I have a whole load of unfinished hobby projects. Many times I was taken by some idea, implemented the most challenging part and lost my interest.
But some of the projects have been actually finished and may be interesting to someone.
<\/p>\n\n\n\n

It’s time to let the world see my creations \ud83d\ude42<\/p>\n\n\n\n

The hero of the day is the small cross-platform utility that measures the clock speed of the CPU and shows it alongside its summary information, such as brand name, family, stepping, etc.<\/p>\n\n\n\n

It started as a command-line application made in Borland C++ Builder. This IDE provides a straightforward and convenient syntax for embedding the x86 Assembler instructions into your regular C++ code. Which is great, when your application built around one of them: rdtsc<\/em><\/a>.<\/p>\n\n\n\n

\"\"<\/a>
freq.exe (download archive<\/a>)<\/figcaption><\/figure><\/div>\n\n\n\n

Here’s the code (please take into account, that I was not professional or even amateur programmer back then, so give me some slack):
<\/p>\n\n\n\n\n\n\n\n

<\/path><\/svg><\/div>
#include <stdio.h>\n#include <conio.h>\n#include <windows.h>\n\n__int64 Get_freq() {\n\n\tDWORD ts_hi, ts_lo;\n\tLARGE_INTEGER qpf, count_1, count_2;\n\tULARGE_INTEGER ts_before, ts_after;\n\n\tQueryPerformanceFrequency(&qpf);\n\n\t__int64 count_persec = qpf.QuadPart;\n\n\n\tasm {\n        rdtsc\n        push eax\n        push edx\n\t}\n\n\tQueryPerformanceCounter(&count_1);\n\n\twhile (count_2.QuadPart - count_1.QuadPart < count_persec) {\n\n\t\tQueryPerformanceCounter(&count_2);\n\n\t}\n\n\tasm {\n        rdtsc\n        push eax\n        push edx\n\t}\n\n\tasm {\n        pop ts_hi\n        pop ts_lo\n\t}\n\n\tts_after.HighPart = ts_hi;\n\tts_after.LowPart = ts_lo;\n\n\tasm {\n        pop ts_hi\n        pop ts_lo\n\t}\n\n\tts_before.HighPart = ts_hi;\n\tts_before.LowPart = ts_lo;\n\n\treturn ts_after.QuadPart - ts_before.QuadPart;\n\n};\n\nvoid  main()\n{\n    char ch;\n\n    printf(\"Press \\\"q\\\" for exit or any other for detecting CPU clock frequency again\\n\\n\" );\n\n    ch = getch();\n\n    while (ch != 'q'){\n\n        printf(\"Frequency = %u Hz\\n\", Get_freq());\n        ch = getch();\n\n    }\n}<\/pre><\/div>\n\n\n\n
There was not so much information on this topic available except the MSDN library and Intel’s Instruction Set Reference. But Borland’s documentation was good enough too, as far as I remember.<\/p>\n\n\n\n
 In a few months, I ported this to the MS Visual C++. As you can see, the ASM instructions were replaced with the MSVC’s intrinsic functions.  The clock frequency alone is not so exciting, so I added some basic processor information, that is returned by the cpuid <\/em>instruction<\/a>:<\/p>\n\n\n\n

 But this was just a preparation for the next step.<\/p>\n\n\n\n

Why is it called “OverSoft CPU Informer XP”? Well, that’s a story for another day \ud83d\ude42<\/p>\n\n\n\n
A few years later, in 2011, when I was a full-time web developer already and used FreeBSD as a desktop system at work, I ported the CLI version to the GCC just for fun. My colleague, who’s an actual C++ developer helped me with that. Thanks to a MinGW project, the utility may run on Windows (as well as on macOS) too:<\/p>\n\n\n\n
\"\"<\/a><\/figure><\/div>\n\n\n\n
And now, I’m sharing the cross-platform code on GitHub<\/a> under a permissive license. To make it somewhat usable, I added the Makefile and README files. The rest is a genuine 9-years-old cpp code, which is still compilable by some miracle. The binary executable files for 32 and 64 bit Windows and 64 bit Linux are also available there.
