Patent number: 6859205Abstract: An inventive line-drawing apparatus draws a line that connects a start point to an end point. The start and end points are both presented on a display and represented by mutually different sets of coordinates. The apparatus includes first and second FIFO memories, an adder and a shifter. Each of the first and second FIFO memories accepts a plurality of input coordinate data and sequentially outputs one of these data after another on a first in, first out basis. The adder receives and adds together the respective coordinate data output from the first and second memories and outputs added data. And the shifter divides the added data by two and outputs divided data. The coordinate data output from the first and second memories are input to the first memory. The divided data is input from the shifter to the second memory. The line connecting the start and end points together is drawn on the display in accordance with the divided data output from the shifter.Type: GrantFiled: October 3, 2000Date of Patent: February 22, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Tetsuji Kishi

Patent number: 5533034Abstract: One data transmitter for transmitting a broadcast data onto an outside data bus and data receivers, whose number is "n", for individually receiving the transmitted broadcast data are provided. A single error signal line is connected in common to the data transmitter and each of the "n" data receivers. Each of the data receivers notifies an error detection to the data transmitter and the other data receivers via the error signal line with a wired OR connector when its own data receivers detects an error. Being notified of the error detection, the data transmitter re-transmits the data so that all of the data receivers re-receive the data. Accordingly, re-transfer per one data at a broadcast transfer is contemplated.Type: GrantFiled: June 22, 1993Date of Patent: July 2, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yuri Kuwata, Ichiro Okabayashi, Tetsuji Kishi

Patent number: 5502733Abstract: There are provided a data transmitter for sequentially transmitting data to which error correcting codes are added, and a data receiver for returning a retransmission request signal if the received data has errors which cannot be corrected. The data transmitter does not confirm that the retransmission request signal related to the transmitted data is received and data are consecutively transmitted from a FIFO memory in a pipeline fashion while holding the transmitted data in a data latch. The data receiver sequentially stores the received data in the FIFO memory on a receiving end in a pipeline fashion. In the case where the retransmission request signal is transmitted from the data receiver, the data transmitter immediately transmits retransmission data which has been prepared in the data latch.Type: GrantFiled: March 2, 1994Date of Patent: March 26, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuji Kishi, Ichiro Okabayashi
