SAN JOSE, Calif. – Angling for a bigger slice of the embedded software, Oracle released a run-time version of Java geared for microcontrollers and a suite of Java services aimed at a broad set of gateways and other embedded devices.
Oracle Java Micro Edition Embedded 3.2 is geared for systems with less than a Mbyte of memory and as little as 130 KBytes RAM and 350 KBytes ROM, especially those based on ARM Cortex-M and Cortex-A cores. The run-time is a variant of the Oracle Java Wireless Client, now also in release 3.2.

Oracle also released a software developer’s kit for the embedded code. The platform targets a wide range of industrial, consumer and energy systems, particularly in machine-to-machine (M2M) applications. Oracle also released a software developer’s kit for the embedded code.
“We believe the next wave of innovation in IT will come in M2M and more devices connected to the Internet,” said an Oracle spokesman.
Cinterion Wireless Modules (Munich, Germany) will demonstrate cellular modules using the code at Oracle’s JavaOne event next week. Separately, Oracle is talking to microcontroller vendors about deals to bundle the software, but does not expect any announcements at show.
In addition, Oracle has released its Java Embedded Suite 7.0, a package containing the GlassFish Web server, Jersey Web services framework and Java DB all based on Java Standard Edition 7. It is available in versions for Linux on ARM and x86 processors.
The suite aims to speed development of embedded systems such as network appliances, medical devices, home gateways and routers and large peripherals such as multi-function printers.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
