The present disclosure provides a method of copying files at a high speed when accesses to both of a local memory physically connected to an access device and a remote memory connected via a wireless network. A file copy controller in the access device generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, based on file system management information of the local memory and an access list, obtained from another access device, of the remote memory, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller copies data between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in the access device or an internal bus connected to the CPU.

Wireless access device and wireless access system

A recording device operates in accordance with an instruction from an access device. The recording device comprising a nonvolatile memory that stores data, a communication unit that receives an instruction issued by the access device, and a memory controller that controls the nonvolatile memory. When a recording instruction for recording data into the nonvolatile memory is received from the access device, the memory controller starts recording of data into the nonvolatile memory. When the memory controller receives from the access device a suspension instruction for suspending the recording of data, the memory controller stores suspension information into the nonvolatile memory, the suspension information indicating a suspended position as a position in a recording area of the nonvolatile memory at which the data is being recorded upon reception of the suspension instruction.

Recording device, access device, recording system, and recording method

A file copy controller in a wireless access device reads file system management information of both of a local memory and a remote memory, generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller performs copy operation between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in an access device or an internal bus connected to the CPU.

In a communication system, a master device gives a data control to one of a plurality of slave devices, and stops controlling data transmission and reception in the master device. A dual-role device executes the data transmission and reception with the other slave devices according to the data control given by the master device. The master device transmits an abort signal to the dual-role device while data is being transmitted and received by the dual-role device according to the data control. The dual-role device receives the abort signal from the master device, and transmits an interrupt signal to the master device when no data is being transmitted or received. The master device enables data transmission and reception according to the data control after receiving the interrupt signal from the dual-role device. The dual-role device stops data transmission and reception according to the data control after receiving the interrupt signal.

A storage control device including an area control unit, an attribute control unit, and an access control unit. The area control unit determines one or more valid areas for each type of areas included in respective storage areas stored in two or more storage devices to generate a virtual storage having the valid areas as a storage area. The attribute control unit selects, as speed information of the virtual storage, a lowest value of minimum guaranteed speeds in reading and writing which are included among respective pieces of attribute information stored in the two or more storage devices, with reference to the respective pieces of the attribute information. The access control unit transmits information regarding the storage area of the virtual storage and the speed information to a host device that reads and writes data from/to the virtual storage.

Provided is a method for stabilizing and increasing the speed of processing for writing a plurality of different-sized files such as a video file and a management file in parallel in the case where the area in a non-volatile memory of an information recording module is managed by a file system. An access module () includes a means for retaining sequential areas in logical block units as areas for writing file data, and a means for realizing file data addition and overwriting by writing data to logical blocks and changing links in a FAT regardless of whether file data addition or overwriting is performed. Writing to the information recording module is performed by writing to sequential addresses in the logical blocks. This realizes the stabilization of and an increase in the file data recording speed by suppressing needless copy processing performed in the information recording modulein the case of recording a plurality of files such as a video file and a management file in parallel.
