Folding (DSP implementation) (original) (raw)

Foldingis a transformation technique using in DSP architecture implementation for minimizing the number of functional blocks in synthesizing DSP architecture.Folding was first developed by and his students in 1992.Its concept is contrary to unfolding.Folding transforms an operation from a unit-time processing to N unit-times processing where N is called folding factor.Therefore, multiple same operations (less than N) used in original system could be replaced with a signal operation block in transformed system.Thus, in N unit-times, a functional block in transformed system could be reused to perform N operations in original system.
