According to one embodiment, a semiconductor memory device includes a memory and a controller. The memory stores data pieces and search information including entries, where each entry is associated with a search key for specifying one data piece and a real address at which the data piece is stored. Upon reception of a first command, the controller, when the first command specifies a search key, outputs one data piece corresponding to one entry which includes the search key, and when the first command specifies one real address, outputs one data piece corresponding to one entry including the real address.

An entertainment device includes a general-purpose signal processor made up of an assembly of component-processors, each of which can operate in parallel under operating environments independent of others component-processors. A management processor controls a cross bar so as to change the operating environments of the respective component-processors in accordance with a demand for signal processing which is given from a CPU, and to change over any one of the component-processors which receives a signal to be processed which is inputted through the cross bar or outputs a processed signal in accordance with the demand for signal processing.

According to one embodiment, an information processing device includes an OS and a virtual machine switching section. The OS accesses a hardware resource including a nonvolatile semiconductor memory and a semiconductor memory used as a cache memory of the nonvolatile semiconductor memory. The virtual machine switching section switches a virtual machine in exection from a first virtual machine to a second virtual machine while a cache process is executed, when cache miss in a process executed by the first virtual machine is detected.

According to one embodiment, an image processing apparatus includes a processing unit, a tessellation processing unit and a tessellation data storage unit. The processing unit performs interpolation processing on vertex data of a vector image for each sprite. The tessellation processing unit is hardware to perform tessellation processing that generates primitives based on the vertex data from the processing unit. The tessellation data storage unit stores the primitives generated by the tessellation processing unit for each sprite. The processing unit generates a rendering function to render the vector image based on the stored primitives in the tessellation data storage unit, the stored primitives is generated by rendering processing prior to the present rendering processing.

An electric comic book delivering server delivers translated electric comic book by transmitting original electric comic book data, mask data and translation data to a client terminal via a communication network. The mask data is used to mask a display portion of first language. The translation data is used to superimpose a display portion of second language on the masked display portion of first language. When the electric comic book delivering server obtains mask data and translation data from another client terminal in which the mask data and the translation data have been created, the electric comic book delivering server registers the mask data and the translation data into a database thereof. The comic book delivering server transmits payment demand information to a client whenever the server transmits, to the client, the original electric comic book data, the mask data and the translation data thus registered.
