Patent number: 8397003Abstract: There are provided a CPU connection circuit and a method by two CPUs by alternately conducting a changeover between two buffers disposed there between to prevent an event that data processing cannot be fully executed by the CPU on the receiving side. There is included a memory controller which monitors whether or not an amount of data stored by a CCPU 1 in either one of buffers 301 and 302 reaches a predetermined threshold value; when the amount of data stored by the CCPU 1 in the buffer 301, 302 reaches the threshold value, the memory controller requests an ACPU 2 to acquire the data stored in the buffer and changes the storage destination of data from the CCPU to the other one of the buffers; the threshold value is a value more than a unit quantity of data which the CCPU 1 sends to the buffer 301, 302.Type: GrantFiled: July 2, 2012Date of Patent: March 12, 2013Assignee: NEC CorporationInventors: Takao Nakagawa, Takashi Tachikawa, Naoyuki Nakamura, Tadashi Tsukamoto, Toshikatsu Hosoi, Hiroshi Kurakane
