    • In a multi-processor system, the semaphore device comprises a latch associated by software or hardware to a non-shareable resource. The output of the latch is connected to the bus for the re-reading of the semaphore by the processors. The output of the latch is also connected to an input of a multiplexer connected by its other input to the write bus of the semaphore. The control field output of the latch is connected to an AND gate receiving, at its other input, the control bit of the bus and conditioning, by its output, the writing of the latch. The task seeking to appropriate the semaphore tries to write its unique identifier in the latch with the control field at >. It then re-reads the semaphore register. Equality between the value re-read and the value written means that the task has succeeded in appropriating the resource. The source is released by the writing of the control field at >.
    • 在多处理器系统中,信号量装置包括由软件或硬件关联到不可共享资源的锁存器。 锁存器的输出连接到总线,以便处理器重新读取信号量。 锁存器的输出还连接到通过其另一个输入连接到信号量的写总线的多路复用器的输入。 锁存器的控制场输出连接到一个与门,其门的另一个输入端通过其输出来接收总线的控制位和调节锁存器的写入。 寻求适应信号量的任务试图用“1”的控制字段将其唯一标识符写入锁存器。 然后重新读取信号量寄存器。 价值重新读取和写入值之间的平等意味着任务已经成功地占用资源。 通过在“0”处的控制字段的写入释放源。
