Title: PC Specifications for SDR-1000

My apologies for missing your earlier message.  Obviously the faster the CPU, the better for real time audio applications.  I am currently developing on a Celeron 2.4GHz with 512MB of ram and integrated video.  My home machine is built more for PC gaming, and therefore has a bit more graphics horsepower (ATI 9800, 1GB ram).  Clearly both of these are way above the minimum 800MHz machine as specified on our specs webpage.  I would recommend a P4 w/800MHz FSB if you plan to do high speed CW.  The faster “real-time” timer on the motherboard can improve the timing on speeds surpassing 35 WPM.   There has been no testing that I am aware of on 64 bit operating systems to date.  For this reason, I can’t do much more than make a general statement that I believe a 64-bit version of the PowerSDR is possible and will come to fruition with or without FlexRadio’s help thanks to the GPL nature of our software.   Eric Wachsmann FlexRadio Systems   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tim Ellison Sent: Monday, August 29, 2005 11:32 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] PC Specifications for SDR-1000   To all, I am starting to put together a PC system for use with a SDR-1000 and PowerSDR I am planning to get in the near future and had a couple of questions. What performance metric is most desirable in a CPU / motherboard combination?  I want to make sure I get a system that will meet current and future performance needs.  I have not done a lot of research on the DLLs or libraries used, so I was hoping to get some insight from those that know a lot more about the internal operation of PowerSDR than I. Specifically, what is most to least important of the following items (a ranking of sort): Floating point performance Integer operation Memory performance Multi-tasking performance CPU cache Graphics performance   In addition to processor / motherboard metrics, has anyone used Windows XP Professional x64 with PowerSDR.  If so how did the WOW64 emulation handle PowerSDR and is there any advantage to using a 64-bit OS.  Will PowerSDR be compiled to be a 64-bit app in the future? Also, are there any known compatibility issues with AMD processors? In advance, thanks for the information. 73 de W4TME   -Tim --- Tim Ellison Integrated Technical Services Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell >>> PGP public key available at all public KeyServers <<<
