My question was actually aimed to Hector Posadas or Javier Castillo and I'm
aware of the OpenRISC 1000 spec vs implementation like OpenRISC 1200. Let me
rephrase the question then.
Hector: What are the specific features of the OpenRISC-implementation that
differ from other OpenRISC implementations?
BTW Damjan you description above might be good explanation at why the name
"OpenRISC 1000" is probably a bad name for a general API when the implementation
instances are calle "1200", "1500" etc. Calling the API/defintition something
distinct (x86, IA-64, SPARC V9) and the implementations something else
(PentiumIII, Itanium, UltraSPARC IIIi) makes for less confusion.
I suggest that you at least drop the "1000" just having OpenRISC, change the
number a more normal version numer (1.0, 2.0 - similar to SPARC, IA-64 specs)
etc would probably lessen the confusion.
I might be the only one that sometimes mixes these kinds of things, but I'm not
sure I'm unique in that respect. ;-)
