Java Controller accelerates CPU intensive tasks.October 25, 2011 -
Based on Imsys native mode IM3910 Java processor, SNAP Stamp(TM) contains full TCP/IP stack, CLDC environment, Web/FTP/Telnet servers, device drivers for I/O interfaces, and command line interface. Java applications run natively on processor without compilers or delays from Java byte code interpretation; users can copy Java class or jar files over and run them. Rubus(TM) RTOS is also standard, in addition to fail safe flash file system with wear leveling and power fail recovery.

SNAP Stamp(TM); Java Controller Powering the Internet of Things
Compact Low Power Module - A Complete Platform for Java Applications
This is the smallest and most cost efficient hardware module in Imsys' SNAP family (Simple Network Application Platform). It builds on previous generations of the SNAP FX (small mezzanine) and SNAP Classic (SIMM72) modules. Featuring the newest Imsys processor generation and providing full access to the processor's features, it's ideal for OEMs needing a powerful computer on module for minimizing time-to-revenue.
The SNAP Stamp is based on the Imsys native mode IM3910 Java processor. This allows user Java applications to run natively on the processor without the slowness of Java byte code interpretation or requiring costly special compilers - just copy your Java class or jar files over and run them. Firmware and application software can be uploaded and managed through the network connection, including remote software upgrades. It contains a full TCP/IP stack, CLDC environment, Web / FTP / Telnet servers, device drivers for various I/O interfaces and an easy to use command line interface. Included standard is the Rubus(TM) real-time operating system that is well proven in safety critical applications and the fail safe flash file system with wear leveling and power fail recovery. The embedded real-time Java environment greatly accelerates development and eases deployment.
Java class files generated by any Java IDE (Eclipse, Netbeans) are directly executable on the SNAP Stamp. Development kit hardware and reference designs are available. The Imsys Developer (a complete Windows-based IDE) can be utilized for hardware debugging and software development in Java, C and assembler, with breakpoints, dynamic variable inspection, and single step debugging at all levels.

*) Optional, RFQ for volume orders
The microcode inside the core controls the processor logic and hardware resources and provides the abstraction layer used by the software.
The architecture enables acceleration of CPU intensive tasks by orders of magnitude. Functions like jar file unpacking, garbage collection, bytecode interpretation, encryption, Ethernet MAC, audio playing, and video display are included in the internal processor microcode. The processor can therefore handle combinations of tasks that would otherwise require much more silicon and/or power consumption.
