摘要:
A protocol conversion apparatus for converting a communication system (e.g. a USB scheme and a PDC scheme) is disposed between for example, a personal computer (PC) and a portable telephone (MS). A radio protocol packet is covered with USB protocol header/footer in its entirety, or the USB protocol header/footer is removed simply to generate the radio protocol packet.

An information processing apparatus includes a fingerprint sensor that detects movement of a finger, and a transforming unit that transforms the movement of the finger detected by the fingerprint sensor into an input event corresponding to an operational instruction to an application that runs on the information processing apparatus. When an amount of movement of the finger detected by the fingerprint sensor is greater than a threshold for the amount of movement, the transforming unit inhibits transformation of the movement of the finger detected by the fingerprint sensor into the input event.
摘要:
An access-request control method of controlling an access request from an application to a communication device, to which at least a general-purpose port is allocated, that performs a communication via a communication network in response to the access request, includes permitting a utilization of the communication device prior to the access request from the application; and controlling whether to accept the access request to the communication device from the application, based on a permission status for the utilization of the communication device.

摘要:
A portable terminal includes a finger sensor that recognizes, in response to contact of a finger, the contact and a movement of the finger; and a conversion unit that converts the movement of the finger recognized by the finger sensor into an input event corresponding to an operation instruction to an application running on the portable terminal. If a period of time from recognition of release of the finger from the finger sensor to recognition of placement of the finger on the finger sensor is less than a predetermined amount of time corresponding to physical limitations of a human, the conversion unit does not convert to the input event the recognition of placement of the finger, and recognition of a movement of the finger until recognition of release of the finger after the recognition of placement of the finger.

A data transfer apparatus improving data transfer rate regardless of the original transfer mode in a USB interface is disclosed. A computer includes a bulk packet generation unit and an isochronous packet transmission unit. The bulk packet generation unit generates a bulk packet (or a control packet) which is a USB packet and has a predetermined structure including a first data area by describing data which is taken as an object of transfer in the first data area. The isochronous packet transmission unit generates an isochronous packet which is a packet in USB isochronous transfer and has a predetermined structure including a second data area by incorporating at least one bulk packet into the second data area, and isochronously transfers the isochronous packet to the mobile telephone over the USB interface.

A memory controlling device is controlled by a CPU to enable information to be read from memory when the memory starts an operation. The memory is capable of retaining data during a power off state and the data is loaded when the memory starts an operation.
摘要:
A buffer access control circuit to access a buffer which is divided into an upper buffer and a lower buffer which are assigned the same address and a memory unit including the buffer access control circuit. The buffer access control circuit includes latch circuits which store data in response to upper and lower buffer access signals, and a first detection circuit which detects whether data latched by the latch circuits match. A modifying circuit inputs data to the first and second latches or inputs inverted data to the first and second latches when one of the upper and lower buffer access signals is generated and the detection circuit detects a match. In this manner, the buffer access control circuit is used to update an address one by one, without the use of a delay circuit when consecutively accessing the upper and lower buffers.

A circuit for enabling a chip, usable for both a first device capable of having m chips and a second device having more than m chips, includes a first generation unit which generates a chip-enable signal that includes a bit pattern of m bits for enabling one of the m chips indicated by a chip number, a second generation unit which generates a chip-enable generation signal that is to be decoded into a chip-enable signal of at least 2m bits for enabling one of the more than m chips indicated by the chip number, the chip-enable generation signal including a bit pattern identical to the bit pattern of m bits when the chip number is equal to a specific number, and a selection unit which selects and outputs the chip-enable signal generated by the first generation unit when the circuit is used for the first device, and selects and outputs the chip-enable generation signal generated by the second generation unit when the circuit is used for the second device.
