An excellent method for evaluating DSP performance is to look at industry standard benchmarks. In lines this example, we're going to use the BDTI benchmark, which is an independent standard MSC7116VF1000, benchmark recognized by the DSP industry. The benchmark was developed and independently MSC7119VM1200

verified by Berkeley Design Technology, Incorporated. product 2010: The BDTIMark2000™ is a summary measure of a processors’ signal-processing speed distilled from a suite of signal-processing benchmarks. The higher the score, the faster the performance. So, let's take a look at the DSPs that we mentioned earlier and look at their BDTI scores. September BGA-packaged Let’s begin by reviewing Freescale's MSC711x series devices. MSC7119VF1200, to The MSC711x is available in two different speeds, 200 megahertz… prior …and 300 megahertz. But we'll focus in on the 300 megahertz devices. We see that the MSC711x BDTI indexed score is 3,370. States Commission, When we compare this score against the other devices, such as Analog Devices BF53x series BlackfinDSPs running at 600 megahertz,… MSC7118VM1200, Trade United …we see that the MSC711x, even at 300 megahertz, outperformed the Blackfin DSP. the

Now we will compare the MSC711x series device to the three TI devices. in sale

We see that the C55x, at 300 megahertz, the same frequency as the MSC711, scores significantly International lower at 1,460. or MSC7118VF1200,

We see that the C62x with 300 megahertz once again scores significantly lower at 1,920. States import

Now, in the TMS320C64 family, which is benchmarked at 600 megahertz, we see that the benchmark for

as a DSP, this is an important parameter that customers will want to consider. product 2010: The BDTI benchmark suite includes a specific test that measures control code memory usage in which a smaller score is better. This table illustrates that the MSC711x is able to accomplish that benchmark with 128 bytes of control code.
