Abstract: The present invention involves hardware multiplexed memory for unidirectional data transfer circuits, systems and methods. The invention is useful for gathering data at a primary processor and efficiently transferring that data to a secondary processor using Quad Serial Peripheral Interface (QSPI) protocol. The hardware multiplexed memory circuit may include two 6-channel 2-1 multiplexers and two QSPI random access memories interfacing between the two processors. The invention has numerous embedded system applications including, e.g., Internet of Things (IoT) trail cam systems and IoT weather monitors.
