Method and apparatus for suspending a software virtual machine

A computer system includes a software virtual machine (such as Java) for running one or more applications. An object is provided that is responsive to a call from an application for placing the virtual machine and application into a state of suspension. This involves interrupting all current threads, and recording the state of the components of the virtual machine, including heap, threads, and stack, into a serialization data structure. Subsequently the serialization data structure can be invoked to resume the virtual machine and application from the state of suspension. Note that many virtual machines can be cloned from the single stored data structure. One benefit of this approach is that a new virtual machine can effectively be created in an already initialized state.

Programmable logic device

An object is to provide a programmable logic device having logic blocks connected to each other by a programmable switch, where the programmable switch is characterized by an oxide semiconductor transistor incorporated therein. The extremely low off-state current of the oxide semiconductor transistor provides a function as a non-volatile memory due to its high ability to hold a potential of a gate electrode of a transistor which is connected to the oxide semiconductor transistor. The ability of the oxide semiconductor transistor to function as a non-volatile memory allows the configuration data for controlling the connection of the logic blocks to be maintained even in the absence of a power supply potential. Hence, the rewriting process of the configuration data at starting of the device can be omitted, which contributes to the reduction in power consumption of the device.
