Abstract

The computer data transmission card is aimed at ensuring high-speed and continuous transmission of data between computer and its peripheral equipment, and its technical scheme includes computer data transmission card, computer, optical fibre transceiver, data serial converter, data parallel converter, high-speed temporary memory, data controller, bus controller and PCI controller. The described data controller is connected with high-speed temporary memory, the data controller is connected with data parallel converter, and the described high-speed temporary memory and the data serial converter are connected by means of 32 data wires between them. Said invention is mainly applicable to high-speed continuous data transmission between computer and peripheral equipment in computer printing plate-making system or large high-speed machine tool control system.

Description

technical field [0001] The invention relates to a data transmission card between a computer and peripheral equipment, especially the occasions requiring high-speed and continuous data transmission between the computer and the peripheral equipment, such as computer printing plate-making system or large-scale high-speed machine tool control. Background technique [0002] In the structure of the current high-speed data transmission card, high-speed, intermittent, and burst transmission are mainly used, and high-speed transmission is used in the transmission process, but the data flow cannot be kept continuous. When the receiving device requires a continuous data stream, only a large-capacity memory is configured on the receiving device as a buffer to keep the data on the device side continuous. In this way, the rate of the transmission equipment is very high, and the bandwidth of the transmission equipment cannot be fully utilized. Moreover, a large-ca...
