Abstract
A multiplex apparatus includes a plurality of systems configured to be connected to each other by links. Each of the plurality of systems includes a CPU, a pseudo legacy device and a legacy device. The pseudo legacy device is configured to be electrically connected to the CPU. The legacy device is configured to be electrically connected to the pseudo legacy device. The pseudo legacy device includes a request buffer and a pseudo operator. The request buffer is configured to store a request when the CPU sends the request through the pseudo legacy device to the legacy device. The pseudo operator is configured to execute an emulation with regard to the legacy device based on the request, and store the emulation result including an inside status of the legacy device.
Claims14
A multiplex apparatus comprising:
- a plurality of systems configured to be connected to each other by links,
- wherein each of said plurality of systems comprises:
- a CPU,
- a pseudo legacy device configured to be electrically connected to said CPU, and
- a legacy device configured to be electrically connected to said pseudo legacy device, said pseudo legacy device comprises:
- a request buffer configured to store a request when said CPU sends said request through said pseudo legacy device to said legacy device, and
- a pseudo operator configured to execute an emulation with regard to said legacy device based on said request, and store said emulation result including an inside status of said legacy device.
A method for multiplexing a legacy device, comprising:
- (a) providing a computer system which includes;
- a plurality of systems configured to be connected to each other by links,
- wherein each of said plurality of systems comprises:
- a CPU,
- a pseudo legacy device configured to be electrically connected to said CPU, and
- a legacy device configured to be electrically connected to said pseudo legacy device;
- (b) storing a request when said CPU sends said request through said pseudo legacy device to said legacy device by said pseudo legacy device;
- (c) executing an emulation with regard to said legacy device based on said request by said pseudo legacy device;
- and
- (d) storing said emulation result including an inside status of said legacy device by said pseudo legacy device.
