SV TEHS announce major software upgrade for IPJV development boards with embedded virtual machine for Java^TM

The IPJV-ES development board with embedded virtual machine for Java offers an Ethernet based connection to the Internet and numerous interface possibilities to other equipment, include serial RS-232 DTE interface, serializer module with UART, SPI, GPSI and 10BASE-T Ethernet support, 6-channel 10-bit A/D inputs, analog comparator and 16 I/O pins.

IPJV-ES development board based on Ubicom IP2022 Internet Processor with 2MB/8MB RAM and 2MB/8MB flash and include real-time clock with battery backup. Software includes TCP/IP protocol stack, embedded virtual machine for Java, embedded configuration utility and FTP server for remote update of the firmware and user applications. Typical application software includes HTTP/FTP/SMTP/Telnet servers, encryption, security and authentication tools, reporting and alarming via e-mail, remote monitoring, control, management and maintenance.

The software that comprises IPJV runtime environment can be divided into the following categories: native Virtual Machine for Java code, executed directly by IP2022 and resided in IP2022 internal flash and an API interpreted as bytecodes by the Virtual Machine for Java. Application code can be written in Java and utilizes the API to exploit the capabilities of the native runtime and the underlying hardware resources. IPJV uses pre-linked Java applications, which significantly reduce the application start-up times, as no dynamic class loading is required. Pre-linked classes allow VM to execute bytecodes at full speed without delays to constant pool symbolic references resolving.

The IPJVM virtual machine for Java is a clean room implementation that has been specially optimized to run on device with limited amount of internal memory and designed for Java^TM 2 Platform, Micro Edition (J2ME^TM) Connected Device Configuration (CDC) Foundation Profile.

IPJV utilizes GNU Classpath, free core class libraries for use with virtual machines and compilers for Java. The following packages (some with subpackages) are supported: java.io java.lang java.math java.net java.security java.text java.util java.util.jar java.util.zip. This is enough to run many non-graphic programs. Many of the implemented classes are already up to the 1.2 API spec. Some are already compliant with the 1.3 and (preliminary) 1.4 API specification.

With the announced software upgrade IPJV now support javax.microedition.* classes. This generic connection framework provides a coherent way to access and organize data in resource-constrained environment.

A central objective of this design is to isolate, as much as possible, the differences between the setup of one protocol and another into a string characterizing the type of the connection. This string is the parameter to Connector.open(). A key benefit of this approach is that the bulk of the application code stays the same regardless of the kind of connection that is used. This is different from the traditional implementations, in which the abstractions used inside applications often change dramatically when changing from one form of communication to another.

IPJV libraries include implementations for HTTP, Sockets, Communication Ports, Datagrams and Files protocols, LCD user interface, midlets, BASE64 and quoted-printable conversions and more.

IPJV-ES evaluation board offers extremely fast time-to-market solutions for stand-alone embedded tasks such as monitoring and controlling a local device or system, but it is especially useful for different Internet appliances. IPJV-ES can be easily adopted for different legacy devices connection to the Ethernet networks. Shape and specifications can easily be changed to meet application-specific needs.
