Abstract :
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 320×200 image resources 30 frames per second
