MIL-STD-1553 IP Cores -- An Emerging Technology

The MIL-STD-1553 serial data bus is widely used for control purposes in avionics, aircraft and space systems. Forty years since its release, 1553 is evolving from traditional integrated circuits (IC) to intellectual property (IP) cores integrated with Field Programmable Gate Array (FPGA) logic.

IP cores offer many advantages over traditional 1553 ICs including lower cost, reduced size, easy ability to update, improved availability and lifecycle control. Combining the benefits of FPGAs and IP cores provides a small-size, robust, reliable, and future-proof solution for MIL-STD-1553 interface perfect for custom board implementations.

The history of MIL-STD-1553, the advantages and requirements of 1553 IP cores compared to standard ICs, and IP core design best practices are discussed in this white paper.
