The silicon digital signal processing (DSP) architecture of the FPGA can make a big difference when implementing complex signal-processing algorithms. Altera’s Stratix V FPGAs, with the variable-precision DSP block architecture, are the only programmable devices that efficiently support many different precision levels, including floating-point implementations. Also, with a 64-bit cascade bus and accumulator, the designer does not have to sacrifice precision when the algorithm implementation requires multiple DSP blocks. This unique architecture provides increased system performance, reduced power consumption, and reduced architecture constraints for system algorithm designers.
