Sital Announces the Release of the OCTAVA MIL-STD-1553 Component

Posted on by Sital_web3D

Sital Technology, the leader in Mil-Std-1553 IP cores and products, 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 protocol engine, a dual 5-volt transceiver, memory management, processor interface logic and 4K or 64K words of RAM in a 72 pin Plastic Quad Flat Pack (PQFP) package. The family consists of bi-directional data buffers and internal address latches to provide a host processor bus with direct interface. 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.

The OCTAVA devices can also boot-up as RT with the busy bit set for 1760 applications. The BC mode implements several features aimed at providing an efficient real time software interface to the host processor including flexible interrupt generation, automatic frame repetition, programmable inter-message gap times or message rate, and automatic retries.

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. 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.

“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.

Sital Successfully Completes Testing of Wiring Bus Diagnostics IP with an Air Force

Posted on by Sital_web3D

Sital Technology has conducted tests of its new patent pending “Tails Code Key” technology for Mil-Std-1553 bus maintenance as part of the BRM1553D IP. The results backed up the theoretical assumptions, previously seen on simulation.

The test was conducted on a F-16 mockup, together with avionics engineers from the Air Force, and proved the need for such technology to overcome wiring and connectors problems, often hard to detect and repair.

“Tail Code Key” is a parametric test that is measured during flight in real time, 50 times a second. These numbers serve as a code – quality code. The code varies as a direct result of the quality of the bus.

If the bus connectors or wires degrade over time and usage, the measured code would change. Technicians get an early warning for problems that should be fixed before they fail the bus.

“I am excited to see theory comes to life”, says Ofer Hofman, founder and R&D Manager of Sital Technology.

Duli Yariv, VP Marketing and Sales of Sital adds: “Tails Code Key will allow Air Forces to dramatically shorten efforts related to avionics bus maintenance. This technology will enable our customers to save time, costs and efforts, currently required, on problems that are related to avionics bus malfunctions and even take preventive measures to fix problems before they occur.”

“Tails Code Key” technology will be integrated with Sital’s successful BRM1553D, BRM1553PCI and BRM1553FE Mil-Std-1553 IP Cores, used by military and aerospace customers around the world.

“Tail Code Key” is a method of enhancing MIL-STD-1553B and CAN bus maintenance quality by means of performing real time parametric testing on the bus. If functional testing results with “go” and “no-go”, which could be scaled as grade 100 and grade 0, “Tail Code Key” is a parametric test that will deliver a grade somewhere between 0 and 100.

There are three important benefits which are gained from the detailed grade:

The ability to detect failures before they impact functionality.
Physical location of failure on the bus.
Detection of single failure events during flight.

“Tail Code Key” is a set of numbers that are measured during flight in real time, 50 times a second. These numbers serve as a code – quality code. The code varies as a direct result of the quality of the bus.

If the bus connectors or wires degrade over time and usage, the measured code would change. Technicians get an early warning for problems that should be fixed before they fail the bus.

If single failure events occur during flight from physical stress or temperature changes, these single events impact the code, thus escape the tolerated margins. These events are recorded for repair. These single events downgrade the avionics communication quality exactly when they are critically needed. Typically such failures would not be traceable when the mission is complete.

Once the mission is done, bus problems are very hard to debug and require special equipment to pinpoint the exact physical location of the problem. In many cases the location is not found because the test is performed on wheels in 1G and in room temperature. Analyzing a recorded key code unveils the location of the problem.

The Tail Code Key technology is seamlessly integrated with Sital’s BRM1553D, ARINC825 and CAN bus IPs and enables advanced maintenance application development for avionic and automotive applications

Sital’s BRM1553 MIL-STD-1553 IP enables obsolete IC replacement at a major OEM integration lab

Posted on by Sital_web3D

Kfar Saba, Israel – November 24, 2005 – Sital Technology, a leading provider of military standard Intellectual Property (IP) cores, announced today that a large Israel based company, will be using the company’s MIL-STD-1553B IP Core for their MIL-STD-1760 weapons bus.

Sital’s BRM1553 core is a second source replacement for a leading Integrated circuit (IC) provider of MIL-STD-1553B devices. Sital has committed to deliver an Altera StratixII FPGA core, which will use the very same Software (SW) drivers, developed for the replaced IC.

The customer developed a PCB board that can accommodate both the 1553 IC AND the required transceivers for the IP core. When the Software integration is completed with the IC device the core will use the same SW drivers and deliver the very same capabilities delivered by the IC device.

Featuring the smallest gate count in the industry, Sital’s MIL-STD-1553B IP core offers highly improved reliability robustness, flexibility and ease-of-use. It is also one of the few IP cores on the market that passed the RT Validation tests, a set of complex qualification tests required to connect to the front-end and ensure complete reliability.
