An electronic control device (1) in which a memory is shared by a plurality of applications is provided with: a region assurance request reception unit (2a) that receives a region assurance request from a region assurance request application; a region determination unit (2b) that, if a region assurance request from the region assurance request application is received, determines whether or not the capacity of an unallocated region of the memory exceeds a request capacity specified by the region assurance request; a region release unit (2c) that releases, as a release region, at least a portion of an unused region among the allocation regions allocated to the region-allocated application, if the capacity of the unallocated region of the memory does not exceed the requested capacity; and a region allocation unit (2d) that allocates the total capacity of at least a part of the capacity of the unallocated region and the capacity of the released region as the allocation region corresponding to the region assurance request.
由多个应用共享存储器的电子控制装置(1)具备:区域确保请求接受部(2a),接受来自区域确保请求应用的区域确保请求;区域判定部(2b),若接受了来自区域确保请求应用的区域确保请求,则判定存储器的未分配区域的容量是否超过由区域确保请求指定的请求容量;区域释放部(2c),在存储器的未分配区域的容量不超过上述请求容量的情况下,将已经分配给区域分配完毕应用的分配区域中的未使用区域的至少一部分作为释放区域进行释放;以及区域分配部(2d),将未分配区域的容量的至少一部分与释放区域的容量的合计容量分配为与区域确保请求对应的上述分配区域。
