专利汇可以提供Data transmission controlling interface with memory专利检索,专利查询,专利分析的服务。并且PURPOSE:To reduce a load on the software of a system by eliminating the need for character-by-character read/write control by software by incorporating a memory in a data transmission controlling interface. CONSTITUTION:An input and output controller 1 is connected to an address bus line, and a memory buffer 5 with about 1K-byte capacity is connected to a data bus line. To the controller 1 and buffer 5, a transmission controlling register 2 connected to a transmitting data line and a reception controlling register 3 connected to a receiving data line are connected, respectively, thus constituting a data transmission controlling interface. For transmission, data is set in the buffer 5 through software and the data in the buffer 5 is transmitted through hardware. For reception, data read in the register 3 is set in the buffer 5 through the hardware, and the data is read through the software, thereby reducing a load on the software of this system.,下面是Data transmission controlling interface with memory专利的具体信息内容。
