C++: 64 bit performance vs. 32 bit All, Does anyone know how much performance speedup I can expect by using 64 bit C++ / Windows XP 64 bit over the 32 bit versions? Did anyone test this under Visual Studio 2005 or Intel C++ 8.1/9.0 ? My application domain is montecarlo simulations but any test would be great. Regards Lars Schouw ... 14 Mar 2006 13:24
The Fastest CPU Until a few days ago, the fastest CPU's were the RCA 1802's onboard the Pioneer and Voyager spacecraft. However the New Horizons spacecraft is supposed to reach an even greater velocity relative to Earth. Does anyone know what CPU's are onboard this vehicle, and when (before or after Jupiter assist) it will reach... 24 Feb 2006 14:22
AMD's new memory I haven't seen any discussion of this news yet: http://www.eetimes.com/news/semi/showArticle.jhtml;jsessionid=V2AQAAYC3GVIQQSNDBESKHA?articleID=177101749 This article says that AMD has licensed a new technology from Innovative Silicon which supposedly shrinks the size of embedded RAM (read: cache) by a factor of ... 27 Jan 2006 19:16
Would multi-core replace SMPs? Or have multi-core processors already replaced Symmetric Multiprocesors? Are there scenarios that multicores are better than SMPs and vice versa? Did manufacturers abadon SMPs in favor of multicores? Is there a future for SMPs? ... 10 Feb 2006 11:35
MIPS based Systems Hello guys! I am researching about MIPS based systems video card and cotrollers usage and specifications and i am having a hard time in it.. so i would appreciate if somebody can give a hand plz.. thnx guys ... 16 Jan 2006 13:43
CPU clock speed progress Now and then I look at how CPU speed progresses with the process generations. Since I tend to look at the fastest speeds for a given process, and supposedly the 90nm generation is going to be replaced by the 90nm generation soon, this may be a good time for the update. However, we have seen faster 130nm chips long... 10 Jan 2006 04:24
Average Seek times are pretty confusing I am trying to find the average seek time of the following single-platter disk. I know that the seek time is 1ms for every 100 tracks traversed. The total number of tracks on one side of the platter is 30,000. Then what is the average seek time? I think it is: 1ms/100 .... it makes sense, right? ... 15 Jan 2006 09:39
I/O Controller On a typical microprocessor, a distinct I/O address is used to refer to the I/O data registers and a distinct address for the control and status registers in an I/O controller for a given device. Such registers are refered to as ports. In intel 8088, two I/O instruction formats are used. In one format, the 8-bit op... 30 Dec 2005 12:02
interrupt-driven I/O Consider a system employing interrupt-driven I/O for a particular device that transers data at an avergae of 8KB/s on a continuous basis: a) Assume that interrupt processing take around 100 microsecond (i.e. time to jump to the interrupt service routine (ISR), execute it, and return to the main program). Determi... 31 Dec 2005 09:18
simplescalar simulation Hi, I work with sim-outorder, I try to find the number of register for each instruction carried out, in commit stage of simplescalar. my question, my simulation is with Spec2000 which is not free, can you help me on this subject. Thank you Friend for Simplescalar Mourad BOUACHE Boumerdes's University... 11 Dec 2005 17:20 |
