Analog Devices has received leading benchmark results from independent signal-processing technology analysis firm, Berkeley Design Technology (BDTI) for its ADSP-TS201 TigerSHARC processor. BDTI's analysis found that the 600MHz TigerSHARC processor registered the highest floating-point BDTImark2000 score of any processor architecture tested by BDTI to date. The BDTImark2000 is one of the industry's most respected measures for digital signal processor (DSP) performance and is a frequent resource for system designers evaluating processors.
The BDTImark2000 provides a summary measure of DSP speed.
Specifically, the 600MHz TS201's BDTImark2000 score of 4430 significantly exceeded the BDTImark2000 scores of 3130 for the 1.4GHz Intel Pentium III, 750 for the 240MHz SH775x processor from Renesas, and 1100 for the 225MHz TMS320C67x processor from Texas Instruments.
"The ADSP-TS201's floating-point design delivers application developers greater computational precision and accuracy, while its high-speed, industry-leading on-chip memory density and excellent multiprocessor support make it a natural choice for applications ranging from wireless base stations, radar and sonar systems, and high-precision medical imaging to instrumentation and professional audio", according to Gerald A McGuire, General Manager, Media Platforms and Services Group, Analog Devices.
"Once again, TigerSHARC has distinguished itself as a best-in-class processor by coupling the world's highest floating point processor with the world's highest amount of on-chip memory and I/O", McGuire said.
"For deeply embedded signal processing applications, this allows designers to focus on applications, not on removing system level bottlenecks typically encountered in high-cost FPGA-based designs and expensive-to-develop ASIC-based designs.
Additionally, the unique ability of the TigerSHARC to process 1, 8, 16 and 32bit fixed-point data gives customers unparalleled flexibility in native data type support".
The ADSP-TS201 has earned a reputation as having the best performance density measured in terms of cost, power consumption and efficient use of board space.
Offering 3.6GFLOPS at 2.2W, the 600MHz TigerSHARC has the industry's best floating-point performance-per-watt ratio.
In a typical multiprocessor wireless basestation implementation, that translates to cooler operating temperatures, which enables systems developers to design in more processors per board to meet their performance needs.
