Japanese Patent JP2023142458
Kind Code:
A
Abstract:
To achieve compatibility that has high real time capability, yet allows executing an existing application program, when updating a control device.SOLUTION: The control device comprises an arithmetic processing device that executes a binary, a memory, a first cache that is provided inside of the arithmetic processing device, an I/O module, a second cache that holds a portion of the data processed by the I/O module, together with address information, and a transfer control unit. The transfer control unit exercises control for transferring the data held in the second cache to the memory with the timing at which the I/O module accesses the second cache, and making the data reflected in the memory, and exercises control for transferring the data held in the first cache to the second cache via the memory with the timing at which the binary executed by the arithmetic processing device accesses the designated address of the I/O module, and making the data reflected in the I/O module.SELECTED DRAWING: Figure 1
