Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/178202
Kind Code:
A1
Abstract:
The objective of the present invention is to increase reliability in an electronic control device when speculative execution is performed, by reducing the risk of erroneous control by the electronic control device, said erroneous control being due to speculative execution failures (such as failures to predict a future state or failure to complete a control calculation due to the execution of an advanced control calculation) which are generated when speculative execution is performed using limited hardware resources in an electronic control device having a control period restriction. Therefore, this electronic control device, which performs a calculation in accordance with one or more external inputs, and outputs a calculation result by a prescribed time, has one or more first calculation units that perform a calculation using a current input, and one or more second calculation units that perform a calculation using a prior input that been input at a point in time prior to the current input.
