摘要： The present invention makes moving-image coding and decoding with low power consumption possible even when a Context-based Adaptive Binary Arithmetic Coding (CABAC) process is used. A preprocess for coding an image is executed for each macro block (MB), the MB information that is the result of the process is written into a storage unit in the order in which the MBs were processed, and the MB information stored in the storage unit is read out in order of raster and the MBs are coded. When the coded image is decoded, the MBs constituting the coded image are decoded in order of raster, the MB information that is the result of the decoded process is stored in the storage unit, and a decoded information readout process that is a post-process for decoding the image is executed in the order in which the MBs were processed.

摘要： A power storage system is provided with charge switches, discharge switches, a bidirectional DC/DC converter and a power storage system controller connecting all the battery packs to an external circuit to achieve parallel charge and discharge, and the power storage system starts the charge by setting a rated charge current value per one battery pack to Iset and setting the rated charge current value Iset as an initial value of a charge current command value Iref(1), thereafter monitor the charge current of each of the battery packs after elapse of a predetermined time so as to subtract its maximum value Ibmax(1) from the charge current command value Iref(1), and add the rated charge current value Iset to result of subtraction Ierr (Iref(1)−Ibmax(1)) so as to set as a new charge current command value Iref(2) and carry out pre-charge in such a manner as to carry on the charge.

摘要： An image compression/decompression device achieving increased utilization efficiency of the memory bandwidth in the access to the memory used for the compression/decompression operation while maintaining ill effect on the images at a low level is realized. The image compression/decompression device comprises a data conversion unit which reduces the data access rate when original images (as input images at the time of performing the compression) and reference images (used for performing the interframe prediction) are stored in the memory by accessing the memory. The access to the memory is performed in an address sequence (order) that differs between data write and data read. This makes it possible to increase the utilization efficiency of the memory bandwidth, and further to reduce the capacity of the buffer memory used for the data read.
