摘要： PROBLEM TO BE SOLVED: To easily cope with plural uses just by exchanging the sheets and without using different devices for every use by preparing a control switch placed on a device, a sheet which can be attached to and detached from the control switch and a means which recognizes the sheet type. SOLUTION: A card type voice information selection/reproduction device includes an operating key 14, a guide which guides the insertion of a sheet 16 put on the key 14, and a connector which recognizes the type of the inserted sheet 16. The voice information is recorded in a memory 11 via a PC card interface 17. When the recorded information is designated by the key 14 serving as a voice information selection means based on a procedure that is prescribed by the type of the sheet 16, a decoder 12 converts the selected data stored in the memory 11 into voice signals. These voice signals are outputted to the outside via a voice output device 13 as analog signals. Then the information is shown on a selected information LCD 15 to identify the selected data.

摘要： PURPOSE:To reduce power consumption in an LSI as a whole by executing a part of simple processing which occupies the most part of algorithm as wired logic in which a dedicated computing element of scale smaller than that of a main computing element performs the transfer of data between data memory via a direct memory access(DMA) bus. CONSTITUTION:Such constitution is employed that the dedicated computing element 201 which performs limited processing on the algorithm is provided, and the dedicated computing element 201 is connected to the DMA buses 212, 212 connected to the data memory 104 and not being connected to the main computing element 106. In other words, the dedicated computing element 201 performs data transfer between the data memory 104 via the DMA buses 211, 212, which enables simple processing to be performed. The dedicated computing element 201 is a computing element of small scale provided with a limited computing function so as to be fitted in the execution of the simple processing. Therefore, it is possible to reduce the power consumption in the operation of the whole digital signal processor, i.e., the LSI in which the simple processing occupies the most part.

摘要： PROBLEM TO BE SOLVED: To prevent easy analysis even when a contact pin is exposed by providing an encipher matrix circuit, with which access to an internal circuit is enabled only when a card is cut into determined shape, at the lower part of card convering. SOLUTION: Inside the thin card covered with plastic or vinyl coating, a circuit part 10 and an encipher matrix part 7 are molded invisible from the outside. When accessing that internal circuit part 10, an external contact terminal 13 is connected to a terminal 8 and required power and signals are transmitted/received. At such a time, when the access to the internal circuit 10 is disabled in case of emergency, coating on the surface is released so as to make the terminal 8 visible, certain specified disconnection 11 is performed by the encipher matrix part 7, and the internal circuit 10 is accessed while securing a regular route 12. Thus, security can be improved.
