Abstract
Methods and systems for operating automotive computing devices are described. In one embodiment, multiple object store pages are maintained in device SRAM that is configured to be battery backed in an event of a power loss. One or more object store pages are periodically flushed to device non-volatile memory to make room for additional object store pages. The frequency of object store page writes is tracked, and object store pages that are least frequently written to are flushed before object store pages that are more frequently written to. In addition, in the event of a power loss, the SRAM is battery backed.
