Abstract: A communication system performs communication while switching between full-duplex communication and half-duplex communication. A slave device, which receives command packet signals requesting to write or read data from the master device, stores information in a response packet signal that specifies half-duplex communication in response to one of the received packet signals, and transmits the response packet signal to the master device, when the number of the received command packet signals has reached the maximum number of the command packet signals storable in a command signal queue.

Abstract: A host device and a slave device are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode.

Abstract: A data communication system for starting transmission and reception of target data for processing upon recognition that switching between communication modes is completed. The data communication system includes a master communication device and a slave communication device that continuously perform, at a time of switching from half-duplex communication to full-duplex communication, (i) a handshake using a directional control code indicating the switching and a preamble code indicating completion of the switching and (ii) a handshake using the preamble code and an acknowledge code indicating receipt of the preamble code, whereby each of the devices recognizes that the switching between communication modes by the opposite device is completed and starts transmission and reception of the target data.

Abstract: A request change unit outputs a command as a request under control of a judgment control unit. A response condition determination unit determines a condition that is to be matched by a correct response which is to be returned from the other device-in-communication in reply to the command if the other device-in-communication operates in conformity with a protocol. A check unit checks a response received from the other device-in-communication in reply to the command, against the condition. If the received response does not match the condition but is correctable to match the condition as a result of the check, a response correction unit corrects the received response to match the condition under control of the judgment control unit.

Abstract: A DMA control device and a data transfer method, which make it possible to use a DMA channel independent of an operation mode of a processor and realize the protection of DMA control parameters during DMA operation (during a data transfer), while reducing the number of shift of an operating mode of the processor as small as possible, are provided. In requesting a DMA start by locking an access to a ch-0 DMA control register 114 in a secure mode, a CPU 101 instructs an unlock set register 118 to release an access lock when the transfer is completed. Then, when a parameter controlling circuit 119 receives a notification of transfer completion from a ch-0 state managing circuit 116, such parameter controlling circuit instructs a lock set register 115 to release the lock in accordance with the setting of the unlock set register 118.

Abstract: An interrupt request cannot be transmitted while a data read command or a data write command transmitted from a host device to a slave device is being processed in a half-duplex mode. Disclosed are a host device and a slave device that are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode.

Abstract: A processor (10) manages, in an instruction management unit (103) and a data attribute management unit (105), secure attributes indicating whether instruction code and data stored in an instruction cache (102) and a data cache (104) of the processor (10) are confidential information. When the instruction code and the data are confidential information, the processor (10) also manages secure processing identification information for indicating in which secure process the confidential information is to be used. When the operating mode is switched from the secure mode to the normal mode, only the confidential information is disabled by a memory disabling unit (108). This prevents confidential information from being analyzed by the processor in the normal mode.

Abstract: In a communication system for performing communication while switching between full-duplex communication and half-duplex communication, a slave 200, which receives command packet signals requesting to write or read data from the master 100, houses information, in a response packet signal, that specifies half-duplex communication in response to one of the received packet signals, and transmits the response packet signal to the master, when the number of the received command packet signals has reached the maximum number of the command packet signals storable in a command signal queue 252.

Abstract: A data store system and a data restoration system that can decrease power consumed in data store-processing or data restoration are provided. A data transfer system includes a function block having store data; a storage section for storing the store data transferred from the function block; a bus having a bit width of a predetermined number of bits where the function block and the storage section are connected; and a controller for sending a store period clock to the function block and the storage section at the data store-processing and sending a restoration period clock to the function block and the storage section at the data restoration. In synchronization with the store period clock, the function block sends store data a predetermined number of bits at a time within the bit width of the bus to the bus and the storage section stores the store data sent in sequence from the function block through the bus.

Abstract: A memory device with a nonvolatile memory and RAM for accessing the nonvolatile memory is generally provided with a table to convert a logical address to a physical address, however, in the invention, the table is divided to a first table on RAM and a second table on the nonvolatile memory. The first table converts specific bits of the logical address to a first physical address indicating a location of the second table. The second table converts the other bits of the logical address to a physical address of a representative page of pages contained in a storage area corresponding to the logical address. A unit operable to access data (a writing unit operable to, a reading unit operable to, and an erasing unit operable to) reaches a target physical address based on the logical address. Such configuration can reduce the capacity of each conversion table.
