... Yes, that's just the newer version of the Xilinx Starter Kit. One has to attache a DDR memory controler to JOP. As I see the original Logic Analyzer was...
You mean a mixed LEON/JOP system where LEON does the C code and JOP runs Java. That could be a fun system. I started with an AHB interface for JOP to test the...
That does sound fun. I'm definately interested in doing this (and any useful pointers as to what steps need achieving via email would be great). Or is it just...
Chris, ... The AMBA interface is the main hardware related change in JOP. Attaching two AMBA masters to the grlib arbiter should be straight forward. The next...
Hi Martin, That part seems straight forward enough (and very interesting!), but how would you run an operating system on top of that to switch between the...
... What do you mean by switch of the cores in RTEMS? I think both cores run parallel: C apps are scheduled by RTEMS on the LEON and the Java application runs...
Hi everybody, I ported DES to run on JOP. The resulting version is based on the implementation found in http://www.herongyang.com/crypto/des_implJava.html ...
Hello everybody, I just included a new description of a project called JopVga on the JopWiki Site: http://www.jopdesign.com/wiki/index.php?title=JopVga The...
Two Students at TU Vienna (Alexander and Peter) have designed and built a very nice board to interface JOP with the LEGO Mindstorms system. Take a look at ...
... Nice project. Perhaps someone with a Xilinx Starter Kit (the old one) can try to get this running. AFAIK you need following changes: * Get a Xilinx (or...
Hi,all My project is porting JOP to the Xinlinx Spartan-3A My changes are following: 1.Add a internal RAM ('cause S3A doesn't has SRAM) 2.modify the memory...
... Sorry for the delay . .. It was easy to port it. I just added some methods to the String class that were missing and replaced some call for data conversion...
... Can you say which methods where missing? Or provide a patch so I can integrate your changes in the JOP CVS. ... What do you mean by more performance? ...
... You will not have too muc fun with internal RAM only. From you numbers I gues you configured 2^12*4 Byte = 16 KB RAM. The footprint for a 'hello world' is...
... route ... Hello,Sir I didn't change the source code for any signal about "*rx*". And I have traced the source code. However,I have no idea what should I do...
... specifically ... I just remember substring, but there were one or two more. They are in a folder in the group in a String.java file. ... performance. ... I...
... So you mean optimizing the DES code. I had a quick look at it some days ago and it is very non-optimized in my opinion. Too many method invocations for...
Hi all, at the moment only a stop-the-world garbage collector is enabled for JOP. I'm currently testing a concurrent version of the GC. As this version of the...
Hi,Sir There is no problem on Spartan-3A. It's OK! I make a stupid mistake. That is my Cygwin have no "gcc"!!! When I execute jopser, some VHDL code didn't...
Hi all JOP users, I just wanted to inform you that all projects have changed a little bit because the component sc_cnt was replaced by sc_sys. The change was...

... Hey !! I was thinking on that too!!. I just took the easiest approach and made independent schedulers for each processor. But I think that the code in...
... The changes in sc_sys are just for booting the CMP. A single 'run' bit that is set by CPU0 and read by CPUn. It has at the moment nothing to do with...
... My implementation is as follows: 1)A owner_id variable on the object to store the id of the thread. 2)A count variable in the same place to know how many...
Hello, I am studying JOP and I like to try develop one application board (JOP) to communicating with the network. This application only get one information of...

The Cyclone board are specific for Java (JOP)? What are the pre- requirements for use Java in these boards?? Regards. ... (JOP) ... one ... application....
No, it's not specific for JOP. I've run on it also: NIOS, LEON, and mlite (but mlite has some bugs). You should use JOP for Java on this board ;-) An...
