General Description
The IP00C721 is a low-cost device for real-time image resizing and frame rate conversion up to
Wide-XGA resolution output. It features a 4x4 pixel interpolation core, with higher sub-pixel
resolution than previous devices. The IP00C721 has 2 image input ports: 1) digital RGB 24 bits
up to 108 MHz, and 2) digital YUV up to 80 MHz. The output image port can be either 24 bits
or 30 bits with a maximum speed of 80 mpixels/sec, and can be driven by an internal or external
pixel clock. Lower bit resolutions are also supported for 18-bit display devices. The input and
output image ports are completely independent to allow simultaneous image scaling and frame
rate conversion. The IP00C721 has an embedded image memory controller for direct interface to
an external SDRAM device. The IP00C721 is ideally suited for applications such as projectors and
low-cost display systems.
