New embedded Java-based controller released

Started by Alberto Torrecillas September 7, 2004
Snijder Micro Systems just announced the public release of the second
generation of their Embedded Java� Controller (EJC�) product line,
codenamed EC200. The EJC is a family of embedded controllers that
implement a full-fledged Java platform for network-enabled and
standalone applications.

The EC200 sports a 32-bit 74 MHz ARM720T CPU and along with a slave
PIC16LF872 microcontroller. The module can have up to 64 MB of SDRAM,
16 MB of NOR flash, and 256 MB of (optional) NAND flash. Integrated
interfaces and onboard devices include a 10BASE-T Ethernet controller,
23 digital I/O lines, 3x 10-bit analog channels, dual 16550 class
UARTs, dual fast-mode I2C master, Dallas 1-wire master, graphics
LCD display i/f, an ISA-style expansion bus, etc.

The software integrates Tao Group's intent� technology, featuring an
advanced Real Time Operating System and a Sun-certified Java Virtual
Machine (JVM) that combines unrivalled performance with minimal
footprint, due to the tight integration between kernel and JVM and to
the advanced translation technology which compiles all Java bytecode
to native code before execution. Java APIs are provided for efficient
access to hardware resources such as I/O ports, system memory and
memory-mapped devices, interrupts, and onboard peripherals. This
allows developers to adopt an all-in-one approach where applications,
system components, and even device drivers can be written entirely in
Java, without compromising on flexibility or performance.

More details can be found in the EJC website:

At the risk of starting a flame war: what is the advantage of such a platform running java instead if C? I mean, java applets in a web browser I can understand. But java on a not-java controller, which has to compile in time or interpret the p-code..... Meindert

Java programmers are cheap and plentiful and if kept distant from the hardware don't need special training. Much like the art-school advertisements: "Anyone who can write can draw!".

Depends. Which do you prefer? You might use Java, because it has (add a feature here, like "GC"). You might prefer C, because it has (add a feature here, like "no GC").

The device might be connected to some other system running in Java and you want to use e.g. RMI. Or maybe you want to run same binary in several targets and want to avoid recompiling. Or maybe you have nice development environment and want to use that. There are millions of reasons to pick a language and avoid another. Being interpreted/JITted might be reason to avoid, or it might not. JIT does not (necessarily) make a language that much slower or bigger to mean anything to you. Or it might. And then there are the religious reasons ... I have no preference, but I am happy to have choices. -- @jhol

I guess the benefits are just the same as for desktop and server-side applications: - Increased productivity: * Lots of good dev tools * Lots of high level APIs * Higher level language * Fully OO - Leads to more maintainable code, less bugs. - Portability -- can migrate to a different platform later. - You automatically get all those nice Java things such as networking, security, remote class loading, etc. without having to do all the work yourself :) If properly implemented, the developer should not need to care whether the platform is translating bytecode to native code before execution, as this process can be completely transparent..
fuck Java........

now, yes, i top post................ you've already seen the original poster
about 5 times, need you see it again?

This might start a flame war, but I have some questions about OOP in
general.  Here are the usual compliments, and my argument to them:

1.  It reduces development time.

Bullshit!  It increases development time, as the OOA has to precede the OOD.

2.  It enhances code reuse.

Bullshit!  How many companies have you worked for that has ever reused
anything?  And even if they did, you still have to redesign the heirarchies,
etc.

3.  It makes debug easier?

Duh, are you really a programmer?

4.  It is an accepted fact that OOP is better.

granted

5.  It is better for a team of engineers working on the same project!

granted

... snip ... Please do not toppost. Your answer belongs after, or intermixed with, the quoted material AFTER snipping those portions not germane to your reply. Yes, you are allowed, in fact encouraged, to snip. That is one of the important points. Top posters tend to get ignored, especially in the comp.* hierarchy. -- "I'm a war president.

so, CBFalconer just taught me how to post newsgroup messages............
thanks bro, i don't think i had a chance without you...............

Has someone access to this system? I would be interested how this JIT solution on a ARM compares to a 'real' Java processor at about the same frequency. I'm actually collecting/writing testbenches for embedded Java and can provide them for a quick comparison.
