    摘要: A data transfer control device and controlling method in which data on a storage medium is read continuously. The data transfer control device includes M storage units each for storing respectively at least two kinds of different data among N kinds of data in memory regions, a transmission control element for transmitting the N kinds of data and a spare storage unit for storing at least one kind of data among said N kinds of data. The transfer control device includes a judging element for judging whether accessing any one of the M storage units must be halted. Switching element for switching a memory region to the spare storage unit and the remaining (M-1) storage unit when the judging element judges that accessing must be halted and then the switching element performs an accessing operation. The data transfer control device can suppress an increase in the device forming cost, power consumption, and installation area, and can increase the amount of data which can be stored according to the number of storage units installed.

    摘要: A CPU, a main memory, a network interface section and a control section are connected to an internal bus. The control section is connected to a storage device to control read-out and write-in processes relative to the storage device. The network interface section receives an access request to the storage device transferred through a network and sends it to the control section through the CPU. The network interface section and the control section are connected to each other by an exclusive line. Data read out of the storage device and data to be written into it is transferred through the exclusive line.

    摘要: Encoding and decoding systems for a digital image communication apparatus suppresses any reduction in the encoding efficiency due to leaky prediction. A range correcting unit (3) corrects the range of data of a preceding frame stored in a memory (1) according to a reference value outputted from a reference value outputting unit (2). Thereafter, a leak coefficient multiplying unit (4) multiplies the data by a predetermined leak coefficient and outputs the product data. The data outputted from the leak coefficient multiplying unit (4) are uncorrected by an uncorrecting unit (5) to restore the range corrected by the range correcting unit (3). A predictive error outputting unit (6) detects the difference between the digital image data of an inputted present frame and the data uncorrected by the uncorrecting unit (5), and outputs the difference as a predictive error. A predictive error encoding unit (7) encodes the predictive error outputted from the predictive error outputting unit (6), and outputs the encoded predictive error.

The system for dividing input frame data into a plurality of blocks before transmitting them comprises on its sending side an intra-frame/inter-frame determiner for receiving intra-frame data and inter-frame data and selecting either of them for output, and a difference collator for having the intra-frame/inter-frame determiner compulsorily output intra-frame data at the time of data input for the next frame when one or more data in each block forming inter-frame data are larger than a predetermined threshold. The system also comprises on its receiving side an picture element domain frame data storage for storing received data in the picture element domain, and a motion vector detector for detecting according to the contents in the storage a motion vector using the data in the block surrounding the discarded block in order to guess the data in the discarded block.
