Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/009741
Kind Code:
A1
Abstract:
Provided is an electronic control device with which it is possible to raise the efficiency of data delivery between applications in time-synchronized design. This electronic control device comprises: a processor including a plurality of cores operating on different cycles, said cores executing a plurality of processes; and a memory including a plurality of memory areas that can be individually accessed for each of the plurality of cores that execute a plurality of processes. The electronic control device changes, in accordance with the progress of the processes, the memory areas accessible by a preceding process that performs data writing and a subsequent process that performs data reading. The processor searches for a writable memory area into which the latest result of processing has not been written yet and which is not in the middle of a read, reserves a new memory area when no writable memory areas exist, and sets the new memory area as the destination to which the result of processing is written, whereby the result of processing is delivered from the preceding process to the subsequent process.
