#1410 — Patent application

Let me mention in passing the following patent application which is 
publicly visible:

http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PG01&s1=glew.IN.&OS=IN/glew&RS=IN/glew

20110078389

MANAGING AND IMPLEMENTING METADATA IN CENTRAL PROCESSING UNIT USING 
REGISTER EXTENSIONS

A set of default registers of a processor are expanded into metadata 
registers on the processor of a computer system. The default registers 
having stored thereon data, while metadata which is related to the data 
is stored separately on the metadata registers.

It will be interesting to see what IBM has to say about this w.r.t.
their RISC architecture tagging scheme.

Seems like swatting a mosquito with a sledgehammer?

If you're going to put metadata into memory, why limit the advantage
to bounds checking?

It's easy, conceptually at least, to imagine accomplishing many of the
goals of object-oriented programming in hardware, so that the computer
would "know" when a given calculation makes no sense.  You could have
a multitude of data types, the rules for which you inform the
hardware, so that, for a trivial example, your calculations would be
at least dimensionally correct.

c programmers would still do ugly casts to get around the hardware
checking, but nothing short of genocide would fix c programming.

Robert.

Amusing:  my present employer shoots mosquitoes with a laser.

(0) The patent application makes no claims about memory metadata, 
although it does mention it in passing.

(1) I don't want to stop at bounds checking.

(2) However, I am not at all certain that classic data types are a good 
use of such metadata.  Now, the memory mechanisms referred to in the 
patent, but not claimed, allow large amounts of memory metadata to used; 
but, still, there are limits.

(3) As an OS guy, I tend to think more about providing mandatory 
security, not just security that can be turned off via a cast. Although 
I think it is key that there must be a layer of optional security, that 
can be cast around.  I discussed this in comp.arch years ago, before the 
work reflected in this patent application.


Anyway, the answer to any question along the line of "Why stop there?", 
not just for the sort of thing mentioned in the patent but for other 
things, is usually "We thought of going further, we may even have wanted 
to go further, or have plans to go further, but we stopped where we did 
because it was enough for a first step."  Or "because this is as much as 
we thought we might be able to push through".  Or "more than enough".

Dave Sager said something like:  it's not hard to figure out what the 
ultimate, ideal, form of XYZZY computer architecture should be.  It is 
hard to figure out the small incremental steps that can get there.
