Patent number: 8539170Abstract: This invention makes it possible to use an inexpensive memory as the line memory of a decoding circuit. To do this, a command comparator separates compressed data into a first command that requires memory access and a second command requires no memory access. A decoder requests memory read of decompressed data necessary for decompression of the first command, decodes the first command based on the decompressed data, and requests memory write of decompressed data obtained by decoding. A RAM access controller controls read and write of a RAM cache and a line memory and executes memory read and memory write corresponding to a request from the decoder.Type: GrantFiled: January 29, 2008Date of Patent: September 17, 2013Assignee: Canon Kabushiki KaishaInventor: Toshio Sakurai

Patent number: 7774795Abstract: A printer receives image information from a host computer and performs printing based on the image information. When an optional unit is newly attached to the printer, the printer changes the device ID which is selected from an ID ROM in accordance with the optional unit. Then output from an interface circuit is changed so that the host computer detects the change of the output from the interface circuit. The host computer makes a device-ID request to the printer to obtain the device ID corresponding to the optional device. Then the host computer determines whether or not a printer driver which is currently operative corresponds to the printer with the newly-attached optional device.Type: GrantFiled: June 8, 2006Date of Patent: August 10, 2010Assignee: Canon Kabushiki KaishaInventor: Toshio Sakurai
