Hi Jiri we tried to do a performance-esstimation of leon2 using the free tsim-leon3-evaluation-software. We compiled a complex software-routine and run it in...
I write for first time, and i don't know a lot about how this works. If anyone can answer I will like to know how to get the vhdl source code of leon2 and...
TSIM for leon3 has rougly the same timing as TSIM for leon2, so the results can be applied to a leon2 system. Note that the timing accuracy for TSIM leon2/3 is...
Thanks for your answer, jiri. I have to be more precise. I'm specially interessted in the number of cycles which have been estimated by the profiler. Are the...
The profiler gives you a statistical value based on the number of sampe points. For higher accuracy, you need more sample points, i.e. run you application for...
IO tried to make a compilation with rtems after quite a long time and now everyt time I call sparc-rtems-gcc I get the following message: sparc-rtems-gcc:...
Hi Jiri, In the past I've used Leon2 environment. Today, I'm trying to evaluate Leon3 environment and make a configuration to load it in our own (private) fpga...

I suggest you start with the leon3mp template design, just do a 'make' in its directory and you will get a menu of possible actions: $ make interactive...
Hi, On the LEON web site, it lists that the LEON-3 core runs at 400MHz in 130nm ASIC and up to 125MHz in FPGA implementations. What are the details behind...
To verify the FPGA number (125 MHZ) is fairly easy. Select a template design in grlib (e.g. leon3mp), choose a fast virtex4 device as target, and run the...
Hi, Jiri: According to the description of co-processor interface, the co-processor seems like a pure execution unit to execute co-processor related ...
The co-processor instructions are fetched and deceoded by the normal pipeline, so they will be stored in the icache as any other instruction. Regular...
Hi all, I am using leon2-1.0.29-xst. Can I disable both instruction and data cache but enable the two local rams for program and data section. And how to make...
Hi Jiri, Kernel 2.0 supports for CAN4Linux in Snapgear. But why it was not ported to kernel 2.6? I know that the latest version of CAN4Linux support Kernel...
Hi, I'm using Grmon 1.1.6 pro with the DSU backend and Leon2 1.0.12. When booting from the internal prom how do I tell what leon detected for external memory. ...
Snapgear is based on kernel 2.6.11, so I don't see any reason why you should not be able to add the CAN4Linux support to it. If you do, send me the patches and...
Hi, I'm developing an application with eCos running on a SoC that has a Leon core. So far, everyting has been fine. But now we have integrated some standard...
Leon2 version 1.0.31-xst is now available for download from www.gaisler.com. ... LEON-2 VHDL model version 1.0.31-xst, released on 30 November 2005 * Minor...
Hi Jiri, I cannot run succesfully the GRLIB system test in the leon3-gr-pci-xc2v3000 design To compile the leon3-gr-pci-xc2v3000 design using modelsim (version...
Hie Jiri, I am using leon2-1.0.30 on an Altera Stratix board, with Snapgear- Linux running on it, which I must debug at C source level. The problem is that I...
Hi! I've tried setting up Eclipse to work with tsim-eval as described in http://www.gaisler.com/eclipse/cdt/cdt.html, but I didn't have much luck with starting...
This is fact a gdb-6.3 problem, the older 5.3 works OK. I will investigate how to fix it. As a temporary work-around, you can use sparc-rtems-gdb from the RCC...
