A non-transitory computer-readable recording medium storing an acceleration test program for causing a computer to execute a process, the process includes selecting a cooperation application that operates in cooperation with a test target application that is a target application of an acceleration test by accelerating an operation of an application, determining an acceleration degree of an operation in an acceleration mode in which an operation of an application is accelerated in comparison to a normal mode, and disabling an acceleration of an operation of a non-cooperation application that does not cooperate with the test target application during an acceleration of operations of the test target application and the cooperation application based on the acceleration degree.

A control apparatus that causes data in a first storage unit to be written in a second storage unit, with power supplied from a sub power supply, when supply of power from a main power supply is discontinued, the control apparatus includes a remaining feed duration obtaining unit that obtains remaining feed duration during which the sub power supply can supply the power; and a retry count setting unit that sets a maximum retry count for writing the data from the first storage unit to the second storage unit, based on the remaining feed duration obtained by the remaining feed duration obtaining unit, when an error occurs while the data is being written.

Control apparatus, computer-readable storage medium, and information processing apparatus

A data transmission system includes a plurality of signal lines, a signal line determination unit, and a data transmission unit. The plurality of signal lines transmit data transmitted from a transmission-side device to a reception-side device. The signal line determination unit determines which signal line among the signal lines is used to transmit reception adjustment data to the reception-side device. The data transmission unit uses the signal line determined by the signal line determination unit to transmit the reception adjustment data to the reception-side device and uses another signal line to transmit transmission data to the reception-side device.

Each of (n&#x2212;1) 2-bit checking units, where n is an integer larger than or equal to 4, receives n-bit redundant encoded data generated from 1-bit input data, and outputs 2-bit check data based on a result of comparison between bits of the encoded data, combinations of the bits differing in each comparison. An all-bit checking unit outputs all-bit check data based on exclusive ORs of all-bit of the encoded data. An error detecting unit detects errors in the encoded data on the basis of the (n&#x2212;1) sets of 2-bit check data and the all-bit check data, and outputs the input data on the basis of the result of error detection.

Semiconductor device, information processing apparatus, and method of detecting error

A DMA apparatus which reads data corresponding to a descriptor from memory, and a dividing unit in a descriptor management device divides one descriptor into a plurality of sub-descriptors. A plurality of DMA controllers produce a plurality of reading requests for reading data corresponding to the plurality of sub-descriptors from the memory. A memory controller reads the corresponding data from the memory according to the plurality of reading requests.
