The future of 32-bit Linux

Due to plentify block ram in most modern FPGAs, an MMU implementation on an FPGA can actually be pretty cheap.

At the moment a <$100 USD FPGA dev board with <1 gigabytes RAM can be purchased that a 32bit Linux + MMU is *significantly* smaller and faster than 64bit. Due to the newer FPGAs mostly been focused on the datacenter use case and thus in the >$500 USD per FPGA IC, I don't see this changing for at least another 5ish years.
