Hi, I'm trying to understand data caches in JOP and other Java processors. Consider, for example, the following code: class MyClass { int primitiveField; int[]...
Hi Trevor, ... Almost correct. Yes, data on the heap is not cached. It is loaded from the SRAM and not from the Flash. As you have developed a WCET analyser...
Dear Mr. Martin, ML-403 is a board very similar to ML-401. In fact, the PCB and almost all components are the same. The real difference is that ML-401 has a...
... I thought perhaps that was a worst-case time for data cache misses. Unlikely, but I wanted to make sure. ... Thanks for the link. Wolfgang notes that the...
... 3 , the problem is that : I don't know nothing about Quartus and Jam; I don't need Cygwin because I work on Linux CentOS 4.6. I've been working with ISE...
Hello! I also try to start JOP on ML403. I have nothing at all happening on the serial port. Tried jopser, blink. Can you help? Could send .bit file? ... ...
I use ant to build jop under Linux. "jopser" compile ok, but does not work (I have ML403). I can not compile the "blink", help pls. ant jop-blink-test ...
Dear Frineds. I want to implement a Hardware JVM over a RISC processor for my MS thesis, I dont know whether I came to a right group. Please guide me. Erfan...
Hi Erfan, ... its a little bit off topic for the group, but interesting. What do you want to achieve with a hardware JVM on a RISC? I can imagine to add object...
Hi, In the CVS repository, there are 3 quartus projects using JOP with the DE2 board: - altde2 - altde2cmp - altde2sram What is the difference between them ? ...
... that's one to use with Quartus SOPC builder to use the Altera SDRAM controller ... a JOP CMP version with 3 CPUs, using the SRAM ... A 'plain' JOP project...
Hi, When we tried to build JOP with this project file, a compilation error is obtained from the «jop_256x16.vhd» file. This file uses the «sc_mem_if»...
Hello! I'm trying to run JOP on two different cards. Used Spartan3E (from starterkit.ru) and Virtex-4 (ML403). Results of blink and testmon same. blink gives...
Hi, there have been some changes in the memory interface that introduced a bug for longer wait states. It's now corrected. Please checkout the current version...

Hello Somayeh, It is essential to give us a little bit more information when posting to this group. When did you check out the latest version of JOP? I just...
Hello, I don't see "JOP start" message and i don't see "Helloworld From JOP" message after running HelloWorld.java. Would you please explain for me all...
Okay, then something goes wrong! ;-) I would suggest that you have a look into the JOP handbook [1] p.18, where the simulation process of JOP is explained. To...
To make some things clear: - Quartus II Synthesis tool is for generating real hardware in programmable logic - ModelSim is a simulation tool using hardware...
