• Radeon 68xx, 69xx cards and support for 10-bit color over displayport [closed]

  - by aCuria

  10-bit color, aka "Deep Color" is a scheme where 10 bits are used for each color channel. This makes for a 30 bit RGB implementation. IE: red: 10 bits green: 10 bits blue: 10 bits total: 30 bits For more information, please consult this link http://en.wikipedia.org/wiki/RGB_color_model#Beyond_truecolor:_deep_color Radeon 6000 series cards DO support deep color over HDMI, but HDMI also limits the output resolution to 1920x1200, which is not optimal. I want to know if Deep color is possible over display port with the HD6xxx series graphics cards.

• Data recovery on a data HDD (no OS)

  - by aCuria

  I am helping a family member with a dead hard disk. It is a seagate 200Gb 3.5" HDD in one of those old-school external enclosures. The problem was that windows failed to detect the hard disk when plugged in through USB. I removed the hard disk from its enclosure, and plugged it into my desktop PC. The BIOS does detect it upon POST, but unfortunately windows 7 would refuse to boot. It will get stuck on the loading screen with the glowing windows logo. Safe mode doesn't help either. What options do I have before going for some professional data recovery? edit: Someone modified the Title to something completely different from what I was asking, i just changed it back. 1) 2 HDD drives, DiskA(Dead), DiskB(my OS disk) 2) when B is connected to my system, everything works fine 3) when A AND B is connected, failure to boot. POSTs fine, but windows wont load 4) A has NO OS, its PURE data. It came from an EXTERNAL HDD enclosure which doesnt belong to me, and im trying to do data recovery.

• In-line assembly

  - by aCuria

  For the below code, if i want to convert the for loop to in-line assembly, how would it be done? (Pardon the weird code, i just made it up.) 1) This is for the x86, using visual studio 2) This is a "how to use in line assembly" question, not a "how to optimize this code" question 3) Any other example will be fine. I will think of some better example code in abit.

• using in-line asm to write a for loop with 2 comparisons

  - by aCuria

  I want to convert the for loop in the following code into assembly but i am not sure how to start. An explanation of how to do it and why it works would be appreciated. I am using VS2010, C++, writing for the x86. The code is as follows: for (n = 0; norm2 < 4.0 && n < N; ++n) { __asm{ ///a*a - b*b + x fld a // a fmul st(0), st(0) // aa fld b // b aa fmul st(0), st(0) // bb aa fsub // (aa-bb) // st(0) - st(1) fld x // x (aa-bb) fadd // (aa-bb+x) /// 2.0*a*b + y; fld d // d (aa-bb+x) fld a // d a (aa-bb+x) fmul // ad (aa-bb+x) fld b // b ad (aa-bb+x) fmul // abd (aa-bb+x) fld y // y adb (aa-bb+x) fadd // b:(adb+y) a:(aa-bb+x) fld st(0) //b b:(adb+y) a:(aa-bb+x) fmul st(0), st(0) // bb b:(adb+y) a:(aa-bb+x) fld st(2) // a bb b:(adb+y) a:(aa-bb+x) fmul st(0), st(0) // aa bb b:(adb+y) a:(aa-bb+x) fadd // aa+bb b:(adb+y) a:(aa-bb+x) fstp norm2 // store aa+bb to norm2, st(0) is popped. fstp b fstp a } }

• How does the compile choose which template function to call?

  - by aCuria

  Regarding the below code, how does the compiler choose which template function to call? If the const T& function is omitted, the T& function is always called. If the T& function is omitted, the const T& function is always called. If both are included, the results are as below. #include <iostream> #include <typeinfo> template <typename T> void function(const T &t) { std::cout << "function<" << typeid(T).name() << ">(const T&) called with t = " << t << std::endl; } template <typename T> void function(T &t) { std::cout << "function<" << typeid(T).name() << ">(T&) called with t = " << t << std::endl; } int main() { int i1 = 57; const int i2 = -6; int *pi1 = &i1; int *const pi3 = &i1; const int *pi2 = &i2; const int *const pi4 = &i2; function(pi1); ///just a normal pointer -> T& function(pi2); ///cannot change what we point to -> T& function(pi3); ///cannot change where we point -> const T& function(pi4); ///cannot change everything -> const T& return 0; } /* g++ output: function<Pi>(T&) called with t = 0x22cd24 function<PKi>(T&) called with t = 0x22cd20 function<Pi>(const T&) called with t = 0x22cd24 function<PKi>(const T&) called with t = 0x22cd20 */ /* bcc32 output: function<int *>(T&) called with t = 0012FF50 function<const int *>(T&) called with t = 0012FF4C function<int *>(const T&) called with t = 0012FF50 function<const int *>(const T&) called with t = 0012FF4C */ /* cl output: function<int *>(T&) called with t = 0012FF34 function<int const *>(T&) called with t = 0012FF28 function<int *>(const T&) called with t = 0012FF34 function<int const *>(const T&) called with t = 0012FF28 */

• File IO, Handling CRLF

  - by aCuria

  Hi, i am writing a program that takes a file and splits it up into multiple small files of a user specified size, then join the multiple small files back again. 1) the code must work for c, c++ 2) i am compiling with multiple compilers. I am reading and writing to the files by using the stl functions fread() and fwrite() The problem I am having pertains to CRLF. If the file I am reading from contains CRLF, then I want to retain it when i split and join the files back together. If the file contains LF, then i want to retain LF. Unfortunately, fread() seems to store CRLF as \n (I think), and whatever is written by fwrite() is compiler-dependent. How do i approach this problem? Thanks.
