Data Device Corporation (DDC) is pleased to announce the introduction of the BU-65565 MIL-STD-1553 PMC card. The BU-65565 provides a complete hardware and software COTS solution for interfacing between an embedded system with a PCI bus and one or more 1553 buses. The BU-65565 includes between one and four dual redundant 1553 channels on a convection-cooled or conduction-cooled card. The design of the BU-65565 leverages DDC's latest 1553 terminal series, the Enhanced Mini-ACE™. The BU-65565's PCI interface is a fully compliant target agent, providing a 32-bit interface that operates at clock speeds of up to 33 MHz in either 3.3 volt or 5 volt signaling environments. The interface supports PCI interrupts and contains a 32 X 32 FIFO to accelerate burst write transfers from the PCI host.
Each 1553 channel may be independently programmed for BC, RT, selective message monitor, or RT/monitor modes, providing support of MIL-STD-1553A/B, STANAG-3838, McAir, and MIL-STD-1760. In addition to providing software compatibility with DDC's older generation ACE and Mini-ACE™ (Plus) terminals, the Enhanced Mini-ACE™s incorporate many advanced architectural features. For example, the BC's highly autonomous message sequence control engine provides a means for offloading the host processor for implementing multi-frame message scheduling, message retry and bus switching schemes, data double buffering, and asynchronous message insertion.
The Enhanced Mini-ACE™ RT offers the choice of single, double, and circular buffering for individual subaddresses or a global circular buffering option for multiple (or all) receive subaddresses, a 50% rollover interrupt for circular buffers, and an interrupt status queue for logging up to 32 interrupt events. Other features of the BU-65565 include fully autonomous built-in self-tests of protocol logic and RAM, and built-in RAM parity checking.
The BU-65565 is supported by free software, including a C++ library and VxWorks driver. The library and driver comprise a suite of C function calls that serve to offload a great deal of low-level tasks from the application programmer. The software supports all of the Enhanced Mini-ACE™'s advanced architectural features. As a means of greatly reducing the code size for embedded systems, the software tools support the offline development of binary image files, which may then be downloaded to the BU-65565 at run time by the PCI host.
The standard BU-65565 board minimizes power consumption by using 3.3 volt power for its PCI interface and 1553 logic. A non-standard version of the card requiring only +5 volt power is also available. To provide thermal conduction, the conduction-cooled version of the BU-65565 includes thermal vias and a black anodized aluminum plate.
Data Device Corporation is an international leader in high-reliability data conversion interface components and subsystems for military and commercial applications. Established in 1964 with the introduction of the first synchro-to-digital module, DDC's design and manufacturing facility is located in Bohemia, New York.
