The invention discloses an information
display device based on dual processor cooperation, which comprises two display subsystems, a cooperation unit and a sharing storage unit, wherein the two display subsystems are respectively connected to the cooperation unit through the respective communication buses of the two display subsystems and are connected to the sharing storage unit through the respective address / data buses of the two display subsystems; the cooperation unit is connected to the sharing storage unit by a
control bus; the cooperation unit is used for performing the
cooperative work,
data exchange and
data sharing of the two display subsystems; the cooperation unit is communicated with processors of the two display subsystems through a protocol;
information type and
data format transferred between the cooperation unit and the processors are defined in the communication protocol; the cooperation unit is used for specifically managing a distributed
processing task in the whole
system, including the activation, scheduling and tracking of each process and the communication and synchronization among processes related to the distributed
processing task. The sharing storage unit is used for storing various information and data which are used by the two display subsystems; and under the control of the cooperation unit, the subsystems access the RAM (random-access memory)in the sharing storage unit in sequence through the respective address / data buses of the subsystems. By using the device provided by the invention, the running property of dual processor
system can be efficiently promoted, the executing efficiency of concurrent process in the
system can be improved, the access conflict of sharing resource is avoided, and the
processing speed of complex task is increased.
