right, i was wong.
it turns out that PIC32 is a low-end MIPS core with a boatload of
PIC-style on-chip peripherals and no PIC core anywhere.
still, it doesn't have any external bus interface (no, GPIO pins
doesn't count. i've done that on smaller PICs, but it makes external
memory look like storage devices, not RAM); so any port would be
limited to what inner memory can hold.
OTOH, MIPS is a real 32bit ISA, targeted by real C compilers (gcc
among them). In fact, even i own a MIPS-based router running a full
Linux (OpenWrt), complete with a Lua interpreter, and i consider
myself quite lacking gadgetwise.
