Patent number: 9876608Abstract: In an encoding method, data segments and encoding information which indicates encoding patterns each representing a set of data segments used for a predetermined encoding calculation are acquired. An encoded data piece is generated by performing the predetermined encoding calculation based on each encoding pattern, and is stored in the memory. A first encoding pattern for generating the encoded data piece is compared to a second encoding pattern for a next encoding calculation, and the next encoding calculation is performed by using the encoded data piece corresponding to the first encoding pattern when at least a part of the second pattern is common with the first encoding pattern.Type: GrantFiled: March 25, 2016Date of Patent: January 23, 2018Assignee: FUJITSU LIMITEDInventors: Hiroaki Kameyama, Shinichi Sazawa, Hiroyuki Higuchi
