PROBLEM TO BE SOLVED: To improve data transmission efficiency in a system for performing partial processing in which processing is hieratically defined by an engine section in a hardware configuration. SOLUTION: When a plurality of processing hierarchies include common ranges processed (S100-YES), the processing of a common portion at the upstream side is set to be unfinished processing (S102), and a command descriptor is generated (S106) and stored in a command descriptor region (S108). After that, control is shifted to processings of processing hierarchies at the downstream side(S110), the command descriptor is generated (S116), a command descriptor cue is created (S118), and processing at an engine section is activated (S120). At the engine section, the command descriptor of the command descriptor cue is read for an analysis (S130), data to be processed are read according to procedures based on the analyzed result (S132), and prescribed processing is performed in prescribed orders for preventing the common portion from being transferred overlappingly (S140).
