摘要： A processor issues a command to a memory through an electrical memory link and performs a process according to the command through the electrical memory link. The processor issues a routing command to an optical circuit switch (OCS) through an OCS control line. In response to the routing command, the OCS establishes a routing of an optical memory link from the processor to the BDM. In response to the establishment of the optical memory link from the processor to the BDM, the processor (or a BDM (internal/dedicated) controller) switches from performing the process through the electrical memory link to performing a process through the optical memory link (continuously without an interruption between the successive processes). Corresponding systems are also disclosed herein.

摘要： A memory controller is provided for accessing shared memory objects by read and write requests made to a memory. The memory controller includes a list for registering address locations of the shared objects in the memory, and having slots for a lock bit. The memory controller includes a read wait queue and a write wait queue for selectively inputting, outputting, holding, and purging requests. The memory controller includes a read initiated queue and a write initiated queue for selectively inputting and purging requests transferred from the read wait queue and the write wait queue, respectively, upon memory access initiation and completion. The memory controller includes a controller for controlling the wait queues using policies by determining which requests to output, hold, and purge, based on a list entry, a lock bit and TTL information set to each request upon a hold being applied thereto and decremented in each cycle.

摘要： Embodiments include providing content requested by a user via an access point capable of wireless communication. Aspects include receiving the content provided by the management server and storing the content provided by the management server into a volatile memory provided in the wireless communication apparatus. Aspects also include storing difference data into a nonvolatile memory if it is requested to change the content stored in the volatile memory and monitoring a state of communication connection with the access point and whether or not a packet giving an instruction to hold the content has been received. Aspects further include deleting the content stored in the volatile memory if communication with the access point is disconnected or if the packet is unreceived.

摘要： A system including multiple nodes performing radio communication, wherein each node stores routing information, uses it to determine a transmission path, and performs cut-through transmission by transmitting and receiving packets to and from a node on the determined path through transmission and reception radio waves given a directivity by controlling their phases. In the system, time synchronization and transmission and reception of packet communication records are performed during a certain time period by carrying out the cut-through transmission while controlling phases of the radio waves so that all of the nodes form one or more closed loops. The node transmits and receives packets in accordance with routing information and a time frame assigned to each of the nodes as a time when each node is allowed to transmit and receive a packet, updates the routing information, and shares it with each node.
