The battery-to-battery switch is turned on while the bypass switch is turned off in the first move. The battery-to-battery switch is turned off while the bypass switch is turned on in the second mode.

Abstract: When a plurality of OSs are mounted, it is desirable to efficiently use memory resources without affecting other OSs. Also, even if the OSs are different from each other, they are mounted on one system, and therefore, inter-OS communication is required.

Accordingly, an information processor includes: a firmware for assigning a first central processing unit, a first operating system, and a first region being a partial region of a memory as a first domain, assigning a second central processing unit, a second operating system, and a second region being a partial region of the memory as a second domain, and controlling to disable an access of one domain to a region assigned for the other domain; and a middleware for controlling a communication when the data communication is required between the first domain and the second domain.

Abstract: The present invention relates to an encoding device for saving the number of bits of codes. In step S11, the differential value between a normalization coefficient Bi to be encoded and a normalization coefficient Bi-1 for an encoding unit Ai-1 in a band adjacent to the lower side of an encoding unit Ai corresponding to the normalization coefficient Bi is computed. In step S12, reference is made to a table in which a differential value having a high frequency of occurrence is associated with a code having a small number of bits, and a code corresponding to the computed differential value is read. In step S13, it is determined whether or not all normalization coefficients B have been encoded. If it is determined that all normalization coefficients B have been encoded, in step S14, the code read in step S12 is output. The present invention is applicable to an audio recorder.
