RT53EUR - HDL


MIL-STD-1553B Remote Terminal IP Core.
 
Overview
  
The RT53EUR IP core is a classic 1553B Remote Terminal. When used in nominal and redundant mode, it is connected to the 1553B bus with the following elements:

• Two single 1553B Transceivers, or a dual 1553B Transceiver
• Two 1553B Transformers
• A stable oscillator that delivers the IP clock frequency

The connection of the RT53EUR IP core to a 1553B bus is as shown in the figure below.

The RT53EUR IP core can be functionally divided in 2 parts: the 1553B interface and the Application Interface. The RT53EUR contains the following functions:

• A nominal and a redundant Manchester decoder
• A nominal and a redundant Manchester encoder
• A redundancy management function
• A protocol management function
• An application management function

The block diagram of the RT53EUR IP core is depicted in the figure below.

 Area/Speed Results
  
The RT53EUR is delivered as a generic technology netlist format, and can be targeted to any ASIC or FPGA technology, including Actel and Xilinx FPGAs. As an indication, the area/speed results when targeting an Actel RTAX2000 FPGA are as follows:

Actel RTAX2000
- Combinational Cells : 2782 of 21496 (13%)
- Sequential Cells : 960 of 10752 ( 9%)
- Total Cells : 3742 of 32248 (12%)
- Clock frequency : 55.5 MHz (functional frequency from 10 MHz to 24 MHz in steps of 2 MHz)
