Abstract: A hierarchical wearable processing unit (HWPU) (102) for WPUs (100) is described. According to an implementation of the present subject matter, the HWPU (102) may include a plurality of hierarchies (106). Each hierarchy (106) from amongst the plurality of hierarchies (106) is determined for a particular performance and power consumption. Further, the HWPU (102) may include a plurality of hosts (104). One or more hosts (104) from amongst the plurality of hosts (104) are associated with each of the plurality of hierarchies (106) based on the particular performance and power consumption of each of the hierarchies (106). Furthermore, the HWPU (102) may include a control unit (118) to configure each of the plurality of hierarchies (106) with functionalities based on allocation of dedicated hardware resources.

Abstract: Described herein is a multi-host computing system (100) having multiple host processors running different operating systems. In one implementation, a method of playing audio streams received from a plurality of hosts of a multi-host computing system (100), the method comprising receiving a second audio stream from a second host, and changing audio stream parameters associated with the second audio stream from second host to match the corresponding parameter values associated with a first audio stream received from a first host to generate an updated second audio stream. The method further comprises mixing the updated second audio stream with the first audio stream to generate a combined audio stream, and playing the combined audio stream using at least one audio codec (104) of the multi-host computing system (100).
