DSPs provide high DSP performance at low cost points

Targeting to establish a new price-performance-power triad for DSP, Xilinx Inc. unveiled its low-cost Spartan-DSP series with development boards and enhanced design software.

Expanding the company's XtremeDSP products, Xilinx said the series provides high DSP performance at the lowest cost points in the industry, delivering over 20GMACs for under Rs.1,320 ($30), while consuming up to 50 per cent less dynamic power than other high-performance reconfigurable devices for DSP functions at this performance point.

The first platform in the Spartan-DSP series is the Spartan-3A DSP platform, optimised for wireless, low-cost video and consumer applications. The Spartan-3A features the 3SD3400A device delivering over 30GMACs and 2200Mbps memory bandwidth and the 3SD1800A device with over 20GMACs and 1500Mbps memory.

The Spartan-3A DSP architecture includes the new cost-optimised XtremeDSP slice (DSP48A) for independent arithmetic functions. The architecture also supports connecting multiple DSP48A slices to form wide math functions, DSP filters, and complex arithmetic functions without the use of general logic fabric, thereby reducing power consumption. The new DSP48A slice reduces power in common FIR filters by 50 per cent compared to other high-performance reconfigurable devices.

The new 9.1i releases of the Xilinx System Generator for DSP and AccelDSP synthesis software support industry approaches for designing Spartan3A-DSP devices as co-processing engines with DSPs or as stand-alone system platforms. System Generator for DSP is a high-level tool for the design, verification and debug of high-performance DSP systems.

Engineering samples are now shipping for the Spartan-3A DSP platform with the 3SD3400A device immediately available and the 3SD1800A device to follow next quarter. The 3SD3400A and 3SD1800A are priced at Rs.1,980 ($44.95) and Rs.1,320 ($29.85) in volume, respectively.
