x86 - Unhandled exception in using intrinsic -

x86 - Unhandled exception in using intrinsic -

I have an application using VC ++, and in some tasks vectoring wanted to find optimization opprtunity.

To start with, I am trying to get the following code:

  __ m128i p1; P1.m128i_u32 [0] = 1; P1.m128i_u32 [1] = 2; P1.m128i_u32 [2] = 3; P1.m128i_u32 [3] = 4; __m128i p2; P2.m128i_u32 [0] = 1; P2.m128i_u32 [1] = 2; P2.m128i_u32 [2] = 3; P2.m128i_u32 [3] = 4; __m128i res2 = _mm_mul_epi32 (P1, P2); However, when I have executed _mm_mul_epi32, I am getting an unrestricted exception or invalid operation error; I have no indication why this happens, can someone please tell me? What is wrong?  PMULDQ    
 class = "text"> itemprop = "text">   _mm_mul_epi32  map, Available only in SSE4 and AVX. For the SSE4 or AVX, you definitely need an Intel CPU recently, e.g. NEHEMMEM, Sandy Bridge (Core i5, i7).  
 Note that you may find it easier and easier to use the interface to start the SIMD vectors, e.g.  
  __M 128i page 1 = _mm_set_epi32 (1, 2, 3, 4); __m128i p2 = _mm_set_epi32 (1, 2, 3, 4); __m128i res2 = _mm_mul_epi32 (P1, P2);

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
