I'm afraid, the server-space is not
large enough to list all of them, so here are just some:
I designed it to offer a low cost FPGA board with high speed interface
to an external SDRAM, in particular to a multi-bank SDRAM cluster. Also
a separated data and program interface was important.
I stopped working on it, because there is way too much work involved to
provide it to the masses as a low-cost FPGA board. I hope there will be
a professional low-cost FPGA board with RLDRAM support, soon.
I designed a plug-and-play system, which has a higher density than the
PMOD system. Unfortunately the connectors are not stable enough to be
used in the field.
I designed a Cortex M3, but then the RISC-V sneaked around the corner.
the Cortex M3 design for comparison, but I doubt, that the RISC-V ISA
is more efficient.
