SHARING BUS PORT BY MULTIPLE BUS HOSTS

摘要

A system for sharing a bus port includes a first bus host, a second bus host, a multiplexer configured to select either the first bus host or the second bus host to connect to a bus port, and a port detector configured to detect whether a peripheral is connected or disconnect to the bus port. The first bus host is configured to: determine, in response detecting a peripheral connected to the bus port, which one of the first bus host or the second bus host the peripheral is dedicated to, and control, in response to the port detector determining that the peripheral is dedicated to the second bus host, the multiplexer to select the second bus host to connect to the bus port.

1. A system for sharing a bus port, comprising:
a first bus host; a second bus host; a selector (e.g. multiplexer) configured to select either the first bus host or the second bus host to connect to a bus port; and a port detector configured to detect whether a peripheral is connected to the bus port; the first bus host being configured to:
determine, in response to the port detector detecting a peripheral connected to the bus port, which one of the first bus host or the second bus host the peripheral is dedicated to, andcontrol, in response to determining that the peripheral is dedicated to the second bus host, the multiplexer to select the second bus host to connect to the bus port.
