The BDTImark2000

is a summary measure of DSP speed, distilled from a suite of DSP benchmarks (not shown) developed and independently verified

by Berkeley Design Technology, Inc. A higher BDTImark2000

score indicates a faster processor. For a complete description of the BDTImark2000

and

underlying benchmarking methodology, as well as additional scores, please visit http://www.bdti.com. BDTImark2000
