| 1. Control apparatus for a powertrain system comprising an internal combustion engine and a pair of electrical machines each
operably coupled to a two-mode compound-split electro-mechanical transmission, comprising:
a first control device comprising a system controller and first and second motor control processors;
the system controller operable to communicate with the first and second motor control processors via a first high speed communications
bus, a second high speed communications bus, and, first and second serial peripheral interface buses; and,
the first and second motor control processors operable to control flow of electrical power between the pair of electrical
machines and an electrical energy storage device, based upon input from the system controller.
