ITTIA Embedded Database Provides Data Disaster Recovery and High Availability
ITTIA, a global leader of embedded relational database software, delivers support for High Availability in its leading-edge database, ITTIA DB SQL, so that embedded software developers can accelerate their application development. ITTIA DB SQL High Availability uses replication and online backup to connect databases across a system, ensuring that data is always available.
Highly available systems are designed to operate continuously by leveraging redundant components. For such systems, ITTIA DB SQL is the ideal data management technology, as it creates and maintains redundant copies so that data is always available through any failures, intermittent network connections, and similar unpredictable errors. Since ITTIA DB SQL is a cross-platform database, any combination of hardware can be used to create redundancy, and applications embedded with ITTIA DB greatly benefit from flexibility for handing a wide range of scenarios.
Replication is very convenient to use in ITTIA DB SQL, whether data always moves one way only or is exchanged bidirectionally between many peer databases. Dynamic configuration settings are stored directly in each database file, and can be applied without any restart or reload step. Changes are automatically tracked and can be exchanged with peers whenever a connection is available.
ITTIA DB SQL Online Backup provides a disaster-proof feature for embedded software developers. There is no single way to prevent disasters and the damage caused when data is destroyed. For that reason, ITTIA DB SQL supplements built-in crash recovery with safe backup technology that does not interrupt access to the database, both for reading and writing.
ITTIA DB SQL is a cross-platform product, and supported platforms include Linux, Windows, QNX, and ThreadX. A free copy of ITTIA DB SQL for evaluation is available at:

testIDEA: RealTime-UnitTest from iSYSTEM
testIDEA deals with the smallest testable parts of an application, which is usually a function. It's greatest value is in early detection of problems, because finding the error in the integrated module is much more complicated than finding the same error in an isolated unit. Furthermore, fixing small problems every few hours takes less time than fixing huge problems just before the deadline.
To perform Embedded Software Tests, iSYSTEM provides testIDEA. It expands iSYSTEM’s debug and trace tools for software development (which encloses the complete iSYSTEM Blue Box hardware) and allows the execution of test cases and test vectors on the real customer hardware without code instrumentation – other tools usually instrument the code.
Primarily testIDEA is a free and open programming interface (API) that is completely integrated in winIDEA. With that API set one can write test applications/cases but also automatically execute them on customer’s hardware connected by iSYSTEM tools. Test applications, test cases and the accordant test reports can be written in many different programming and scripting languages (Python, Java, C/C++, C#, Perl, TCL…).
testIDEA also includes an interactive editor for generating test cases and test reports that can be directly called from winIDEA. With that GUI test cases can be created without any programming know-how. testIDEA stores the test cases as YAML (YAML Ain‘t Markup Language) files which is a description language similar to XML, but easier to read and to process in other languages. E.g. YAML files can be included in Python exactly as they are and therefore they are reusable in an executable mode.
testIDEA is used within the familiar development environment directly at the developer’s workplace. A developer can accomplish unit tests (tests on the smallest, testable entity) in their different variants like Black Box (function code is unknown) and White Box (function code is known, code coverage) test.
The major advantage of non-instrumented unit tests is the fast turn-around-time because the tests can run without compilation, linking and download. In addition no test drivers are needed and therefore no additional resources are used on the target system. Functions like tracing, profiling and code coverage analysis can be integrated into the test cases. This expands the operation area of iSYSTEM test technology from unit testing to integration and system testing.

Unicoi Systems and DS2 Power Room-to-Room Streaming HD for Consumer Entertainment Devices
Fusion TCP/IPv4/IPv6 Embedded Networking Stack and DS2 Powerline Networking Devices Revolutionize Digital Home and Gaming Experience
Unicoi Systems has announced the implementation of Unicoi's Fusion TCP/IPv4/IPv6 in the next generation of digital home networking solutions from DS2. DS2's Powerline Communications products, running Fusion TCP/IPv4/IPv6 Dual Mode Stack, facilitate whole-home networking through existing home wiring.
Unicoi Systems' CEO Greg Coonley said, "Unicoi is enthusiastic about being part of a revolutionary breakthrough in the digital home and gaming experience. We are pleased that DS2 chose Fusion as the high-speed networking solution for DS2's UPA Plug tested powerline communications products. We look forward to working with DS2 to further improve data throughput for Powerline Communications' customers including D-Link, NETGEAR and Texas Instruments."
Eivind Christensen, Product Marketing Manager at DS2, said "Unicoi Systems has a long history of delivering quality embedded software. The Fusion product family is a very comprehensive suite of network connected software for a variety of embedded applications which is why we chose to run Unicoi's Fusion TCP/IPv4/IPv6 Dual Mode stack in our powerline communications chipsets for digital home networking applications."
DS2's 200 Mbps Powerline Communications chipsets, featuring Fusion TCP/IPv4/IPv6, deliver room-to-room HD streaming that allow consumers to instantly connect devices like computers, HDTV's and gaming consoles to each other over existing home wiring. By simply plugging the DS2 based powerline networking devices into any electrical outlet around the home, the wires in the walls network the devices together to deliver high-definition media streaming, online gaming and other next-generation digital home applications including networked security cameras, and audio and digital photo file sharing.

Performance Enhancements Make Fusion Stack Unparalleled
Unicoi Systems has proudly announced release of their Fusion TCP/IPv4/IPv6 Dual Mode Stack version 8.6. This release was motivated by the drive to increase Unicoi’s performance lead over lagging, less adaptive solutions from 'Gold Rush Era' competitors. Now, the most trusted embedded TCP/IP stack in the industry is even faster.
"Despite the recession, Unicoi Systems is still experiencing growth due to demand for an inexpensive, highly portable TCP/IP stack that exceeds the performance limitations of larger, less portable solutions from entrenched real time OS vendors. In keeping with our overall product strategy of ultimately finding ourselves only competing with our own incumbent solutions for top seed performance benchmarks, Unicoi offers an alternative to single source options with outdated IP and bloated pricing models from the 1990s", says Greg Coonley, CEO of Unicoi Systems.
Noteworthy performance gains in TCP transmit and receive are the results of many man-months of effort by Unicoi’s highly experienced engineering team. Fusion TCP/IPv4/IPv6 8.6 boasts TCP transmit performance that averages 25% higher than previous versions with peaks in excess of 40%, depending on the transmit buffer size. On average, the TCP receive performance is improved by 20% over Fusion TCP/IPv4/IPv6 version 8.5 with peaks at over 30%, depending on the size of the receive buffer size.
To run faster, the Fusion stack has to run smarter, which is why several new features are part of version 8.6. A new socket option is provided for tuning TCP performance by allowing the TCP ACK strategy to adapt to the saturation of the socket receive buffer. Also, a new set of driver API functions allow developers to create a pool of reusable message buffers for receiving packets from the network. Additional changes in the core stack allow drivers to pass packets received from the network to the stack where the actual packet data is contained in a buffer allocated from a different memory space than the Fusion stack's own heap.
