Protocol IP Core

The Holt MIL-STD-1553/1760 IP solution is based on Holt’s HI-6130/31 and MAMBATM families and provides a complete single- or multi-function protocol interface between a host processor and MIL-STD-1553B bus. Any combination of BC, RT or MT functions can be operated concurrently. The enabled terminals communicate with the MIL-STD-1553 buses through a shared dual bus transceiver and external transformer, also available from Holt.

 

All RT devices are MIL-STD-1760 compliant, responding to valid messages with status word Busy Bit set within 150ms following power-on.

 

The Holt Multi-Core IP product includes a Verilog IP core, test bench, and supporting documentation, allowing designers to instantiate the core in a variety of FPGA implementations.
