A Novel Recursive Algorithm for Bit-Efficient Realization of Arbitrary Length Inverse Modified Cosine Transforms

Koenig, R.; Stripf, T.; Becker, J.

Abstract:
In this paper a novel approach for inverse modified cosine transform (IMDCT) computation is presented, based on a recursive algorithm. Due to its nature, this IMDCT calculation can be performed on a reduced bit width datapath without loss of accuracy, compared to alternative recursive architectures. Combined with the regular structure, the approach allows for a much more area efficient VLSI implementation compared to existing systems. Due to its bit efficiency this approach is attractive to be implemented on reconfigurable architectures of the DSP domain as well.
