INTRODUCTION

The ZR36067

The ZR36067 is a PCI adapter intended for multimedia applications on PCI systems. It supports high rate code (compressed data stream) transfer between the system memory and JPEG or MPEG processors. Simultaneously to the code transfer, the ZR36067 captures digital video, such as decompressed MJPEG (Motion JPEG), MPEG, or the output of a video decoder, and creates a scaled video window in the graphics display memory.

FEATURES

■ Supersedes the Zoran ZR36057.

■ Glueless interface to PCI bus (PCI spec. 2.1 compliant).

■ Minimum interface to JPEG decoders (ZR36060, ZR36050+ZR36016), MPEG1 and DVD decoders (ZR36110, ZR36700), video decoders and video encoders.

■ Bidirectional DMA transfer of compressed data up to 11M bytes/sec.

■ DMA transfer of video and mask information.

■ Support for fast still image compression and decompression.

■ Smooth image down-scaler (up to 5-tap horizontal filter).

■ On-chip pixel accurate masking.

■ YUV-to-RGB converter with quantization noise reduction by error diffusion.

■ Video output: 15- and 16-bit RGB pixel formats, as well as 24-bit (packed and unpacked), and YUV 4:2:2.

■ Hardware support for non-contiguous JPEG code buffers.

■ Graceful recovery from extreme bus latencies both on video and code transfers.

■ Choice of emulated interlaced video display, or single field display, to eliminate motion artifacts.

■ Hardware support for simple, cost effective frame grabbing.

■ I2C bus master port.

■ Plug & Play support.

■ 208-pin PQFP package.

■ Support for Subsystem ID and Subsystem Vendor ID.

APPLICATIONS

■ High quality video and audio capture/playback and editing boards for PCI systems.

■ Multimedia/Graphics subsystems using a secondary PCI bus.

■ PCI motherboards with multimedia capability.

■ JPEG/MPEG1 solutions for PowerPC and Macintosh PCI systems.
