INTRODUCTION
The ZR36060 is an integrated JPEG codec targeted to video capture and editing applications in desktop and laptop computers. Figure 1 shows an example of a typical application, a video editing subsystem for PCI bus computers.
   
FEATURES
■ Single-chip JPEG processor which integrates all the modules needed for JPEG encoding and decoding:
    - Raster-to-block and block-to-raster converter
    - Strip buffer
    - JPEG codec
■ Motion video compression and expansion capability:
    - Up to 25 frames/sec, square pixel and CCIR PAL
    - Up to 30 frames/sec, square pixel and CCIR NTSC
■ Three modes of Bit Rate Control (BRC):
    - Auto Two Pass: for still image compression, produces tightly controlled compressed data file size
    - Single pass: for motion video compression, keeps the file size approximately fixed
    - No BRC: uses fixed quantization tables
■ Glueless interface to common video decoders (e.g., Philips, Brooktree, Samsung, ITT, Harris)
■ Glueless interface to the ZR36057, I32 and other common multimedia controllers.
■ Supports 8 and 16-bit YUV video interfaces
■ Supports master and slave modes of video synchronization
■ Interfaces to a variety of host controllers, ranging from the dedicated high-performance ZR36057 PCI controller to generic low-cost microcontrollers
■ Flexible compressed data interface:
    - 8-bit master mode, supporting transfer of up to 30 Mbytes/sec
    - 16-bit slave mode, supporting transfer of up to 16.7 Mbytes/sec
    - 8-bit slave mode, supporting transfer of up to 8.3 Mbytes/sec
■ On-chip video processing, including:
    - Mixing of two video sources
    - Horizontal (1:2 and 1:4) and vertical (1:2) up and down scaling
    - Cropping in compression and programmable background color in decompression
■ 3.3V power supply with 5V-tolerant I/O
■ Low power consumption:
    - 850 mW at 30 MHz operating frequency
    - Power down mode for power saving
■ 100-pin PQFP package
   
APPLICATIONS
■ Desktop video editing subsystems
■ PCMCIA video capture cards
■ Digital still cameras
■ Digital video recording
■ JPEG-based video conferencing systems
