The BDTI DSP Kernel Benchmarks™The BDTI DSP Kernel Benchmarks (formerly known as The BDTI Benchmarks) are the most widely used digital signal processing benchmarks in the world. Nearly every major vendor or buyer of processors for DSP uses this benchmark suite. Why? Because it is the only vendor-independent suite of digital signal processing benchmarks, and each benchmark is carefully designed by BDTI’s team of DSP and benchmarking experts. These benchmarks are recognized industry-wide as trustworthy, reliable, and accurate. And because they are so widely used, BDTI provides a vast pool of benchmark data—giving you the context you need to evaluate a processor’s results. The BDTI DSP Kernel Benchmarks are essential for both processor vendors and processor users; each derives unique benefits from using BDTI’s benchmarks.
Advantages For Processor VendorsYou need to convince your customers that your processor has the performance they’re looking for, so you’ll need to provide them with benchmark results. But customers are invariably skeptical of benchmark results from companies that are trying to sell them something. They have no way of knowing whether the results are real and accurate, and whether they are comparable to results from other vendors. If you use the BDTI DSP Kernel Benchmarks these problems disappear. Processor users recognize the integrity of BDTI’s benchmarks, and they are far more likely to believe your marketing pitch if you have independently certified results to back it up. BDTI’s benchmarks evaluate all of the key performance metrics, including speed, energy efficiency, cost-performance, and memory use. And because BDTI has benchmarked dozens of processors with this suite, you’ll be able to present apples-to-apples performance comparisons to your competitors—and seal the deal. Of course, BDTI’s benchmarks are useful for more than marketing; many vendors have used the BDTI DSP Kernel Benchmarks to evaluate and improve processor designs that are still in progress. The BDTI DSP Kernel Benchmarks are also used to generate BDTI’s composite metrics, which include:

Advantages For Processor UsersChoosing the best processor for your product is one of the most important design decisions you’ll make. If you get it wrong, your product may not work as well as you’d hoped—or it may not work at all. To make a good decision, you’ll need benchmark results. But not just any results will do—you need to know that the results you’re using are trustworthy, unbiased, and accurate. Most processor vendors provide results for their own processors, but there is no way to know whether those results are comparable to results from other vendors. Some vendors are more careful and fair than others, but few have the resources to create high-quality and technically sound benchmarks, and then implement them across a range of competitor processors. BDTI has over a decade of experience in developing and implementing signal processing benchmarks, and we are recognized worldwide as the independent benchmarking experts. If you use our benchmark results you’ll be confident that you’re basing your decisions on unbiased performance data. Better yet, you can compare results for many different processors—from many different vendors—easily, quickly, and reliably. Visit our benchmark results web pages to view and compare our composite metrics (e.g., the BDTImark2000™ and the BDTImemMark2000™) results for a variety of processors and cores. These metrics are based on processors’ performance on the BDTI DSP Kernel Benchmarks. If you don’t see results for the chips you need, contact the chip vendor to let them know that you’d like to see BDTI benchmark results for their chips.
About the BDTI DSP Kernel BenchmarksThe BDTI DSP Kernel Benchmarks™ are a suite of twelve DSP algorithm kernel benchmarks that represent the key building-block operations found in most signal processing applications. These benchmarks are relatively simple, and are quick to simulate. The BDTI DSP Kernel Benchmarks measure only the performance of the processor core; they do not evaluate the effects of I/O, peripherals, or external memory. Therefore they are appropriate for both processor chips and licensable processor cores, and can be used to assess performance even when the I/O, peripherals, or external memory have not yet been defined.
Options for Using the BDTI DSP Kernel BenchmarksThe BDTI DSP Kernel Benchmarks have been used by dozens of processor vendors and OEMs to evaluate and compare processor performance, to identify architectural strengths and weaknesses, and to enable credible product marketing. (See “Value of BDTI Benchmark Results and Analysis”.) There are several different plans for engaging with BDTI to use the BDTI DSP Kernel Benchmarks, obtain a BDTImark2000™ score, and benefit from BDTI’s analysis of your processor. Plan A: License to the BDTI DSP Kernel Benchmarks™ SpecificationA license to the BDTI DSP Kernel Benchmarks includes:
Plan A does not include review and certification of benchmark results by BDTI, and therefore also does not include a BDTImark2000™ score. To maintain the credibility and objectivity of BDTI Benchmark results, BDTI requires certification of benchmark implementations before any benchmark data can be disclosed. Therefore, Plan A is most appropriate if you intend to use the benchmark results only for internal purposes. Plan B: License, Specification, and Certification of ResultsIn order to disclose BDTI Benchmark results, a vendor must obtain BDTI review and certification of benchmark implementations. Plan B provides:
Under Plan B, BDTI reviews benchmark implementations to verify timing and ensure that they are compliant with the Specification, functionally correct, and optimal. For certification, BDTI requires either a cycle-accurate software simulator or processor hardware development tools. After BDTI has certified the benchmark results, you may release benchmark data in compliance with BDTI’s guidelines for disclosure of benchmark results. Optionally, a licensee may contract with BDTI for implementation of the benchmarks. BDTI’s knowledge of signal processing and experience with a wide variety of architectures result in highly optimized implementations. Plan C: License, Specification, Certification of Results, and AnalysisPlan C provides a vendor with a complete evaluation. It includes:
A BDTI analysis provides an evaluation of your the processor following a format similar to that found in Buyer’s Guide to DSP Processors and reports in the Inside series. In its quantitative analysis, BDTI uses the benchmark results to identify the competitive strengths and weaknesses of your processor. A quantitative analysis examines the benchmark results using multiple metrics, such as cycle count, execution time, cost-performance, energy consumption, and memory use. In its qualitative analysis, BDTI considers important design issues that may not be reflected in the benchmark results, such as peripherals and development tools. The results of the quantitative and qualitative analyses are compiled into a detailed report. To license the BDTI DSP Kernel Benchmarks, initiate an analysis engagement, or discuss your needs, please contact BDTI. BDTI DSP Kernel Benchmarks Engineering ToolkitThe BDTI DSP Kernel Benchmarks Engineering Toolkit™ combines the BDTI DSP Kernel Benchmarks, the industry’s most reliable benchmarks for signal processing applications, with a rich library of competitive information and a flexible tool for making comparisons and weighing design trade-offs.
