Abstract
A method of improving meta-channel communications over a secure digital (SD) bus between an SD host and an SD client is described. The method includes accessing, during a current data transfer over data lines of the SD bus, a first direct memory access (DMA) metadata and a second DMA metadata over a command (CMD) line of the SD bus using an enhanced SD direct command. The method also includes establishing, prior to a next data transfer over the data lines of the SD bus, a DMA configuration for the next data transfer based on the first DMA metadata and the second DMA metadata. The method further includes communicating the next data transfer over the data lines of the SD bus according to the DMA configuration.
