Re: [Flashforth-devel] PIC32 in DIL28

[Mikael N. <mik...@pp...>]

I looked shortly at the MIPS CPU last year.
It seems to me that making a subroutine call and returning
is cumbersome in MIPS.
You had to write to a linkregister to be able to return from
a subroutine call. Also It was not clear to me if the
retrun stack is managed in HW.
Also you had to fill some delay slots with nops after the subroutine call.
MIPS is perhaps better suited for a threaded Forth instead.
