A multiplierless reconfigurable resizer for multi-window image display

Abstract

This paper presents a real-time resizing IC that can dynamically reconfigure the multiplierless polyphase CIC (cascaded-integer-comb) filter modules to meet even noninteger resizing ratio. The hardware cost is greatly reduced by using overlap-save based block input and concurrent register reset scheme. The simulated results show that this chip can process four 320x200 30 frames/sec at 55 MHz clock.
