Addressing the performance gap at every price point
With the addition of the new Spartan-DSP series, the XtremeDSP Portfolio delivers 20 GMACS for
under $30. The Portfolio fills the performance gap created by the growth in algorithmic complexity
and limitations of traditional sequential processors in signal processing applications.
* Algorithm Complexity: As demand for processing power is rapidly increasing, sequential processing cannot support
the algorithmic complexities within the required response times; to overcome these architectural limitations,
parallel processing offered by XtremeDSP devices is essential
The industry-proven highest performance DSP
• Over 350 billion multiply-accumulate operations per second (GMACS)
• Parallelism with distributed memory enables sample rate to equal the clock rate—up to
• High internal memory bandwidth—1.5 to 19.3 Gbps (not including distributed memory)
• Abundant on-chip memory—1.8 to 10.3 Mbits
