    摘要: Provided are a method and apparatus for controlling a shared memory, and a method of accessing the shared memory. The apparatus includes a processing unit configured to process an application program, a user program unit configured to execute a program written by a user based on the application program of the processing unit, a shared memory unit connected to each of the processing unit and the user program unit through a system bus and configured to store data interchanged between the processing unit and the user program unit, and a control unit configured to relay a control signal indicating whether the system bus, by which the data is interchanged between the processing unit and the user program unit, is occupied, and control connection of each of the processing unit and the user program unit with the system bus in response to the control signal. In the apparatus, the processing unit and the user program unit can easily interchange a large amount of messages through the shared memory unit having an abundant memory space.

    摘要: A low-power method for media access control on a semi-linear sensor network with multiple sensor nodes, includes: sensing a channel after waking up from a sleep mode by an arbitrary transmission sensor node that has obtained data; and generating a long preamble including a number of element preambles and sending to a destination sensor node after said channel sensing. This method further includes: sending said data to said destination sensor node after completion of transmission of said long preamble; and identifying duty cycle information of said destination sensor node after completion of transmission of said data and adjusting the number of said element preambles according to said duty cycle information.
