Hi Trevor, ... Of course I agree that 100 MHz is enough for some embedded systems ;-) And it's not that bad for an FPGA based processor. Only very FPGA ...
Hi, ... I found a different paper that compares FPGAs and ASICs. For the die area, a factor of 17 to 35 was measured, for the critical path delay a factor of...
Dear, I've synthesized JOP with bgx_shell from cadence. In fact, i was interested in get it syntehsizing and I set the speed for only 50 MHz. I will re-try and...
Hi Wolfang, ... thanks for pointing it out. That was actually the paper I wanted to refer. So my 10x was too high. Assuming JOP in Virtex-5/Stratx-3 at 200 MHz...
Hi all, as some of you already know, I'm at the moment working on the reference handbook for JOP. The intention is to publish a 'real' book that is available...
... I will do a review. ... Something you might consider is publishing through Lulu: http://www.lulu.com/ You can publish books there that are as "real" as the...
... very good - the first volunteer ;-) I assume I have your address and will send you the handbook. To others: I still have some more to give away :-) ... ...
Hi, It appears that the JOP build script is set up so that only the classes that are accessed by the target application are compiled. For example, if you...
... Yes, that's the intention. This minimal class file compilation uses the intelligent compile of javac that compiles all dependent classes from a single...
... The problem for me, and probably for future authors of JOP-based tools, is that there is a need to process more than one application at a time. There may...
... By re-run the JOP build you mean only compiling the Java files, right? You only have to call the make/Ant target java_app/java-app. ... You don't have to...
... Right, just the app part. ... Wow, I can't believe I didn't think of that. Sometimes I can't see the forest for the trees. But that's another reason I...
HI, I'm a student of University of Catania (Italy). I downloaded the last recently version of jop, from http://www.opencores.org and attempted to build the...
... The jop.ucf does not only have to fit to the FPGA type, but also to the board. What kind of board do you have? If it's the Spartan 3E starter kit there is...
Hi JOP'ers, The error I have is when ModelSim starts up: # do sim.do # 1 # .main_pane.mdi.interior.cs.vm.paneset.cli_0.wf.clip.cs.pw.wf # ** Error: (vish-4014)...
In the current version of JOP I cannot see those errors - just checked. Looks like you have an older version. However, you can ignore those errors from...
Hi everyone, As you might now there is a hardware FPU, developed by Jidan Al-Eryani (http://www.opencores.org/projects.cgi/web/fpu100/overview), available as a...
Hi Martin, JOP'ers, I'm trying to see if JADE (an agent middleware) will run on JOP. It works in ModelSim but I have the feeling that I'd need to let the...
... Well, I am not sure when/if I'll get to read all the way through this much less post a review, but I'd like to just say that this is very useful for...
Hi, I am new to fpgas and jop, but we want to get jop running so we can leverage an app thats already done in java. I have a terAsic DE1 board with a Cyclone 2...
As a test, I ran the standard Makefile entry versions (for P1, P2 and P3) for HelloWorld. This worked fine. But when I edit P3 to change what program to load...
Hey all, Check it out: Bluetooth for JOP! http://blueonjop.sourceforge.net/ I can't believe this hasn't been mentioned here yet. It's exactly what I needed for...
Hi Joe, the DE1 board looks very similar to the DE2 board - same features, especially the same SRAM. I would start with the Quartus project altde2sram, change...
Hi here i am trying to compile the source of JOP, on doing this i was stuct that i didn't get all the source files like my top file is jop_b5x300.vhd ...
Yup, very weird. I try "make jsim -e P3=Test" which fails. Yet "make jsim -e P3=HelloWorld" works fine. I think it could be my makefile. I've included a lot of...
