Abstract: A method of managing a memory of an apparatus includes maintaining a plurality of lists of identifiers that each has an associated size value, wherein each identifier identifies a corresponding region of the memory that had been allocated for a process but that is currently not required by any of the one or more processes. When a process requests allocation of a region of the memory: one of the lists is identified that has an associated size value suitable for the allocation request; and if that list is not empty, a region of the memory is identified to the process by one of the identifiers that identifier is removed from that list, and, otherwise, a region of the memory is allocated with a size of the identified associated size value and the allocated region of the memory is identified the process.

Abstract: A data processing apparatus includes a processing unit having first and second modes of operation for processing data, including receiving data packets from a sender and sending acknowledgements to the sender, the second mode of operation requires more power than the first mode, and the processing unit switches between the first and second modes of operation based on a processing load; a metric module for determining a metric indicative of the processing load; an acknowledgement module for sending one acknowledgement in respect of n received data packets; and an acknowledgement configuration module for setting n to be a value m greater than a first predetermined value if the metric lies in a predetermined range that includes a value that the metric assumes when the processing unit switches between the first mode of operation and the second mode of operation, and to the first predetermined value otherwise.

Abstract: A method of managing a memory of an apparatus, the apparatus executing one or more processes using the memory. The method comprises maintaining a plurality of lists of identifiers, wherein each list has an associated size value and an associated threshold corresponding to a maximum number of identifiers in that list, wherein each identifier identifies a corresponding region of the memory that had been allocated for a process but that is currently not required by any of the one or more processes, and wherein the size of a region of the memory identified by an identifier of a list equals the size value associated with that list.

Abstract: Redundant storage devices in particular suitable for so-called SSD electronic disks. A data storage system is proposed based on a plurality of redundant physical storage disks in which the read/write commands intended to be sent to the redundant disks are subjected to a transfer function before being sent to at least one of the disks so that the actual commands sent to at least two disks are different. The values returned by the disks that received the commands that had undergone the transfer function are subjected to the inverse transfer function. Thus, a design error in the control module of the disks will be detected, since the control modules of the disks will not be called identically.

Abstract: A datagram flow optimizer apparatus comprises a buffer resource capable of receiving and temporarily storing a plurality of datagrams in respect of a forward path. The apparatus also comprises and a buffer controller arranged to implement, when in use, buffering of received datagrams by the buffer resource until a predetermined threshold number of datagrams has been stored by the buffer resource. The apparatus further comprises an acknowledgement regulator arranged to use the buffer resource to manipulate temporal spacing between acknowledgements of datagrams on a reverse path. The buffer controller is arranged to permit forwarding on the forward path of datagrams stored by the buffer resource in response to the predetermined threshold number of stored datagrams being reached.
