Soft Multipliers For DSP Applications White Paper

New communication standards and high channel aggregation system requirements are pushing Digital Signal Processing (DSP) system performance requirements beyond the capabilities of digital signal processors. Altera’s new Stratix field-programmable gate array (FPGA) family includes embedded DSP block multipliers and large numbers of shallow memories with huge I/O bandwidth, making them an excellent solution for these high-end DSP systems. The largest silicon consumer of these DSP systems are the multipliers required by finite impulse response (FIR) filters and other DSP functions, so an efficient implementation of multipliers is the key for cost effective solution of these applications.
