DCT To Debut 'Real-World Embedded Java Solutions'
highly practical migration path for electronic OEMs looking to
demonstration of world's first architectures spanning entire embedded
London, UK, October 10, 2001 --- At JavaOne, the Java microcontroller
specialist DCT will launch the software development kit (SDK) for its
Lightfoot core. It addresses a major issue for electronic OEMs - how to
exploit the benefits of Java in embedded systems with constrained memory,
and incorporate legacy code for functions such as protocol stacks.
Providing a software development environment that allows designers to
easily mix languages, the new SDK - in conjunction with DCT's hardware
- will let designers seamlessly execute programs incorporating both Java
and code written in conventional realtime languages like C.
The 32-bit Lightfoot processor core with its customizable instruction
set brings a unique capability to the fast-emerging embedded Java market,
by implementing an architecture that delivers cost-effective embedded
Java systems with very low memory footprints. The high memory requirements
that plague traditional Java implementations are avoided by DCT's proprietary
Java architecture, which delivers the efficiency of code inlining without
suffering from 'code bloat'. The processor also executes a large number
of bytecodes in a single instruction cycle, for extremely high Java performance.
A Lightfoot microcontroller will be demonstrated at the exhibition. A
range of ASSP (application specific standard product) microcontrollers
for target markets is scheduled for release in early 2002.
In addition to the lean Lightfoot core - which requires just 25,000 gates
and is targeted at lower-end embedded Java applications - DCT will for
the first time publicly display a breakthrough architecture for higher-performance
This new solution adds extra logic to a RISC core to optimize it for Java
execution. The design concept - dubbed Bigfoot - typically speeds Java
throughput by an order of magnitude - providing an efficient solution
for volume consumer applications such as home multimedia terminals and
automotive infotainment systems. The example implementation on display
at JavaOne will be based on a commercial core from ARC, developed as a
custom solution for DCT's client Fujitsu.
"The market for embedded Java is developing fast, and evolving into
a number of distinct segments, ranging from low-end disposable computers
for applications such as smart cards, through internet appliances, to
high performance terminals", says DCT's COO, Chris Turner. "It's
clear that OEMs require more than one embedded Java processor - and we
believe our JavaOne exhibit will be the first in the world to support
that need with architecture solutions for both ends of the embedded Java
