Introduction The Spartan®-3A DSP family of Field-Programmable Gate Arrays (FPGAs) solves the design challenges in most high-volume, cost-sensitive, high-performance DSP applications. The two-member family offers densities ranging from 1.8 to 3.4 million system gates, as shown in Table 1. The Spartan-3A DSP family builds on the success of the Spartan-3A FPGA family by increasing the amount of memory per logic and adding XtremeDSP™ DSP48A slices. New features improve system performance and reduce the cost of configuration. These Spartan-3A DSP FPGA enhancements, combined with proven 90 nm process technology, deliver more functionality and bandwidth per dollar than ever before, setting the new standard in the programmable logic and DSP processing industry.
