    Abstract: To prevent a decrease in performance of controlling a snoop tag. A queue is stored with REPLACE target WAY information and an index as an entry associated with a REPLACE request received from a processor, the index stored in the queue is compared with an index of a subsequent READ request, and, as a result of the comparison, a process based on the index-coincident READ request is executed with respect to the snoop tag corresponding to a content of a cache memory of the processor. Further, the REPLACE target WAY information of the READ request is replaced with the WAY information in the index-coincident entry within the queue.

  • Patent number: 8181064
    Abstract: A northbridge, when detecting a synchronization break of a redundant CPU, stops the operation of an abnormal CPU bus where an error has occurred and the firmware in a firmware hub instructs the northbridge to inhibit an external instruction. In addition, the firmware saves the inside information of a normal CPU connected to a normal CPU bus and cache data on a memory and the northbridge issues reset to all CPUs in the home system board. The firmware then restores the inside information of the CPU saved on the memory to all CPUs and instructs the northbridge to cancel the inhibition of the external instruction.

  • Patent number: 8090912
    Abstract: A request issued by the CPU is output from the local arbiter by way of the CPU bus and the CPU-issued request queue. The cache replacement request loop-back circuit determines at the loop-back determination circuit whether the outputted request is a cache replacement request or not. A request other than a cache replacement request is output onto the local bus. A cache replacement request is output to the selector and sent to the request handling section when there is no valid request on the global bus.

  • Patent number: 7873789
    Abstract: In a system controller including a CPU-issued request queue having a circuit that processes plural requests having identical addresses not to be inputted to the CPU-issued request queue, a latest request other than a cache replace request is retained by an input-request retaining section. Consequently, even if an address of an issued request for cache replace request matches an address of a request retained by the CPU-issued request queue, the issued request for the cache replace request is not retried but is queued in the CPU-issued request queue when the address of the issued request for the cache replace request does not match the entire address retained by the input-request retaining section.
