Initialization data memory space allocation system
An initialization data memory space allocation system includes a memory system having a memory space that includes an initialization data bucket that reserves a contiguous subset of the memory space for initialization data. Each initialization engine that is coupled to the memory system is configured during initialization operations to allocate, for that initialization engine, a portion of the contiguous subset of the memory space reserved by the initialization data bucket, and then store initialization data in that portion of the contiguous subset of the memory space reserved by the initialization data bucket. A runtime engine that is coupled to the memory system is configured, during runtime operations, to claim the contiguous subset of the memory space reserved for initialization data by the initialization data bucket for runtime data, and store runtime data in at least a portion of the contiguous subset of the memory space.
