ZR36057
ENHANCED PCI BUS MULTIMEDIA CONTROLLER
FEATURES
T Glueless interface to PCI bus (PCI spec. 2.1 compliant).
T Minimum interface to JPEG decoders (e.g. ZR36050 &
ZR36016), MPEG1 decoders (e.g., ZR36110), video digitiz-
ers (e.g., SAA7110, SAA7111) and video encoders (e.g.,
SAA7188, MD207).
T Bi-directional DMA transfer of compressed data up to 11M
bytes/sec.
T DMA transfer of video and overlay information.
T Support for fast still image compression and decompression.
T Smooth image down-scaler (up to 5-tap horizontal filter).
T On-chip pixel accurate masking.
T YUV-to-RGB converter with quantization noise reduction by
error diffusion.
T Video output: 15- and 16-bit RGB pixel formats, as well as
24-bit (packed and unpacked), and YUV 4:2:2.
T Hardware support for non-contiguous JPEG code buffers.
T Graceful recovery from extreme bus latencies both on video
and code transfers.
T Choice of emulated interlaced video display, or single field
display, to eliminate motion artifacts.
T Hardware support for simple, cost effective frame grabbing.
T I2C bus master port.
T Plug & Play support.
T 208-pin PQFP package.
T Accompanying software includes Video For Windows (VFW)
drivers for Windows 3.1 and Windows 95.
APPLICATIONS
T High quality video and audio capture/playback and editing
boards for PCI systems.
T Multimedia/Graphics subsystems using a secondary PCI
bus.
T PCI motherboards with multimedia capability.
T JPEG/MPEG1 solutions for PowerPC and Macintosh PCI
systems.

Enhanced PCI Bus Multimedia Controller
1.2.5 Notations and Conventions
wEwxtwer.DnaaltasiSghneaelst:4U.com Capital letters (e.g., IDSEL)
Active-low mark [1]:
Overbar (e.g., DEVSEL)
Internal function units: capital (non-bold) letters (e.g., VFE)
Buses:
XXmsb_index..lsb_index (e.g., AD31..0)
Register fields:
XXmsb_index:lsb_index (e.g., Mode27:16)
Register types:
R - read only
RC - read-clear. Writing ‘1’ clears the register bit.
RS - read-set. Writing ‘1’ sets the register bit to ‘1’.
RW - read-write (contents of write can be read back)
W - write only (contents of read are meaningless)
Numbers:
Unmarked numbers are decimal (e.g., 365, 23.19). Hexadecimal numbers are marked with a ‘0x’ prefix (e.g., 0xB000,
0x3). Binary numbers are marked with a ‘b’ suffix (e.g., 010b, 0000110100011b).
1. In this document, an overbar is used to denote active low signals. In other documents referenced herein, such as the PCI specifications, the # suffix notation is often
used instead. The two forms of notation are interchangeable. Thus, for example, DEVSEL is equivalent to DEVSEL#.
