Analog Devices TigerSHARC processor delivers high DSP performance

DECEMBER 16--Analog Devices Inc. (Norwood, MA; www.analog.com) has announced that its ADSP-TS101S TigerSHARC processor operates at 2.4 billion multiply accumulates per second (GMACS) and 1.8 billion floating-point operations per second (GFLOPS).

DECEMBER 16--Analog Devices Inc. (Norwood, MA; www.analog.com) has announced that its ADSP-TS101S TigerSHARC processor operates at 2.4 billion multiply accumulates per second (GMACS) and 1.8 billion floating-point operations per second (GFLOPS). This positions the TigerSHARC processor as offering the highest floating-point and fixed-point DSP performance available. Targeted at numerous signal-processing applications that rely on multiple processors working together to execute computationally intensive real-time functions, the TigerSHARC processor is well suited to video and communication markets, including the 3G cellular and broadband wireless base stations, as well as defense, medical imaging, and industrial instrumentation.

At a 300-MHz clock rate, the ADSP-TS101S offers 1.8 GFLOPS and 2.4 GMACS 16-bit fixed-point performance, as well as a 32-bit floating-point 1024 complex FFT time of 32.9 μs. The ADSP-TS101S offers a complete set of on-chip features such as a large 6-Mbit internal memory, 14-channel zero-overhead DMA engine, and 1.8-Gbyte I/O throughput.

TigerSHARC processor's two types of integrated multiprocessing support (link ports and a cluster bus) enable glueless scalability and unmatched I/O performance. The 32/64-bit cluster interface enables scaling of up to eight devices into a DSP system without the need for bridge chips or supporting logic. In turn, the link ports provide a high bandwidth point-to-point multiprocessing connection that is complementary to the cluster multiprocessing.
