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.
