Behavior of some convert instructions with W=1 in non-64-bit mode

For instructions such as VCVTSI2SD, your doc is clear.  It says that in non-64 bit mode, W=1 will be have the same as W=0.  That is, the second source will be 32 bits memory or a 32 bit GPR.

HOWEVER, AMD's doc says something different.  I very rarely have seen any difference between Intel and AMD docs, and this is one such occasion.  To me, it is very important for reasons of software compatibility to resolve any such differences.

In AMD Volume 4, page 101, it says:

SGX support removed from Intel's ARK website?

Hi Intel


Until recently (1-2 weeks ago), Intel's ARK website listed SGX as being supported on the new Skylake 6600K and 6700K processors. However, this information now seems to have been removed? The page I'm talking about is (for the 6700K):

So does this mean SGX is no longer supported on these processors?



Exposing processor features to dynamic languages

It always causes me exquisite pain to see someone laboriously copying down a long number from their computer screen, just to type it in to another window or application. Doesn't it for you?

After all, doesn't everyone know about the cut-copy-paste keys? I'm talking about selecting text with your cursor and using control-C for copy and control-V for paste.

A Mission-Critical Big Data Platform for the Real-Time Enterprise

As the volume and velocity of enterprise data continue to grow, extracting high-value insight is becoming more challenging and more important. Businesses that can analyze fresh operational data instantly—without the delays of traditional data warehouses and data marts—can make the right decisions faster to deliver better outcomes.

    This algorithm can be used to improve sparse matrix-vector and matrix-matrix multiplication in any numerical computation. As we know, there are lots of applications involving semi-sparse matrix computation in High Performance Computing. Additionally, in popular perceptual computing low-level engines, especially speech and facial recognition, semi-sparse matrices are found to be very common. Therefore, this invention can be applied to those mathematical libraries dedicated to these kinds of recognition engines.

    With the new SGX extensions available in the new Skylake based CPU's (6700K and 6600K) I was wondering if Intel is ready to release more information about these technologies. Specifically:


    1) Is there any plans for an emulator that can be used to emulate these technologies?
