FEATURES Complete single-chip JPEG 2000 compression and decompression solution for video and still images Identical in pinout and footprint to the ADV202 and supports all the functionality of the ADV202 Power reduction of at least 30% compared with ADV202 JTAG/boundary scan support Patented SURF® (spatial ultraefficient recursive filtering) technology enables low power, low cost wavelet-based compression Supports both 9/7 and 5/3 wavelet transforms with up to 6 levels of transform Video interface directly supporting ITU-R BT.656, SMPTE 125M PAL/NTSC, SMPTE 274M, SMPTE 293M (525p), and ITU-R BT.1358 (625p), or any video format with a maximum input rate of 65 MSPS for irreversible mode or 40 MSPS for reversible mode Programmable tile/image size with widths up to 4096 pixels in single-component mode; maximum tile/image height: 4096 pixels 2 or more ADV212s can be combined to support full-frame SMPTE 274M HDTV (1080i) or SMPTE 296M (720p) Flexible, asynchronous SRAM-style host interface allows glue- less connection to most 16-/32-bit microcontrollers and ASICs 2.5 V or 3.3 V input/output and 1.5 V core supply 12 mm × 12 mm, 121-ball CSPBGA with a speed grade of 115 MHz, or 13 mm × 13 mm, 144-ball CSPBGA with a speed grade of 150 MHz APPLICATIONS Networked video and image distribution systems Wireless video and image distribution Image archival/retrieval Digital CCTV and surveillance systems Digital cinema systems Professional video editing and recording Digital still cameras Digital camcorders GENERAL DESCRIPTION The ADV212 is a single-chip JPEG 2000 codec targeted for video and high bandwidth image compression applications that can benefit from the enhanced quality and features provided by the JPEG 2000 (J2K)—ISO/IEC15444-1 image compression standard. The part implements the computationally intensive operations of the JPEG 2000 image compression standard and provides fully compliant code-stream generation for most applications. The dedicated video port of the ADV212 provides glueless con- nection to common digital video standards such as ITU-R BT.656, SMPTE 125M, SMPTE 293M (525p), ITU-R BT.1358 (625p), SMPTE 274M (1080i), or SMPTE 296M (720p). A variety of other high speed, synchronous pixel and video formats can also be supported by using the programmable framing and validation signals. The ADV212 is an upgrade version of the ADV202 that is identical in pinout and footprint. It supports all the functionality of the ADV202 and has the following additional options: • JTAG/boundary scan support • Power reduction of at least 30% compared with the ADV202 FUNCTIONAL BLOCK DIAGRAM PIXEL I/F EXTERNAL DMA CTRL WAVELET ENGINE INTERNAL BUS AND DMA ENGINE PIXEL I/F EC1 EC2 EC3 EMBEDDED RISC PROCESSOR SYSTEM RAM ROM ADV212 CODE FIFO PIXEL FIFO ATTR FIFO HOST I/F Figure 1. |
