Signal specialist releases DSP performance benchmarks
Steve Bush US signal processing specialist Berkeley Design Technology (BDT) has released a DSP performance benchmark. Called BDTImark, the company claims it provides a realistic way of comparing processing performance of DSPs with differing architectures and clock speeds. Eleven selected DSP algorithm kernels, including FFTs and FIR filters, are used to gauge performance. These algorithm kernels have been chosen because they are the core DSP tasks and can be handwritten by BDT with reasonable ease. The alternative, says BDT, is to tailor code for a specific task but this would take an unrealistic amount of effort for a benchmarking company. Using C to generate code more quickly would result in a benchmark that includes compiler performance. BDTImark is a composite score that takes into account the execution time of all 11 benchmarks.
