Abstract
A Dynamic Storage Subsystem Morphing (DSSM) mechanism (40) is connected to a plurality of storage subsystem resources, which reserve some storage area each non-donor ECU (12), ready for a “slot-down/up” access by a respective non-donor ECU having a storage subsystem (24) breakdown. The slot-down process enables the use of a high physical address range by the non-donor processor provided with addressing capabilities sufficient only for addressing lower ranges.
Claims13
A method for operating an embedded system covering a plurality of technical applications, the operative functions of which are performed with a respective plurality of application-specific Electronic Control Units (ECU) (10, 12, 14, 16, 18), each ECU having separate need of resources regarding at least processing and storage subsystem, characterized by the steps of:
- a) operating a preselected one of said ECUs as a “donor” ECU (18) being provided with predefined storage subsystem resources, and
- b) in case of a breakdown of a storage subsystem and/or processing subsystem of an “non-donor” ECU (12) donating respective predefined resources to said breakdown ECU (12).
