Altera Competitive Analysis • Cores • Good Multipliers and Parallel FIR • Inefficient SDA FIR filters • Most Altera reference designs are parameterizable • Easy to do with AHDL code • Not Smart-IP • More 3rd party DSP IP - but not effective • Little internal DSP IP • Customer 3rd party IP evaluation capability (security) • No announced DSP system level tools
SDA FIR Filter • Most commonly used core • Parallel In, Parallel Out • Bit serial processing • All taps processed in parallel • Full precession through entire core • One clock cycle required for each data bit • One additional clock cycle for symmetric filters
The Solution to High Performance DSP • Higher performance • 10X faster, parallel processing • Lower power • 50% to 80% less than DSP processors • Lower price • 1/5th the cost, Spartan FPGAs at ASIC prices • Faster time to market • Simpler design flow, no real-time software Add a Xilinx FPGA, not more processors
