I'm the technical marketing manager for the Series 32000 product line. The product line consists of the various components, software and system level products. In other words, if its Series 32000 I'm involved in some way.. In the last 24 hours, two articles were posted on the net that drove me to learning the tricks of posting my own article. If I've made an error in the process, please excuse. Yes, National has previewed the NS32532, and we have done that prior to having functional silicon. We recognize that this is a departure from past practices at NSC. We didn't do this as a result of any prior announcements by Mot or AMD. We did it because we believe that the NS32532 is really a revolutionary device of sufficient importance to deserve special consideration. We have discussed the design of the NS32532 with several companies over the past year BUT all of this was under non-disclosure. We did this as a fine tuning process to ensure that the part was correctly architected. We believe we have achieved our architectural objective. The design is frozen. Now to ease our discussions with a broader customer base, we have gone public. Yes, it is true that all we have today are simulated results. But we have more than just a simulation model. We are in the final stages of a 5 year effort in designing this new addition to the Series 32000 family. We are running extensive test vectors to ensure the integrity of the design prior to generating our first mask set. We are very confident that we will have customer samples in the fourth calendar quarter of 1987. What is so impressive about this project is that we are STILL ON OUR ORIGINAL SCHEDULE. I wish I had more than just simulated results, in a few short months, we will. For my friend Landon at Amdahl, I would like to say that the simulated dhrystones results we published are real. Since he asked several pointed questions, I'll provide results du jour if you wish. Let me give you some details ------ 32332 @ 15 MHZ version 1.0 optimized ............ 3943.5 32332 @ 15 MHZ version 1.1 optimized ............ 3183.0 32332 @ 15 MHZ version 1.1 no global opt......... 2724.0 32532 @ 30 MHZ version 1.0 optimized ............ 19800 32532 @ 30 MHZ version 1.1 optimized ............ 16600 32532 @ 30 MHZ version 1.1 no global opt ........ 14100 Yes we have a new set of compilers in the works that among other things supports global optimizations. I don't care which compilers you use on which version of the benchmark, the 532 is better than 5X improvement over todays 332 and over 11.7X faster than the 32032. OK you say ---- the 532 has a faster clock ------ lets factor that out of the equation. the 32532 is 2.53X the 32332 at the same frequency the 32532 is 3.86 the 32032 at the same frequency Yes we have made significant architectural changes(hardware only) that provides this significant increase. It's not imaginary and Landon, it isn't marketing hype. It's fact. The numbers quoted were measured by the designers( members of the compiler team included) and NOT created by any of us in Marketing. An offer I have for you Landon ------ COME ON DOWN I'll give you a load of documentation and we can arrange a time to show you the simulator in action. One caveate: I only have the low end simulator running on my system and I don't have the latest tools so I can't show you the listed results but I can get close. I CAN show you the improvement delta.
