The 1553B RT Core implements a Remote Terminal as specified in the MIL-STD-1553B specification, including Notes 1 through 7.
MIL-STD-1553B is the military specification defining a Digital Time Division Command/Response Multiplexed Data Bus operating at 1 Mbps. The 1553 databus is a dual-redundant, bidirectional, Manchester II encoded databus with a high bit error reliability. All bus communications are controlled and initiated by the bus controller. Remote terminal devices attached to the bus respond to controller commands.
The 1553B RT Core has been developed to DAL A according to the DO-254. For lower DAL levels reduced documentation sets are available. The core is also available as a netlist for DAL D or projects not needing the full RTL source.
