Abstract
A new approach is proposed to support SRAM less bootup of an electronic device. A portion of a cache unit of a processor is utilized as a SRAM to maintain data to be accessed via read and/or write operations for bootup of the electronic device. First, the portion of the cache unit is mapped to a region of a memory, which has not been initialized. The processor reads data from a non-modifiable storage to be used for the bootup process of the electronic device and writes the data into the portion of the cache unit serving as the SRAM. To prevent having to read or write to the uninitialized memory, any read operation to the memory region returns a specific value and any write operation to the memory region is dropped. The processor then accesses the data stored in the portion of the cache unit to bootup the electronic device.
