Abstract

The present invention relates to a software module, and, especially, relates to a software module for integration having severe restriction on the available memory amount and the real-time operation, and provides a software module for integration having increased inheritance in software. This is a software module for integration, integrated as a software module within a device to control the device. The software module has a public module for updating a public data value, an intermediate module for converting the data value in a predetermined data format updated in the public module into a data value in a predetermined data format adaptable to a referencing side, and a referencing module for referencing the data value in a predetermined data format converted by the intermediate module. The publication and referencing process can be implemented among the modules.

Claims

1. A software module for integration, integrated as a software module within a device to control the device, comprising

a public module for updating a public data value,

an intermediate module for converting the data value in a predetermined data format updated in the public module into a data value in a predetermined data format adaptable to a referencing side, and

a referencing module for referencing the data value in a predetermined data format converted by the intermediate module,

whereby the publication and referencing process can be implemented among the modules.

2. A software module for integration according to claim 1, wherein the intermediate module comprises a common converting section which receives a referencing request from the referencing module, converts the data value in the predetermined data format updated in the public module into a data value in a predetermined data format designated by the referencing request, and returns the converted data to the referencing module from which the referencing request has been issued.

3. A software module for integration according to claim 1, wherein the intermediate module is embedded as a part of the referencing module, and the intermediate module converts the data value into that of a predetermined data format adaptable to an internal process of the referencing module, upon referencing the data value in the predetermined data format updated in the public module.

4. A software module for integration according to any one of claims 1 to 3, wherein the data value in a predetermined data format updated in the public module is a physical quantity.

5. A software module for integration according to any one of claims 1 to 3, wherein the data value in a predetermined data format updated in the public module is a data of a stored value with LSB information.

6. A software module for integration according to any one of claims 1 to 5, wherein the public module is constituted by using a RAM.
