SYSTEM AND METHOD FOR 1553 BUS OPERATION SELF CHECKING

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for 1553 bus operation self checking.;SOLUTION: A 1553 self-checking logic manages data communication between a 1553 bus transceiver and a self-checking processor pair. The 1553 self-checking logic includes a primary logic and a secondary logic that operate in lock-step. When the 1553 self-checking logic writes data to the 1553 bus transceiver, the 1553 self-checking logic compares a first 1553 formatted message generated by the primary logic to a second 1553 formatted message generated by the secondary logic, and generates an error indication when the first 1553 formatted message does not match the second 1553 formatted message.;COPYRIGHT: (C)2013,JPO&INPIT
