General Description
The Core1553BBC provides a complete, MIL-STD-1553B
Bus Controller (BC). A typical system implementation
using the Core1553BBC is shown in
Core1553BBC reads message descriptor blocks from the
memory and generates messages that are transmitted on
the 1553B bus. Data words are read from the memory

and transmitted on the 1553B bus. Data received is
written to the memory. The core can be configured
directly to connect to synchronous or asynchronous
memory devices.
The core consists of five main blocks: the 1553B encoder,
the 1553B decoder, a protocol controller block, a CPU
interface, and a backend interface
