Sital Technology, the leader in IP cores and products compliant with Mil-Std-1553, announced today the release of OCTAVA™, a Mil-Std-1553 communication engine, compatible with DDC® Enhanced MiniACE® devices.
The OCTAVA™ family integrates the BRM1553D Mil-Std-1553 a protocol processing unit, a pair of 5-volt transceivers, memory administration, processor connectivity logic, and either 4K or 64K words of RAM, all encased in a 72-pin Plastic Quad Flat Pack (PQFP) package. The family consists of two-way data buffers and built-in address latches, facilitating a direct interface with the host processor bus. The memory management scheme for RT mode provides three data structures for buffering incoming and outgoing data. Combined with the extensive interrupt capability, these structures serve to guarantee data consistency whilst off-loading the host processor.
These memory management features offer flexible data structure management, essential for optimizing the handling of incoming and outgoing messages. This flexibility allows for efficient organization and access to data, which is particularly beneficial in systems that require rapid processing and retrieval of communication messages. Such a design not only enhances system performance but also contributes to a reduction in processor load, allowing for smoother operation and better resource allocation.
By incorporating advanced data integrity mechanisms, OCTAVA™ leverages the robustness of the MIL-STD-1553 protocol to ensure secure and reliable data transmission. These mechanisms are critical in environments where data accuracy is paramount, such as in aerospace and defense applications.
The integration of error detection and correction algorithms directly into the communication engine minimizes the risk of data corruption. It ensures that transmitted information remains intact and reliable across complex systems.
The OCTAVA devices can also boot-up as RT with the busy bit set for 1760 applications. The BC mode incorporates numerous functionalities designed to offer an effective real-time software interface to the host processor. These include versatile interrupt creation, automatic repetition of frames, customizable inter-message gap durations or message rates, and automated retry mechanisms.
The OCTAVA™ devices are pin-to-pin compatible with the DDC® BU-65178 and BU-61688 and as such serve as a perfect drop-in electrical, physical and software replacement. The pin-to-pin compatibility facilitates seamless integration into existing avionics boards. An avionics board designed with the DDC® BU-65178 and BU-61688 can work seamlessly with the OCT-65178 and OCT-61688 without hardware or software changes.
This compatibility feature is a significant advantage for systems engineers and designers, enabling an easy upgrade path to incorporate the latest MIL-STD-1553 communication capabilities. It simplifies the migration process, ensuring that system updates can be implemented swiftly and with minimal disruption to ongoing operations.
“The OCTAVA™ family completely changes the Mil-Std-1553 market. A market that was previously dominated by a single vendor will now benefit from the power of competition”, said Duli Yariv, VP of marketing for Sital Technology. “OCTAVA™ does not only offer price benefits over the competition, but it also introduces many technology and functional advantages for customers” he added.
OCTAVA™ was introduced in partnership with National Hybrid Inc. (NHi), who designed the transceiver and manufactures the device in the USA.
