Title:
DATA TRANSMISSION DEVICE FOR IN-VEHICLE MULTI-CORE CONTROL AND ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065302
Kind Code:
A1
Abstract:
In order to enable a data set for which synchronicity has been maintained to be transferred between cores in a multi-core system while improving the real-time characteristic of processing by the cores, even when the cores operate asynchronously, the present invention is provided with bank memories B(1) – B(5), and a writing core 601 and reading cores 602-1, 602-2, and 602-3 capable of accessing these bank memories B(1) – (B5). Furthermore, an access control unit 603 assigns only the one writing memory 601 to the bank memories B(1) – B(5) to which writing is being carried out, assigns one or more of the reading cores 602-1, 602-2, and 602-3 to the bank memories B(1) – B(5) from which reading is being carried out, and controls access to the bank memories B(1) – B(5) in an asynchronous manner such that the bank memories B(1) – B(5) to which writing is being carried out and the bank memories B(1) – B(5) from which reading is being carried out are not the same.
