    Patent number: 4167781
    Abstract: A microprocessor system wherein a plurality of programs shares a single central processing unit. A first subsystem includes a memory having a program counter for indicating the point of execution of a program and a data pointer indicating the location in memory of data processed by the program in execution. At least one other subsystem includes a memory having a program counter for indicating the point of execution of a program and a data pointer indicating the location in memory of data being processed by the program in execution in that subsystem. A console control module is interconnected with the system data bus and the first and second subsystems, and controls operation of the central processing unit with each subsystem. The subsystem not connected to the central processing unit indicates the point of interruption of program execution with the program counter and indicates the location of data being processed by the interrupted program.
