有很多种方法来比较不同DSP解决方案的性能,但以下三种是目前最常用的:
There are many ways to compare the performance of different DSP solutions, and each provides a different level of accuracy. The following are three ways to compare DSP performance.
• Embedded Multipliers Performance: This is a simplistic method for comparing relative DSP performance that does not take into account the supporting architecture surrounding the embedded multipliers and the complexity and performance of the overall DSP design. This method is the least accurate of the three.
• DSP IP Benchmarks: This method is a more accurate performance comparison between different silicon solutions because it measures the performance of popular functional operations that are integral to many DSP designs. Finite Impulse Response (FIR) filtering and Fast Fourier Transforms (FFT) are two of the most common DSP IP benchmarks.
• Application Level Benchmarks: This method precisely measures the performance of a particular silicon solution when implementing a specific application. An example is the benchmarking results from Berkeley Design Technology Inc. (BDTI).
