ABSTRACT:
A multi-core bus termination apparatus includes a protocol analyzer and a plurality of drivers. The protocol analyzer is disposed within a processor core and configured to receive one or more protocol signals, and is configured to indicate whether or not the processor core owns the bus. The plurality of drivers is coupled to the protocol analyzer. Each of the plurality of drivers has one of a corresponding plurality of nodes, and each is configured to control how the one of the corresponding plurality of nodes is driven responsive whether or not the processor core owns the bus. Each of the plurality of drivers has protocol-based multi-core logic. The protocol-based multi-core logic is configured to enable pull-up logic if the processor core owns the bus, and is configured to disable the pull-up logic if the processor core does not own the bus.
