A slave node () is slave equipment that operates in accordance with a control frame transmitted from a master node (). The slave node calculates a control frame statistic that is a statistic of one or more control frames transmitted from the master equipment and estimates a master environment value based on the calculated control frame statistic. The slave node measures a slave environment value. The slave node estimates a frequency deviation of a master clock based on the estimated master environment value and estimates a frequency deviation of a slave clock based on the measured slave environment value. The slave node modifies a clock value of the slave clock based on a difference between the frequency deviation of the master clock and the frequency deviation of the slave clock.

Slave equipment, computer readable medium, and embedded system

A CPU module () includes a first bus complying with a first communication protocol, and a second bus complying with a second communication protocol different from the first communication protocol. A conversion setting storage () included in the CPU module () stores information indicating association between a general instruction complying with the first communication protocol and a dedicated instruction complying with the second communication protocol. A protocol converter () included in the CPU module () acquires, when the general instruction is output by instruction output means to a device connected via the second bus, the dedicated instruction associated with the general instruction from the conversion setting storage () and provides the acquired dedicated instruction to the device via the second bus.

Instruction conversion device, method, and program

In an information processing apparatus (), obtaining units such as a first obtaining unit () and a second obtaining unit () obtain general-purpose OS information in a test operation phase in which a real-time application and a plurality of general-purpose applications are executed. The general-purpose OS information is information on use of hardware by each of the plurality of general-purpose applications executed in the test operation phase. A management unit () verifies whether or not a condition to place a restriction on the use of the hardware is satisfied for each general-purpose application based on the general-purpose OS information obtained by the obtaining unit. The management unit (), when the condition is verified as being satisfied, places a restriction on the use of the hardware for an applicable general-purpose application in an actual operation phase in which the real-time application and the plurality of general-purpose applications are executed.
