I have a problem about memory initialization of JOP processor  When i run any program such as QuickSort or MatrixMultiply, PC and IR for both of them are...
Dear all, I need to run some programs in JOP and simulate it with modelsim. when i run a program and simulate it and see wave window, IR and PC is equal to...
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...
Hi, when i run helloworld on JOP, i see "JOP start" message but i don't see "Hello World from JOP" message. also, when running another program PC and IR don't...
Hi, when i run helloworld on JOP, i see "JOP start" message but i don't see "Hello World from JOP" message. also, when running another program PC and IR don't...
Hi Somayeh, congratulation, you got JOP running in the simulation. "JOP start" is only the first message that is shown. In ModelSim you have to simulate up to...
Dear all, Â JOP simulation by Modelsim is very time consuming. Â Is there a way to decrease its simulatiion time ? Â Best regards, Somayeh Dear all, JOP...
Hello! I wrote sc_mem_if for Xess SDRAM, but I have not confidence that he fully working. Although testmon and jopser worked with him ok. I have a problem with...
Hi Oleg, I would suggest that you try out some programs with one CPU. Then you can be sure that the SDRAM controller works fine! Furthermore, you can go on...
Hi Somayeh, I'm sorry to inform you that there is not much you can do about it. You could try to remove some signals of the wave window. Consequently you don't...
Hi Oleg, I found a little problem in your SDRAM controller that may work with the uniprocessor but surely won't work in the CMP version with the arbiters. The...
Ok, I thought about it, but read simpcon.pdf (page 5) "Slaves, that don't know in advance how many wait states are needed for the transaction can produce...
Hello! You were right! I remade a bit and everything worked (with sc_arbiter_fair) Suffice it to add rdy_cnt = 1, ie, 3 .. 3, 1, 0 MatrixBenchCMP.jop JOP start...
Hi Oleg, oh yeah, congratulations from my side!!! I hope it feels great to run a CMP version of JOP!!! :-) I would suggest to add the 2 into the generation of...
By the way: I would be curious if the benchmark results are getting better! Please, post the same results as you already did after adding the 2 in the rdy_cnt...
Hi Dear All,  I search in JOP handbook but I can't find output pins of JOP processor. is There no any datasheet for JOP?  Thanks, Somayeh.       ...
Somayeh, From software point of view, pins are accessed by The methods Native.rdMem() and Native.wrMem(). From hardware point of view, they´re implemented in...
Hi Oleg, ... that's interesting! I've never tried to use the Xess SDRAM controller. We could try it out on our side with an Altera board (DE2). Can you post a...
... mmh, from the definition of SimpCon this is correct. It has to decrease monotonic, but each value can be ommited. At page 4 of the paper it is stated: ...
Hi Martin, ... I use version 1.6 from http://www.xess.com/ho03000.html I beginer in the FPGA - can not use pipeline of then controller for reading 32 bit words...
Hi Martin, ... I think so too, but sc_arbiter_fair does not work when cnt = 3 ... 3, 0. Only if 3 .. 3, 1, 0 sc_arbiter_fixedpr work with 3..3, 0, but not...
