Hello everyone, I want to use 2 entries of TLB for small size FPGA, Does anyone know what the TLB entry size effect? Is it enough if I use 16MB momory? Thanks...
Hi, We are thinking of implementing and testing modifications to the Leon model (namely the DSU part). I am assuming from previous posts that ISE would be a...

Hi, We use XCV100e Dev. Board from Avnet. When we synthesize Leon with PCI and Ethernet interface using XST and we get the following messages in log file: ...

Hi jiri, We have an OpenCores PCI implementation together with Leon running on an Altera board. We have observed some data being lost occasionally when ...
... We have never been able to solve this problem. It seems to be an issue with the FIFO synchronisation - it depends a lot on the target FPGA and on which...
Hi Jiri, RTEMS applications can be compiled and linked to gcc by the following command: sparc-rtems-gcc -g -rtems -O2 rtems.hello.c -o rtems-hello.exe My...
If you mean the multiplier implementation, than the default is 16x16, i.e. 4-cycle latency. You can change the latency using the -mul option. Jiri. ... -- ... ...
I don't know much about J2ME. If it is ported by using the rtems scheduling interface and turned into a library (*.a), the it should be possible to use the...
I already put that question, but please let me relance it because I got no answers and i am really stuck! How can I create a schematic symbol for Leon in...
