Title:
情報処理装置、情報処理方法およびプログラム
Document Type and Number:
Japanese Patent JP4748206
Kind Code:
B2
Abstract:
There is provided an information processing apparatus according to the invention including a bilinear map selection unit for selecting a bilinear map used for a predetermined operation, a group selection unit for selecting at least two types of groups G1 and G2 used in performing the operation, a determination parameter calculation unit for calculating a determination parameter including at least either one of a computation amount required for the predetermined operation and an information amount for the predetermined operation based on each of the selected at least two types of the groups, and a group decision unit for deciding a group used in performing the operation based on the determination parameter. The group decision unit exchanges contents of the groups G1 and G2 when the computation or information amount for the group G2 is more than that for the group G1.
