Abstract

PURPOSE:To transmit efficiently and exactly all combination data of eight bits as data other than transmission control characters by normal transmission control procedures, by dividing eight-bit data groups into six-bit data groups and transmitting and receiving them. CONSTITUTION:Information in memory controller 11 is sent to line 13 through communication controller 12, and information from line 13 is inputted to controller 11. At a transmission time, continuous three digits of eight-bit information is divided into four digits of six-bit information befoer transmission, and two-bit redundant bits are added to divided six-bit information, and information is transmitted as a eight-bit code other than transmission control characters. At a receiving time, two- bit redundant bits are removed from the recieved continuous four-digit eight-bit code to obtain four-digit six-bit information, and four-digit six-bit information of the output is converted to three-digit eight-bit information.
