On the Fastcode page, in the "rules" section this can be found: <quote> Pentium M Dothan Allowed instruction sets are: IA32, IA32 extensions, MMX, SSE, SSE2 and SSE3. </quote> (http://dennishomepage.gugs-cats.dk/Rules.htm) However i though my CPU was a Pentium Dothan, and i know it does *not* support SSE3. I downloaded Intel's Processor Identification utility, which can be found here: http://support.intel.com/support/processors/tools/piu/ When i run the utility it clearly reports SSE3 as missing: <report> Intel(R) Processor Identification Utility Version: 1.5.20050202 Time Stamp: 2005/03/20 13:08:55 Number of processors in system: 1 Current processor: #1 Processor Name: Intel(R) Pentium(R) M processor 725 1.60GHz Type: 0 Family: 6 Model: D Stepping: 6 Revision: 17 L1 Instruction Cache: 32 KB L1 Data Cache: 32 KB L2 Cache: 2 MB Packaging: µFCPGA/µFCBGA EIST: Yes MMX(TM): Yes SIMD: Yes SIMD2: Yes SIMD3: No Enhanced Halt State: No Execute Disable Bit: No Hyper-Threading Technology: No Intel(R) Extended Memory 64 Technology: No Expected Processor Frequency: 1.60 GHz Reported Processor Frequency: 1.60 GHz Expected System Bus Frequency: 400 MHz Reported System Bus Frequency: 400 MHz </report> Processor numbers are listed here: http://www.intel.com/products/processor_number/info.htm <quote> Intel® Pentium® M processor 725 90 nm 2MB L2 1.60 GHz 400 MHz </quote> Because the CPU has 2MB L2 cache and a 90 nm it seems it is indeed Dothan. Since it does not support SSE3 i guess SSE3 should be removed from the Dothan target as an allowable instruction set.

Since it does not support SSE3 i guess SSE3 should be removed from the Dothan target as an allowable instruction set. Some articles can also be found on the internet that seem to support Dothan not having SSE3. However there are also those that claim Dothan does support it. Some quotes with emphasis added: http://www.techreport.com/reviews/2005q1/dfi-855gme-mgf/index.x?pg=2 <quote> Like I said, those are just the highlights. In some ways, the Pentium M's design philosophy is the polar opposite of the Netburst architecture in the Pentium 4, which dedicates lots and lots of transistors to enabling higher clock speeds without much regard for power consumption. In others, the Pentium M is very much a modern Intel processor that shares features with the Netburst designs. Those features include SSE2 instructions, by the way, but *not SSE3*. </quote> http://www.clubic.com/article-16025-5-intel-pentium-m-745-dothan-.html <quote> Intel Pentium M 745 (Dothan) Processeur mobile LES PLUS Autonomie préservée Confortable quantité de cache L2 Petites améliorations de l'architecture LES MOINS *Pas de SSE3* ni d'HyperThreading FSB toujours à 400 MHz </quote> http://www.tweakers4u.de/cpu.php?h=2&sort=Fertigung&kat=&det= <quote> Wozu auch die ganze Architektur umkrempeln? Es genügt die vorhandene aufzupolieren, den Verbrauch zu senken und dabei die Leistung nochmals etwas zu erhöhen. Fraglich ist jedoch, warum Intel dem Dothan *nicht* wenigstens *SSE3* spendiert hat. Zwar gibt es nicht gerade viele Anwendungen die davon profitieren, doch wie man Intel kennt, wird die Firma diese Entwicklung nach vorne pushen. Von daher wäre dies durchaus wünschenswert, aber vielleicht sieht es selbst Intel noch nicht für erforderlich an, dies zu tun. </quote> The last site also shows a list with features for CPUs: http://www.tweakers4u.de/cpu.php?h=2&sort=Fertigung&kat=&det= Back to top Dennis Guest Posted: Sun Mar 20, 2005 5:17 pm    Post subject: Re: Dothan and SSE3 Hi Avatar I was so sure that SSE3 is supported by Dothan, but it looks like you are rigth. I will remove SSE3 from the Dothan target. Regards Dennis Back to top Dennis Guest Posted: Sun Mar 20, 2005 5:30 pm    Post subject: Re: Dothan and SSE3 Hi Avatar Fine. I believe know that Dothan does not support SSE3. Always go straight do the primary source when looking for reference info. Intel reference manuals etc. I trust the Intel ref tool too. How about the Fastcode CPU ID unit? Try executing some SSE3 code on your Dothan from the Trunc B&V.

A watch set to CPU yields this: (cvIntel, 1750, 6, 13, 32, 32, 2048, 0, [isFPU..isSSE2]) This FastCodeTarget variable has value fstPM.

I thought so too at first. However seeing articles contradict each other, and my CPU not executing SSE3 but still being Dothan ISTM Intel planned to add SSE3 at first, but ended up not doing so. The next Pentium M, Yonah, will have SSE3 though. Back to top Dennis Guest Posted: Sun Mar 20, 2005 6:08 pm    Post subject: Re: Dothan and SSE3 Hi Avatar Quote: I thought so too at first.

I had told my wife that I absolutely need a Dothan for the Fastcode project because it has SSE3 which Banias do not Now I have to make something up about the bigger L2 or something :-) Quote: The next Pentium M, Yonah, will have SSE3 though. When will that one be released? Dual core I suspect? Then I definately need such one ;-) Regards Dennis Back to top Avatar Zondertau Guest Posted: Sun Mar 20, 2005 6:29 pm    Post subject: Re: Dothan and SSE3 Quote: I thought so too at first.

I had told my wife that I absolutely need a Dothan for the Fastcode project because it has SSE3 which Banias do not Now I have to make something up about the bigger L2 or something I'm sure you'll come up with something: - Bigger cache - 90 nm instead of 130 nm - Lasts longer at top performance (but shorter at low performance) - Dothan is safer to be in than Banias Quote: The next Pentium M, Yonah, will have SSE3 though.

Then I definately need such one Yonah will be dual-core and will go into mass production in 2006 (or at least, that's what Intel plans): http://tinyurl.com/55n24 Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> Delphi Language BASM All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
