Core1553BRT provides a complete, dual-redundant MIL-STD-1553B remote terminal (RT), apart from the transceivers required to interface to the bus. It simply provides a set of memory-mapped subaddresses that "receive data written to" or "transmit data read from." The core can be configured to connect directly to synchronous or asynchronous memory devices. Alternatively, the core can directly connect to backend devices, removing the need for memory buffers. If memory is used, the core requires 2,048 words of memory, which can be shared with the local CPU.
