摘要： Provided is a backup method including a step (S1) of reading a log which is a data update difference, and identifying a data storage area (page) of backup data, a step (S2) of determining high/low reusability of the identified data storage area, a step (S3) of storing a log corresponding to a data storage area determined to be low in reusability in a log storage area preset on a memory, and a step (S4) of applying a log corresponding to a data storage area determined to be high in reusability to the identified data storage area in a cache area set on the memory, and updating the data storage area. Thus, by further reducing the number of I/O times in an external storage system of a standby system which backs up data by log transfer, it is possible to reduce introduction costs of a backup system and its normal-time operation's costs at normal times.

摘要： It is a task of the invention to make it possible to calculate a control target value of one actuator or control target values of a plurality of actuators regarding engine control at a high speed through the use of a multicore processor. With a view to accomplishing this task, a plurality of lattice points that are arranged on a two-dimensional orthogonal coordinate system having axes representing a first operating condition and a second operating condition respectively are associated respectively with at least one or some of a plurality of cores that are arranged in a latticed manner on the multicore processor on one-on-one level on a same line as on the two-dimensional orthogonal coordinate system, and a calculation program for calculating an optimal control value at the associated lattice point or calculation programs for calculating optimal control values at the associated lattice points are allocated respectively to at least one or some of the plurality of the cores. In addition, each of the cores with which the lattice points are associated respectively is programmed, in a case where an operation area on the two-dimensional orthogonal coordinate system to which a current operating point belongs is an area that is defined by the lattice point associated with each of the cores itself, to transmit, to an interpolation calculation core, an optimal control value at the relevant lattice point that is calculated by each of the cores itself. The interpolation calculation core is programmed to perform an interpolation calculation of an optimal control value at the current operating point using optimal control values at all the lattice points that define the operation area on the two-dimensional orthogonal coordinate system to which the current operating point belongs. In addition, the multicore processor outputs the optimal control value at the current operating point, which is obtained from the interpolation calculation core, as a control target value of each of the actuators.

摘要： A method for estimating steady state values of engine operating characteristics is provided so that engine control can later be based on the estimated values. An amount of change in a specific engine characteristic (for which the steady state values are to be estimated) is set as a product of an unknown value and a dimensionless known value for predetermined times from when a specific engine control parameter is changed. A value of the specific engine characteristic at a given time is calculated as a sum of the products at the given time, with the products respectively corresponding to plural prior changes in the specific engine control parameter. Unknown values are calculated multiple times based on values of the specific engine characteristic measured in a conformance test, and the steady state values of the specific engine characteristic are estimated.
