Idea: Add lots of tiny CPUs, say Cortex-M0, to FPGA fabric as hard IP. Quick estimate says 2x M0 are ~= size of one RAMB18 on same process

@oe1cxw@azonenberg I wonder how a 6502 core would do (I like those as a compromise between Picoblaze and a full-blown RISC CPU)?
@cr1901 @azonenberg The 6502 had 3510 NMOS transistors and 1018 pullup resistors.

@cr1901@azonenberg Or in other words: the 6502 had fewer transistors than the PicoRV32 has gates. -
@cr1901@azonenberg But then, most of the PicoRV32 gates are related to the register file and the 6502 had no register file. - Show replies
