      <description><![CDATA[ Hello Byeongheon,
I was out of the office for the past two weeks, so I only saw your message today. Were you able to download the library?
Thanks,
Marius Cornea

      <description><![CDATA[ Sorry I know these may be questions that can't be "officially" answered, but I'm curious and would be happy if you could give hints at unofficial answers :-)

Does Intel plan to fully support the IEEE 754-2008 in future hardware?

Any idea as to when this might happen?

Thanks ]]></description>

      <description><![CDATA[ Hi,
Actually, in my personal opinion there will not be a complete hardware implementation of the IEEE Standard 754-2008 any time soon (i.e. for many years to come). The reason is that there are many features in the standard - take correctly rounded transcendentals for example - that are extremely costly to implement in hardware, while very good software solutions exist, or can be found. There is no good justification to have a hardware-only implementation.

      <description><![CDATA[ Weren't similar things said in 85.  I mean if anyone (like a scientist or engineer) need that kind of fp performance they could buy a 8087  ;-)

I would think that decimal and long double (128 bit) would benefit considerably from direct hardware support.  Still it would not surprise me if a full hardware implementation would take a couple of years (assuming the changes have been anticipated and are already 'in the pipe'). ]]></description>

      <description><![CDATA[ The Intel® 8087 implemented everything that was important in the old IEEE standard 754 (even before it became a standard), but left certain operations to software. This will most likely be the case with the new standard too and any future hardware implementations of it (or rather of a subset; as the standard states, it is acceptable to implement it in a combination of HW and SW - no one can realistically expect a hardware-only implementation) ]]></description>

      <description><![CDATA[ There are 3 CPU designs that presently implement IEEE 754-2008. The first was the IBM System z9, in microcode. That was a prudent design approach since the z9 started shipping in 2005 (with the DFP-capable microcode somewhat later), well before the standard was officially finalized. A microcode (or what IBM more correctly calls millicode) implementation allowed any post-shipment correction if the draft standard shifted while still providing an orders-of-magnitude performance boost versus a software implementation.

IBM's POWER6 (2007) and System z10 (2008) processors both implement IEEE 754-2008 fully in hardware and in every core. By the time they shipped there was much less uncertainty about the final standard.

If you're a "CPU geek," there's a technical paper describing the z10 hardware implementation here:

http://www.research.ibm.com/journal/rd/531/schwarz.pdf

The z10 DFP implementation is very similar to POWER6. There are 54 DFP instructions implemented in hardware, and they are common to the POWER6 and z10 CPUs (and z9, for that matter). The z10 decimal floating point unit adds support for 13 decimal fixed-point instructions, but these are simply preexisting instructions traditionally important to the z CPU family that were relocated and reimplemented for z10, to improve their performance. ]]></description>
