Spartan-3A DSP FPGA
I/O Optimized Platform with Added DSP and BRAM Capabilities
The new Spartan®-3A DSP platform is ideal for cost sensitive DSP algorithmic and co-processing applications requiring significant DSP performance. The new Spartan-3A DSP platform consists of two devices, the XC3SD3400A and the XC3SD1800A. The XC3SD3400A delivers over 30 GMAC/s (30 billion multiply accumulate operations per second) and up to 2,200 Mbps memory bandwidth at a volume pricing.
