发明名称 IMAGE SCALER
摘要 PURPOSE: An image scaler is provided to minimize the memory size by increasing a clock frequency of a memory. CONSTITUTION: A horizontal scaler scales image pixels to a horizontal direction. A vertical scaler(200) scales the horizontal direction scaled pixels to a vertical direction. A single memory(300) comprises a line memory, an FIFO memory, and a memory wrapper. The single memory changes the line memory and the address information write of the FIFO memory enable signal into a memory control signal. Through a read/write data muxing operation and a buffering operation, the memory wrapper processes the handshaking operation between the memory clock and the scaling clock.
