A method of declaring and using variables includes; determining whether variables are independent variables or common variables, declaring and storing the independent variables in a plurality of data structures respectively corresponding to the plurality of processors, declaring and storing the common variables in a shared memory area, allowing each one of the plurality of processors to simultaneously use the independent variables in a corresponding one of the plurality of data structures, and allowing only one of the plurality of processors at a time to use the common variables in the shared memory area.

Multi-processor system device and method declaring and using variables

Provided is a method of changing a communication link between source devices and sink devices. The method includes in a first downlink period, broadcasting an uplink period allocation message to the sink devices and passive source devices by an active source device, which establishes a communication link with a primary sink device from among the sink devices; during a first uplink period, broadcasting by a primary passive source device a link set message for establishing a communication link with the primary sink device to all the source devices in the network; during a second downlink period, relaying the link set message to all the sink devices in the network, wherein the link set message is relayed by the active source device; and during a second uplink period, establishing a communication link between the primary sink device and the primary passive source device by the primary sink device.
