JAVA FOR POWERPC CODE

Java byte code is well designed for object-oriented design and dynamic garbage collection. Interpreting byte code is very slow, so a JITC is typically used nowadays, but the JITC slows down first-time execution of all code, and JITCs in general don't produce particularly efficient native code. When a Java program executes, this byte code has either has to be interpreted, or has to be compiled at run-time (with something called a JITC - Just-In-Time Compiler). Java programs get compiled into so-called byte code rather than directly into platform-specific machine language. It helps to understand what Java byte code is: It's an machine language for a (so far) virtual machine. To build a chip to a language seems ridiculous to me. There are some, of course, but I don't think as many as in c, or c++. I don't think most programs for macs are written in java. SAP joined the OpenJDK project last year in an effort to work with developers from Oracle, IBM, Apple, Red Hat, and others on Java innovations as part of the standard open source JDK.I don't know too much about processors, but (to me) it seems unusually ineffecient to engineer a proc to a specific programming language. Oracle declined to comment on the PowerPC-OpenJDK proposal. Plans for the project would include: provision of an interpreter-only version of the HotSpot virtual machine tools and class libraries for AIX and Linux on 32- and 64-bit PowerPC certifiable JDK 7 on Linux and AIX for PowerPC an implementation of the C2 server compiler on Linux and AIX on PowerPC integration of new ports into the main JDK8 and 9 branches. The project will initially be driven by IBM and SAP, said Volker. We strongly believe that fixing these issues will considerably increase the robustness and further portability of the OpenJDK.вЂќ Moreover, adding AIX as a new Unix flavor to the set of supported operating systems will uncover numerous implicit assumptions and shortcuts inside the code base, which only hold true for Linux and Solaris. вЂњAs we already know from past experience, this will unveil all kinds of intricate memory ordering problems. In his proposal, which was floated on an online OpenJDK discussion group, Volker said having OpenJDK on PowerPC would add the first weak memory architecture to OpenJDK, leading to fixes. But these implementations are outdated and/or are orders of magnitude slower than recent commercial JDKs, he said. Or alternative implementations are used such as Harmony. And of course they are highly welcome to engage in the project as well.вЂќД¬urrently, Linux/Power distributions either come with no Java at all, or the users have to get a proprietary Java Development Kit (JDK) from IBM, Volker said.

Linux distributors like Debian, Red Hat, or Ubuntu) will be able to build and provide free and state-of-the-art versions of Java based on the new OpenJDK platform ports. вЂњThe big advantage for the open source community is that everybody (i.e.

вЂњThis reference implementation can then be used by IBM and SAP to provide their commercially licensed Java offerings in much the same way in which Oracle offers its Oracle JDK product based on OpenJDK,вЂќ Simonis said. вЂњThe purpose of this project is to bundle OracleвЂ™s, IBMвЂ™s, and SAPвЂ™s development resources to provide a free, вЂstate-of-the-artвЂ™ Java reference implementation on Linux and AIX on PowerPC,вЂќ said Volker Simonis, a Java VM hacker and OpenJDK evangelist at SAP who is spearheading the project. The ports of Java to PowerPC already exist but would be rendered for the open source realm. OpenJDK serves as the open source implementation of standard Java. The project would provide a full-featured version of OpenJDK for the two platforms. SAN FRANCISCO - Open source Java will be brought to the PowerPC architecture for Linux and IBMвЂ™s AIX OS under a proposal floated lastweek that could eventually benefit the different Linux distributors.
