Abstract

The invention discloses a high-speed LVDS serial synchronization communication controller. The high-speed LVDS serial synchronization communication controller comprises a microcontroller interface module (1), a work register array module (2), a receiving time sequence generator module (3) and a sending time sequence generator module (4). The high-speed LVDS serial synchronization communication controller can be matched with a serializer MAX9217, a deserializer MAX9218 and other customized integrated circuits of a Canada MAXIM company to form a full duplex and high speed LVDS synchronization serial communication interface. A control order, parameters and data given by an X80 series microcontroller can be received, the information exchanging process is controlled, and the working state of the high-speed LVDS serial synchronization communication controller is fed back to an X86 series microcontroller. When one frame of data are received or sent, an interrupt request signal of the X86 series microcontroller can be automatically produced. A user system can be assisted to achieve an information exchange protocol defined by a user, reliable high-speed, serial and synchronous full duplex data exchange between two electronic information systems connected through an LVDS signal line is achieved.

Description

technical field [0001] The invention relates to a communication controller, in particular to a high-speed LVDS serial synchronous communication controller. Background technique [0002] Deep coupling integrated navigation technology is one of the frontier topics of long-distance navigation and positioning systems. The hardware operating platform of this technology is an integrated navigation information processor. Since a large amount of information data needs to be received from the satellite navigation information receiver, it can be integrated with the local inertial measurement The navigation information output by the device is fused. Therefore, the performance of the hardware interface and communication line between the navigation information processor and the satellite navigation information receiver directly affects the running speed of the deep coupling integrated navigation algorithm, thereby affecting the deep coupling integrated navigation. technical performance. ...
