Abstract: A control device comprises a plurality of processor clusters, and a controller including memory device, wherein the controller is configured to generate a first virtual machine and a second virtual machine different from the first virtual machine, wherein a first operation is performed by using the first virtual machine and a second operation different from the first operation is performed by using the second virtual machine on the plurality of processor clusters, wherein the second operation is stopped by a suspend operation for the second virtual machine and data for the second virtual machine is stored in the memory device, wherein the first operation is stopped by a suspend operation for the first virtual machine and data for the first virtual machine is stored in the memory device, wherein the second operation is performed by a resume operation for the second virtual machine while the first operation is being stopped.

Abstract: A controller that reduces power consumption and has improved performance is provided.
