There are also database programs that want to mmap() large sparse files. To some extent that is where the pressure for 64bit addresses comes from. While (I think) most of the current riscv systems are 'toy' ones there are definitely press reports of some quite high power systems. I suspect they are less 'toy' than the Altera (Intel) Nios processors we use on out fpga - you can run linux on the Nios cpu, but you probably don't really want to do so. Better to find an fpga with a 'proper' ARM core in the corner. David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
