On VLSI design of rank-order filtering using DCRAM architecture
2008
Integration
This paper addresses on VLSI design of rank-order filtering (ROF) with a maskable memory for realtime speech and image processing applications. Based on a generic bit-sliced ROF algorithm, the proposed design uses a special-defined memory, called the dual-cell random-access memory (DCRAM), to realize major operations of ROF: threshold decomposition and polarization. Using the memory-oriented architecture, the proposed ROF processor can benefit from high flexibility, low cost and high speed. The
