Hi Oleg and Javier, Thanks for the advice. I haven't been able to work on JOP for some months and I didn't realize how much things had changed. So I'm making...

Hi Martin, Everyone, I'm still trying to get some complex Java software working on JOP but keep hitting memory issues. Even with a reduced set, I'm still...
Hi Chris, ... Good that you're still trying ;-) ... That's not enough, you have to change it in several places: See http://www.jopwiki.com/FAQ Basically in...
Thanks Martin, So by changing some of these variables in java or vhd, we make the RAM blocks from JOPizer. If so, where do the new .vhd files go? And will...
... Mmh, the RAM bloacks are not generated from JOPizer. JOPizer links the Java application and checks for the method size. The RAM block (for the stack) is...
The method sizes appear to be fine as JOPizer never gave me any issues (I'm working with CDLC/ MIDP stuff). Sometimes there's error due to jre vision so I'm...
... I don't remember why you needed to 'repair' the tow rams. The cache ram for xilinx (xs3_jbc) uses already a RAMB16_S9_S36, but the size is hard coded to 2...
Hi I tried to port JOP on FPGA board Nexys2 Xc3S1200, but I couldn't make JOP work on it. Does anyone know how to do it? Thank you for your helping....
... No , I just tried to run program HelloWorld on JOP (print Hello World to the console of PC). But it didn't show anything. To make JOP on Nexys 2 Xc3S1200,...

I have other question. Does anyone try to measure clock cycles which are taken by program on JOP in FPGA board Nexys 2 Spartan 3e 1200? I tried to do it but it...

Hi Jardel, you're right that there is a lot of activity on JOP. However, most of the frequent check-ins are not directly related to the core processor. For...
Dear Mr. Martin, First of all, I would like tahnk you for the attention and precious support. Yes, I would like you send me date of that version. Is that...
20080627 was the day after the deliverable, but I'm still not convinced that this is the best approach to work with JOP ;-) Martin ... From: "Ricardo Jardel...
Martin, I understand your point of view. Is there a functional verification setup for the JOP ? Something like regression tests ... Tks, Jardel. 2008/12/13...
We have a minimum of regression tests: test cases under test/jvm and test/jdk and two application benchmarks under bench/jbe. Any contributions to the test...
Hi Martin, Everyone Is there anyway of figuring out how much memory and stack I'd require if I knew the statistics of my program? Class sizes, RAM usage, etc. ...
Hi Chris, the stack size does not depend on the numbers of classes, but on the maximum call depth and the number of arguments + locals in each method. The...
Hi all, I tried to generate mem_main.dat by typing "make sim". But it gives a error. I think it gives the error in the javac command. Do I need the jdk 1.5 to...
