Hello All, I am implementing the JOP on to Xilinx Virtex-4 device. The board I am using is ML401 developement board from Xilinx. I can download the program...
When I was testing on the Spartan 2, I created an asm file called testmon that allowed me to communicate with the device and test the uart as well as the...
... So we would have finally graphics on the JOP ? Great ! ;-)...

Hello... well i've already talked to martin once about my interest in using JOP at my research...but unfortunately, due to some project restrictions, i am...
Hello Alexandra, ... That's an interesting information. It explains for me the low cycle count of some operations on FemotJava (e.g. getfield). FemtoJava is...
Hello Martin! :-) I am really happy to know that those limitations don't existe for jop. (or at least they are not SO limiting) :-) But some other question is...
Hi, I have a doubt as to how are the above bytecodes implemented. Going through the code, I found that you are not using the objectref in the implementation of...
... Ed, thanks for your testmon.asm and the hint. As there are so many port efforts of JOP to different FPGA boards on the way I will start a document to...
Hello Alexandra and all, ... This should work on JOP. I can offer you two ways to verify that your application will run on JOP: a.) You can perform a quick...
... I used a, very efficient, shortcut: On monitorenter the interrupts are disabled and on monitorexit they are enabled again (with a counter to detect nested...
I would suggest looking at using wishbone to interface JOP to the memory controller. I've just uploaded a vhdl file to the files section that I've used for...
... Using the WISHBONE interface as memory interface is a good idea. However, I'm not shure if we will need one more cycle for a memory rd and wr due to this...
Hello, my name is Christoph and I am a student from Austria. I work on a projekt about JOP. My project is to get the JOP onto a Xilinx Spartan- 2 board from...
... I would like to have a single clock for JOP and the WISHBONE busses. Systems with a single clock are easier to handle. ... Yes, both are masters. However,...
... You loose a LOT of performance on the SDRAM, if you not clock it faster, and as fast as possible. And, somehow it makes sense to have even three clocks...

Ideally, everything should run at the same clock speed, but it's often desirable to be able to allow the different cores to run at their optimal speeds. If...
... I don't buy an additional clock for the IO (except it's some kind of fast serial link with Clk_io > Clk_cpu). ... It's not about simulation. If you have...
Hi Ed, I did find the testmon.asm file. What is the command to run this file. After I configure the Xilinx FPGA (Virtex-4) device what I should do to run the...
Hi Shan, please read my posting on this topic 3 days ago. I've added two make targets and a description to the build document especially for you to help you. ...
Shan, Can you send me your JOP project up to this point for the virtex 4? I would not mind looking at it and seeing if I can help at all in getting it to...
Hi Brett, I need to ake my manager if I can send the project. I am working in company. I have to get the permission before I can send anything. In the mean...
No I have not done it on the ml403 board yet. I was looking to do so sometime soon and thought if you had it started for the ml401 I might be able to help out...
Hello: I am working with JopSim I want to establish connection between two processes on one PC. So the processes can exchange messages via Udp. I have a...
... unclear ... other ... Hi Anna, I have just started with this as well. You can use http://com0com.sourceforge.net to establish a pair of COM ports. I think...
Hi Brett, You welcome, Yes I did started and I can load JOP onto the ML401 board but I still have issues. In addition I did the verification using ModelSim MTI...
Hi, Martin and I started working on getting JopSim to work over SLIP running on the comOcom virtual nullmodem. It was challenging. But it works on a "real"...
Dear Rasmus, thanks for posting the changes. However, the files are not usable (at least for me) as some constructs are substituted by smiley pics! So please...
Hello: I am working with JopSim I have a question: is it possible to make two processes run on one PC and comunicate via Tcpip and not via serial ports? I...
