FPGA Performance DSP FunctionsImplementing HighPerformance DSP Functions in Stratix & Stratix GX Devices November 2002, ver. 2.0 Application Note 215 Introduction Digital signal processing (DSP) is a rapidly advancing field. With products increasing in complexity, designers face the challenge of selecting a solution with both flexibility and high performance that can meet fast time-to-market requirements. DSP processors offer flexibility, but they lack real-time performance, while application-specific standard products (ASSPs) and application-specific integrated circuits (ASICs) offer performance, but they are inflexible. Only programmable logic devices (PLDs) offer both flexibility and high performance to meet advanced design challenges. The mathematical theory underlying basic DSP building blocks―such as the finite……
