What is the interface that change the cpu frequency and the core voltage on the windows platform?

I want to find the interface supplied by windows to change the CPU frequency and core voltage. Thanks! ...

Getting WMI to read processor load faster.

Hi. I have a C# application, where I have to get the processor load. According to the accepted answer for this question, my options are to either use performance counters from either WMI or the System.Diagnostics namespace. I have a problem with the System.Diagnostics performance counter (as documented here), so my only option is to use...

Power efficient and Speed efficient architecture for Multimedia Applications

Hi, I am working on evaluating a embedded processor architecture which offers below features: a] 8 SIMD co-processing DSP kind of cores, b] Each core can do a 8 way SIMD c] Each core is a 8 execution slot VLIW as well. I want to use high video encoder(H.264, 1080p, 60fps) or 3D Video encoder to run on this processor/hardware. I am t...

Memory-mapped co-processor interface

Hi all, I have a very basic question. The architecture I am studying offers a memory-mapped co-processor Interface. Could somebody confirm that I understand this concept correctly: If I have a co-processor attached than some memory region on the bus system is reserved to communicate with the co-processor, ie to send and read data, execu...

Floating point versus fixed point: what are the pros/cons ?

Floating point type represents a number by storing its significant digits and its exponent separately on separate binary words so it fits in 16, 32, 64 or 128 bits. Fixed point type stores numbers with 2 words, one representing the integer part, another representing the part past the radix, in negative exponents, 2^-1, 2^-2, 2^-3, etc. ...

Hi Team, Very new in Android app. Installed Eclipse, SDK, configured AVD but not able to debug my "Hello World" app in Eclipse running on Windows Vista Home Premium SP2. When I am trying to debug - popup appears The JRE Instance default XSLT processor does not support debugging would you like to debug using the default Xalan 2.7.1 pr...

AS3 Time offsets "Clumping together" after window switching

Imagine you have 100 tweens. Each tween is simply an element (circle) that goes up, and then comes down again. By delaying each tween a bit from the previous, a sine wave effect is created. Now all this is working fine. The problem arises when you switch to another window or application, and then view the window with animation again. Th...

finding the server spec. on which my website runs

hi, i need to find out what are the details of the processor the server has. i need to know which kind of processor, type of OS, RAM etc. i've got a reply from one webhosting company: "This is a shared hosting server, it is a dual processor (quad core xeon 2.8) 16Gb ram, mirrored 300GB SAS15k drives" how can i get those details on othe...

How to be sure if a processor is 32bits or 64bits ? Are dual core processors 32 or 64 bits ?

Having a Macbook Pro with windows installed thanks to bootcamp, I have several questions: Under windows, I see that processes only use 50% maximum of the CPU charge, is that because the processor is a dual core and because the process is not multi-threaded ? Should I install windows xp version 64 bits instead, to have better performanc...

JVM load not shared between processor cores on linux

Hey, how come that JVM always uses only one from four cores ? If I run 2 or 3 Java apps, one core is employed on 100% and the rest is sleeping having nothing to do. Apps like Liferay, eclipse, sonatype nexus etc., multithreaded overlords. There is plenty of free RAM also. ps and top shows what I just said, and entire system gets out ...

How to set the trust level for processor ID in .net window application ?

I developing window application in C#. I created one installer with this windows application. It is running fine on nearly all computers. The window application takes the ID of processor & then based on that ID generates one unique key. On one computer it is giving the error "Windows installer failed to generate the key. Please contact y...

How to turn on Processor ID of the computer in bios ?

I am developing window application in C#. I have developed an installer which takes the processor ID of the computer & generates the unique key. My installer is running fine in almost all the computers but on one computer it is not able to read the processor ID. I debugged my program & I found that it has not the proper permissions to re...

How do cache lines work ?

I understand that the processor brings data into the cache via cache lines, which - for instance, on my atom processor - bring in about 64 bytes at a time, whatever the size of the actual data being read. My question is : Imagine that you need to read one byte from memory, which 64 bytes will be brought into the cache ? The two possib...

preconditions for a 64Bit virtual system

I just need to install Windows 2008 64Bit on a virtual machine. How to??? Do I need a special type of processor? Do I need a "special" virtualization tool? Actually installation fails on startup with the message that the CPU is not able to handle a 64Bit system. host system: Windows 7 64Bit CPU: Pentium D (seems to be Smithfield 805) ...

multiplication in multicycle datapath write from stratch

I wanted to know how the processor does multiplication in a multi-cycle data-path right from the beginning i.e from Instruction Reading -> decoding the instruction-> reading register files etc. In other word I wanted to know that given the booth's algorithm for multiplication implemented separately (a circuit is given) how will you ext...
