An image resizing IC for multiple window display
Ching-Mei Huang, Chein-Wei Jen · 2002
An image resizing IC which can perform real-time multiple window size adjustment is designed. In this resizer, the multiplierless, modulized CIC (Cascaded Integrator-Comb) filters are chosen to execute band-with filtering. Filter stages can be allocated to image resizing processes for different size windows according to our hardware utilization rule. An overlap-save skill is applied on account of delay line memory reduction. Our design is further implemented into IC using CCL's 0.8 um cells library and is scheduled to serve the resizing process of four 320/spl times/200 image resources 30 frames per second.
