Intel Recognition Primitive Library
Frequently Asked Questions

The Intel Recognition Primitive Library maintain the latest errata on the Intel Developer web site. Please check the library errata for further information.

Q: Would application developed using the Intel Recognition Primitive Library run on a system with non-Intel processors?

Q: What compiler environments do the Intel Recognition Primitive Library support?

Q: Where can I find the assembly code samples which implement MMX™ technology?

Q: What is the minimal installation for the use of Intel Recognition Primitive Library on a Pentium® processor?

Q: What is the minimal installation for application development with Intel Recognition Primitive Library?

Q: There are a lot of function overlap between the Intel Recognition Primitive Library and Signal Processing Library. Which library should I use to get the best performance for FFT and the others?

Q: Can I use the Intel Signal Processing Library and Intel Recognition Primitive Library together?

Q: We want to train our HMM based speech recognition models on Unix workstations and use them on a Pentium processor PC using Intel Recognition Primitive Library. We need to know if you have a tool to generate directly trained models?

Q: Your HMM functions do not have restitution algorithms such as Boum-Welsh re-estimation, do you intend to implant them one day?




Q: Would application developed using the Intel Recognition Primitive Library run on a system with non-Intel processors?
A: Our libraries will run on any processor that is 100% compatible with the Intel Architecture.
Intel is happy to compete with other companies - the price/performance/quality of our processors speaks for itself.

Q: What compiler environments do the Intel Recognition Primitive Library support?
A: Please refer to the library release notes or the library web site http://developer.intel.com/design/perftool/perflibst/rpl/sysreq.htm for more detail.

Q: Where can I find the assembly code samples which implement MMX™ technology?
A: Please visit the Intel’s WWW site, in particular http://developer.intel.com/drg/mmx/appnotes, for sample code for several common operations.

Q: What is the minimal installation for the use of Intel Recognition Primitive Library on a Pentium® processor?
A: The Intel Recognition Primitive Library release is for software developer. So any installation will target for all Intel Architecture processors. For end user distribution, you only need three files, namely NSP.DLL, NSPP5.DLL, and the CPUID32.DLL to run on a Pentium Processor system.

Q: What is the minimal installation for application development with Intel Recognition Primitive Library?
A: The RPLDLL.EXE is all you need if your application will use the Intel Recognition Primitive Library DLLs only.
If you want to create custom DLL, you can download the RPLLIBMS.EXE instead.
If you want to use static library only, for Microsoft development environment, install the RPLLIBMS.EXE. For Borland development environment, install the RPLLIBBC.EXE.

For redistribution to your customer, you might want to check the customer CPU type, and then just install only the specific DLL on the filename, directory name, or volume label syntax is incorrect. target system.

Q: There are a lot of function overlap between the Intel Recognition Primitive Library and Signal Processing Library. Which library should I use to get the best performance for FFT and the others?
A: We understand this situation, and is in the process of consolidate these two libraries. Currently, the performance for function of both library are almost identical, except the FFT function.

In the Intel Recognition Primitive Library, you will see a slight advantage for lower order FFT. But this code will be merged into the Intel Signal Processing Library later on.

Q: Can I use the Intel Signal Processing Library and Intel Recognition Primitive Library together?
A: Yes. There used to be some problem with the previous version of these libraries.

Q: We want to train our HMM based speech recognition models on Unix workstations and use them on a Pentium processor PC using Intel Recognition Primitive Library. We need to know if you have a tool to generate directly trained models?
A: No, we do not support any tool in this type of setup.

Q: Your HMM functions do not have restitution algorithms such as Boum-Welsh re-estimation, do you intend to implant them one day?
A: Yes. The Intel Recognition Primitive Library version 4.0 will support the training for the HMM model. Several re-estimation algorithms will be implemented. If you have request for a particular algorithm, we would like to hear from you. Our library development is customer driven, hence, we are opened for suggestions.
