Patent attributes
A multi-master hybrid bus apparatus is provided. The multi-master hybrid bus apparatus includes a hybrid bus bridge circuit configured to couple multiple master circuits with one or more slave circuits via heterogeneous communication buses. In examples discussed herein, the multiple master circuits can correspond to multiple physically separated master circuits or multiple bus ports provided in a single master circuit. In a non-limiting example, the hybrid bus bridge circuit is coupled to the multiple master circuits via multiple radio frequency front-end (RFFE) buses and to the slave circuits via at least one single-wire bus (SuBUS) consisting of a single wire. By bridging the multiple master circuits to the slave circuits based on a single hybrid bus bridge circuit, it may be possible to enable flexible heterogeneous bus deployment in an electronic device (e.g., a smartphone) with reduced cost and/or footprint.
