A class to detect ALL the features of the CPU / CPUs in the local system. Now at version 1.2
<!------------------------------- STEP 2 ---------------------------><!-- Include download and sample image information. -->

Camel is a generic Windows® / Linux CPU detection class which can display details about the hardware installed within the computer. It can display items such as the CPU manufacturer, CPU model and name, clock speed and other hardware details.

What Do I Get With This?

Well a complete CPU identification and capabilities class. Also there is a complete Windows version detection algorithm included in the demo source. The demo (including pre-compiled binary) provides a replacement for WCPUID and similar applications and as the binary is < 150 kb, it is nice and small.

How Can I Use It?

1. E-Mail me for permission to use/include (always given). I just want to know what purpose it is being used for. It is provided completely for "Non-Commercial Usage."
2. Include the files in your C++ project.
3. Compile!
4. Play!

What About.... AKA: Specific In-depth Details

Supports Microsoft® Windows™ From:

Windows™ 95 / 95 OSR2 / 95 OSR2.5
Windows™ 98 / 98 SE
Windows™ Millennium
Windows™ NT 3.51
Windows™ NT 4.0 Workstation / Server [Including SP1 to SP6a]
Windows™ 2000 Workstation / Server / Advanced Server / Datacenter Server (Including SP1 to SP3)
Windows™ XP Personal / Professional [Including SP1]
Windows™ .NET Web Server / Standard Server / Enterprise Server

Supports Processors From:

Intel / AMD / Cyrix / Rise / UMC / IDT / Transmeta / NexGen / National Semiconductor

See Camel.txt for processor listings... E.g. Pentium III "Coppermine" or Athlon XP 1800+ (Thoroughbred Core).

Streaming SIMD Extensions [MMX]
Streaming SIMD Extensions 2

General Instruction Sets

Floating Point Unit [FPU]
Time Stamp Counter [TSC]
Conditional Move [CMOV]
Memory Type Range Registers [MTRR]

Other notes:

The 2nd generation CPU speed test is "loosely" based on code from Pavlos Touboulidis. It is far enough removed to be no-longer copyright to him. I think. Anyway this is the obligatory mention.

Known Bugs And Problems:

CAM_00000001: Last Tree Node Fails To Display '+' Icon Properly.
CAM_00000002: CPU Speed Detection Results With +/- 10MHz Deviation. (FIXED: Version 1.2)
CAM_00000003: Fails To Detect APIC ID Properly With < Intel P4 Processors.


Some of the functionality is missing. Some of the menu items do not yet work nor some of the benchmarks. None of these missing features affect the CPU identification code! I apologize and will implement these in time. Or you can.....
