Abstract
A new serial bus interface module that enables constrained sensor systems to better match flash-based storage devices' (SD card) read and write performance. The serial bus interface module augments existing flash-based storage with non-volatile random-access memory to form a hybrid storage system using the most popularly used master-slave bus architecture. Together with PSC-like features, the serial bus interface module not only enables slave-to-slave transfer (therefore eliminating the double-transaction problem) but also reads caching (one source to multi-sink) and buffering while flushing. These transaction types enable multi-sector write for significantly faster speed and lower energy overhead, while the use of non-volatile memory for metadata caching means low risk of file-system corruption in the event of power failure. The serial bus interface also enables the direct data transfer from sensors to storage or communication modules without requiring the microprocessor's intervention.
