Mmm, iam using FPGA emulation board ML402 with LEON3 cpu and |
38 |
Gaisler's IP-blocks. There is no FPU, because FPU is not for free:) |
39 |
I have some old splack distribution (from older colleges, i don't know |
40 |
where they find it:) Splack runs fine, but there is no toolchain and |
41 |
that's why it is hard to install modern software on top of it.. |
