A kind of ip core of 1553b communication unit

Abstract

The invention discloses an IP (internet protocol) core of a 1553B communication unit. The IP core comprises a protocol initializing module, a data caching module and a read-write interface module, wherein the read-write interface module comprises a read-write module data bus, a read-write module address bus and a read-write module control signal; the read-write module data bus is connected with the protocol initializing module and the data caching module respectively; the read-write module address bus is connected with the initializing module; the read-write module control signal is connected with the initializing module and comprises a read enabling signal and a write enabling signal; the read-write module data bus, the read-write module address bus, an external bus controller and an external processor are connected with a PLB (processor local bus). The IP core can realize a communication function of the 1553B communication unit and conveniently realize protocol modularized encapsulation, so that the safety of a top user protocol is improved.

Description

technical field [0001] The invention belongs to the field of unmanned aircraft communication, and in particular relates to an IP core of a 1553B communication unit. Background technique [0002] At present, the existing 1553B communication equipment realizes the data protection through the communication controller, and the processor implements the node communication by means of function calling in the top-level program. However, since the 1553B communication device only encapsulates the 1553B bottom layer protocol, the top layer user protocol is implemented in the processor. The general top-level user protocol does not carry out program encapsulation, and it is easy to be cracked by other users, which is not conducive to program security. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides an IP core of the 1553B communication unit, which solves the problems in the prior art that the top-level u...
