    • A multiple processor communications system including a control processor and a scan processor having its own program counter enabling the efficient execution of subroutines. The scan processor directly accesses a compiled user memory which contains its operating program and also directly accesses the image memory which contains the input and output data to perform the computations required by the program. The system includes error codes for distinguishing various error conditions including collision error conditions indicating illegal commands to the scan processor when it is scanning and parity errors in the compiled user memory and in the image memory.
    • 多处理器通信系统包括控制处理器和具有其自己的程序计数器的扫描处理器,能够有效执行子程序。 扫描处理器直接访问包含其操作程序的编译用户存储器,并且还直接访问包含输入和输出数据的图像存储器,以执行程序所需的计算。 该系统包括用于区分各种错误条件的错误代码,包括当扫描处理器扫描时指示非法命令的冲突错误条件以及编译的用户存储器和图像存储器中的奇偶校验错误。
