Abstract:
A semiconductor device includes an operation resource which performs a plurality of ECU functions, a peripheral resource which is shared by the plurality of ECU functions and a control mechanism which controls a period in which one of the ECU functions uses the peripheral resource. The control mechanism calculates, based on a budget value which is given in advance and is a performance allocation, a use prohibition period in which the one of the ECU functions is prohibited from using the peripheral resource within the predetermined unit time.
