FEBRUARY 11--The ADSP-TS101S TigerSHARCdigital signal processor (DSP) from Analog Devices Inc. (Norwood, MA; www.analog.com) is now shipping to customers. The device, which is implemented in a 0.13-μm process with eight layers of copper interconnect, is targeted at numerous signal-processing applications that rely on multiple processors working together to execute computationally intensive functions. TigerSHARC DSPs will be used in applications such as defense, medical, communications, video, and industrial systems, including the burgeoning 3G cellular base station market.
At a 250-MHz clock rate, the ADSP-TS101S offers a DSP industry-best 1500-MFLOPS peak performance and a floating-point, 1024-point complex FFT time of 39 μs. Moreover, ADI's high-performance TigerSHARC DSP has native support for multiple data types and processes 2 billion 16-bit multiply and accumulates per second (MACS) at 250 MHz. At these performance levels, TigerSHARC has a typical power dissipation of 1.5 W, making it optimal for multiprocessing applications where heat dissipation is a concern. The performance-enhanced TigerSHARC DSP offers a complete set of on-chip features including a 6-Mbit internal memory, 14-channel zero-overhead DMA engine, 1.8-Gbyte I/O throughput, and two types of integrated multiprocessing support.
Cluster multiprocessing allows for eight TigerSHARC DSPs, a host, and a global memory to connect without any addition logic. The link ports provide for a high-bandwidth point-to-point multiprocessing connection that is complementary to the cluster multiprocessing.
