Attached is a list of sources of JPEG-related hardware, reposted with the
author's permission.  The list is probably a little dated already, but it is
a good starting point for seeking JPEG chips.  The same companies would be
likely suspects for MPEG chips...

Subject: Re: Re: Inquiry on JPEG hardware
From:    warnergt@aloft.att.com (George T. Warner)

Tom:
There seems to be a mix-up on your list of JPEG hardware.  AT&T is listed as
providing
applications for Motorola hardware... not very likely!


Here is what the list said:

The following is excerpted from:

VIDEO COMPRESSION OPTIONS, IEEE CICC 6-May-92

John J. Bloomer, jbloomer@crd.ge.com, Fathy F. Yassa, Aiman A. Abdel-Malek

General Electric Corporate R&D, KWC317 Signals and Systems Laboratory
PO Box 8, Schenectady NY, 12301


Pipelined Processors, Building Blocks (Chip Sets)

AT&T - applications for the DSP56002 (fixed-point 40MHz version of the 56001)
	- 4Mb/s with ISDN and FDDI support
	- augments the DSP3210 
	- Multimedia Development Environment compliant



The DSP56000 series are manufactured by Motorola.  AT&T offers no applications
for these devices.

AT&T offers a JPEG coder which runs on its DSP3210 under the VCOS operating
system.  The JPEG coder provides complete baseline support.  The JPEG decoder
supports interleaved and non-interleaved data, restart markers, DNL, any valid
quantization and entropy tables and combination thereof as defined in the JPEG
specification, and up to 255 color planes per frame.  Support is also provided
for subsampling and popular forms of color space conversion.  The coder color
space conversion coefficients default to YCbCr values but can overridden by
the application for virtually any color space.  YCbCrK conversion for CMYK
images is supported.  All valid combinations of sampling are directly
supported by the decoder including those requiring "fractional
desubsampling" (non-integer desubsampling).

The AT&T JPEG coder is written as a DSP module which executes under the AT&T
VCOS* Operating System on the DSP3210.  VCOS is a real-time, multitasking,
multiprocessing operating system.  The DSP3210 is a 32-bit floating point
digital signal processor designed to be easily and inexpensively incorporated
as a bus-master in microprocessor based designs.  As such, it eliminates the
need for expensive static RAM and inefficient data transfers between host and
DSP subsystems.  The JPEG coder is not an "application" in itself, althought
sample application source code is provided to developers.  The coder could be
considered a "JPEG engine" which can be utilized by any number of host
applications to perform JPEG compression/decompression through a standard
interface.  Since it executes on a multitasking operating system, the JPEG
coder can be used to simultaneously compress/decompress multiple images
and/or be used in conjunction with other DSP modules to preprocess or
postprocess the image data.  For example, using the DSP3210's bus-master
architecture, a module could be created to write the decoded image data
directly to memory mapped video hardware with no host intervention required.

Other modules available for the DSP3210 include audio coders (such as MPEG, SBC,
CDXA, and G.722), modem/fax data pumps (V.32bis, V.22bis, and V.29), DTMF, call
progress detection, sample rate conversion, and more.


Just wanted to clear that up.

AVP1000 is from AT&T Microelectronics.  The AT&T chip set handles MPEG-1,
H.261, and JPEG.  1400D has on board color space convertor.  Limited to
4Mb/s coded rate.  The DSP does the MUSICAM decoding (up to layer II, I think)

Limited to 2MB/sec (15Mb/s) coded rate.  35MHz PGA version available.  2:1
horizontal filter, on board programmable color space convertor.  Allows
on pair of quantization tables to be loaded while other pair is used to
code or decode data stream.  Needs maintanence by host.

Cancelled.  Had a microcontroller too, could operate in stand-alone fashion.
Real nice had it gone through.   Published in CICC 91, not CICC 92.

JVC mode is not MPEG-II compliant (there isn't an MPEG2 standard yet)
but is an extension of MPEG1 at a higher rate plus interlace video
handling.

CL450 - Announced June 1992.  Scaled down version of CL950, with 3Mb/sec
limit.  Does not code or decode JPEG, only MPEG-I decoding.

Phillips has exclusively contracted the CL450 for use in motion video
expansion slot on CD-I players.

Now, what about the list that details the purported bugs? :-)
