Abstract
Systems, methods, and computer programs are disclosed for providing power-efficient file system operation to a non-volatile block memory. An exemplary embodiment of a system comprises a non-volatile block memory having a file system, a dynamic random access memory (DRAM), and a system on chip (SoC). The SoC comprises a central processing unit (CPU), one or more non-core processors, a DRAM controller, a data interface coupled to an off-chip processor, and a multi-host storage controller. The CPU allocates a storage buffer in the non-volatile block memory. The multi-host storage controller comprises a virtualized client interface for providing the non-core and off-chip processors with direct read/write file system access using the allocated storage buffer while the CPU and the DRAM are in a low power state.
