PCI driver in Linux is pretty easy to write. the problem with pcie is that it's difficult to debug the physical layer unless you have very good tools. I2S is actually a super easy way to move a lot of data and you can get parts with pretty fast I2S channels. if your signal rate is higher, for higher rates usb is probably your best bet.

better than accumulator architectures, I guess. but seriously, use a cortex M0/3

suffix posted:is codesourcery still a thing? yes. ARM hired them to make GCC not terrible for ARM targets. they've made some good progress. eschaton posted:how's LLVM/clang as an embedded compiler these days? should have pretty good ARM support. it is the default compiler for iOS so it's pretty good at arm (and the best arm64 compiler now that Apple open-sourced their backend). it took them a long time to figure out stuff that embedded targets need, but now they seem to be on it so they won't blow your stack up or break cortex m by putting in unsupported op codes. although they do have a knack for screwing up inline asm. It's probably my compiler of choice unless I'm really pressed for space.
