Abstract: According to one embodiment, a decoding device includes a storage section, a control section, a decoding processing section. The storage section stores control information showing a progress state of process stages for a decoding process as to a plurality of processing data included in coded data. The control section allocates process stages corresponding to executable processing data which is executable in parallel, to a processor on the basis of the control information, a dependence relation between the processing data in the decoding process, and a dependence relation between the process stages. The decoding processing section parallelly executes allocated process stages corresponding to the executable processing data.

Abstract: An information processing apparatus stores in a function expansion card removably housed in an expansion slot add-in programs for reading additional information such as multimedia information included in the electronic mail. The apparatus includes a list table that correlates the individual information types of additional information with the add-in programs. In the apparatus, an add-in program execute section loads the add-in program selected based on the list table from the function expansion card and executes the program. A user interface section provides a screen for the user to arbitrarily set a correlation in the list table. An indicator display section enables the user to visually check the list table.
