Publication number: 20060218313Abstract: A DMA circuit operates a plurality of DMA channels in parallel, enabling reduction of the circuit scale and fewer development processes. A channel manager circuit reads in sequence the control information for each DMA channel from control memory, performs analysis, and according to the divided DMA control sequence, performs state processing (DMA control). Further, the channel manager circuit updates the control information, writes back the control information to the control memory, and executes time-division control of the plurality of DMA channels. Hence the circuit scale can be reduced, contributing to decreased costs, and the number of development processes can be reduced.Type: ApplicationFiled: September 8, 2005Publication date: September 28, 2006Applicant: FUJITSU LIMITEDInventors: Terumasa Haneda, Yuichi Ogawa, Toshiyuki Yoshida, Yuji Hanaoka

Patent number: 7020163Abstract: The present invention relates to a frame communication system composed of a code converter and a frame generator/decomposer. In order to improve a line efficiency without encapsulating transmitting data, a code converter in a frame transmitting device converts at least different specific codes X and Y within the transmitting data respectively into codes (Y, A) and (Y, B) composed of the code Y and at least specific codes A and B different from each other, and a frame generator prepares a frame of the transmitting data with the code X as a frame boundary. A frame decomposer in a frame receiving device recognizes a specific code X as a frame boundary to decompose receiving data, and a code converter converts codes (Y, A) and (Y, B) within the receiving data composed of a specific code Y, and specific codes A and B into codes X and Y.Type: GrantFiled: January 29, 2002Date of Patent: March 28, 2006Assignee: Fujitsu LimitedInventors: Toshiyuki Yoshida, Takeo Kubo, Takaharu Kajiwara, Tsuyoshi Matsumoto, Hidetoshi Amari, Masashi Hirome
