Message conversion and message passthrough between devices and a processor in a multi-panel computing device

A system comprising:

• a first processor disposed within a lid portion of a computing device including a screen, the first processor communicatively coupled to a plurality of input/output (I/O) devices according to a plurality of/O communication protocols via a first number of wires;
• and
• a first memory coupled to the first processor to store first instructions that, when executed by the first processor, cause the first processor to:
• receive, from a first I/O device of the plurality of I/O devices, a first message according to a first I/O communication protocol of the plurality of I/O communication protocols;
• convert the first message to a second message according to a host communication protocol;
• and
• send the second message over a bus containing a second number of wires traversing a hinge movably coupling the lid portion to a base portion of the computing device, wherein the second number of wires is less than the first number of wires.

An apparatus, comprising:

• a first processor;
• a first plurality of pins to support a plurality of input/output (I/O) communication protocols associated with a first plurality of wires to communicatively couple the first processor to a plurality of/O devices disposed in a first portion of a computing device;
• a second plurality of pins to support a host communication protocol associated with a second plurality of wires to communicatively couple the first processor to a second processor in a second portion of the computing device;
• and
• memory coupled to the first processor, the memory to store first instructions that, when executed by the first processor, cause the first processor to:
• receive a first message from a first I/O device of the plurality of I/O devices according to a first I/O communication protocol of the plurality of/O communication protocols;
• convert the first message to a second message based on the host communication protocol;
• and
• send the second message to the second processor via the second plurality of wires, wherein the second plurality of wires includes fewer wires than the first plurality of wires.

One or more machine readable media comprising instructions for execution that when executed by a first processor, cause the first processor to:

• receive, from a first input/output (I/O) device of a plurality of/O devices in a lid portion of a computing device including a screen, a first message based on a first I/O communication protocol of a plurality of/O communication protocols associated with a first plurality of wires to connect the first processor to the plurality of/O devices;
• convert the first message to a second message based on a host communication protocol associated with a second plurality of wires to connect the first processor to a second processor in a base portion of the computing device;
• and
• send the second message over the second plurality of wires to traverse a hinge movably coupling the lid portion and the base portion, wherein the second plurality of wires includes fewer wires than the first plurality of wires.
