Altera includes a System-on-a-Programable-Chip (SOPC) Builder [1] along with Quartus. This graphical tool is intended to generate systems with a few mouse...
With the help of SOPC (and the SDRAM controller) a port of JOP for the Altera DE2 board is now available. Both, SRAM and SDRAM (8 MB) are connected. Now it's...
... What were the size of the caches ? Do you know why you can't clock it much higher than the old cyclone ? From the marketing sildes it should be much faster...

... The size of the instruction cache is 4 KB, and the stack cache is 512 Bytes (but it is never spilled to main memory in this version). I played a little bit...
... The ACEX board contains 128KB, 8bit memory. You can use the (new) SOPC builder version of JOP to attach the 8 bit memory. You also have to adapt...
Srry martin for all this work, i hope ..someday i repay u with a pheriperical to your jop library. 1rst: Im doing the serial interfase..and im wondering why...
... no problem ;-) ... As ncts and nrts are less and less supported just forget about them. I disabled the usage of HW-handshake in JOP and down.exe.... BTW:...
Hello all, I am experimenting with the scheduler of JOP, and i have come across a bytecode execution problem that i can not find it's cause. What happens is...
Hello Simon, you got very far with your analyzation of the problem, congratulation! ... The athrow is the cause of the problem. At the moment the Exception ...
Hello Martin, ... I initialize the Dbg class by calling Dbg.initSerWait() . I used this initialization, because the testing application i use is based on the...
Hi Martin, first, answering the question about the memory, the board im using was used with other purpose and the SDRAM was donated (is a board tha was lend it...
The serial interface looks ok. You can use the latest down.c from the actual version: http://www.opencores.org/cvsweb.cgi/~checkout~/jop/c_src/down.c In this...
Hi Simos, ... Both are ok, probably initSerWait is better. However, you can also use System.out. ... How do you get the normal and the corrupted output? That's...
Hi Martin, Thank you very much for your answer and help and sorry for answering so late. I am working full-time and do my thesis at the same time. After one...
Dear, Has anyone ported JOP to XUP board XUPV2PRO ? Would it be necessary only modify the .ucf file of the Spartan 3 implementation ? Thanks. Jardel....
... If you want to use the DDR SDRAM you have to add a controller to JOP. However, the board contains a quite big FPGA. You can start with the on-chip block...
Hi I have some question on JOP. 1>From where the input is passed to JOP? 2>How to write a JOP testbench?Should we force the bits to the input?to see the...
... What kind of input do you mean? As JOP is a soft-core you are free to add any IO devices you like to the design. ... You don't have to. A simulation...
Hello I am trying to get JOP to run on a Virtex 4 (on a ML402 board: http://www.xilinx.com/products/boards/ml402/reference_designs.htm) I adapted the spartan3...
... Very good! Nice too hear that is worked :-) At what frequency are you running JOP and what is the access time of the SRAM? You can probably set some...
Hi all, I am interested in implementing a Java processor in my FPGA. I use a ProASIC3 250 PQ208. Is it possible to implement the JOP in my FPGA? Can someone...
Hello, Please make code available for Virtex 4 device ML402 board. I am working on the ML401 /ML403 board. I would like to try it and if it worked then I will...
Because of JOP's Austrian origins, I have been pronouncing JOP the German way: "yop". But perhaps it is meant to be pronounced the English way? (The English...
The actual Java compiler from Sun (1.5) can now be used with the JOP distribution. On the way to more library functions (I try to add the collections classes...
I'm still fighting with the Java compiler and java.util from classpath. The compiler exception on the collection library happens with 1.4.2 and 1.5. Perhaps...
Hi Trevor, ... That's a kind of funny question ;-) Can you explain (hard in an e-mail) how the English way sounds? There is no 'official' pronunciation of JOP....
... Yeah, that's how I'd pronounce it: like "job". But I thought since you're from Austria maybe you pronounce it "yop". I just wanted to know the "correct"...
