<p>PURPOSE:To improve communication efficiency even in the data communication of a large amount of data or in that of a small amount of and non-periodical data, by providing first and second CPU parts, memory parts, I/O control parts, communication control parts, interruption control parts, serial/parallel conversion parts, and selection parts. CONSTITUTION:The first and second CPU parts 1 and 9 set a first serial/parallel conversion part 6 and a third serial/parallel conversion part 14 for low speed data and set a second serial/parallel conversion part 7 and a fourth serial/ parallel conversion part 15 for high speed data. And in the communication of the small amount of and the non-periodical data, the first and third serial/ parallel conversion parts 6 and 14 are selected, and in the communication of the large amount of or accumulative non-periodical data, the second and fourth conversion parts are selected by using the memory part. Also, in the communication of periodical data, the first and third serial/parallel conversion parts 6 and 14 or the second and fourth serial/parallel conversion parts 7 and 15 are selected according to the kind of data.</p> |
