Although I don't know of a single chip solution, there are a couple 
of useful devices you may like to take a look at.
These are the Inmos IMSA121, and the SGS-Thomson STV3208.
Both of these perform the Discrete Cosine Transform in 8x8 blocks,
and for information on this I refer you to the paper
"Image compression using a discrete cosine image processor"
   by D J Bailey, and N Birch of Inmos

as well as the "Image Processing DataBook" by SGS-Thomson.

If you are unfamiliar with the DCT (Discrete Cosine Transform), I refer 
you to Transactions of the IEE, for papers on the subject.

If you need more information on the two devices I have mentioned,
then try

If you need any more help I shall try to give you some pointers, but 
I must say that I am just learning at the moment myself

Look on page 16 of the Nov. 23, 1992 EE Times. I believe that there was a
short News Brief on such a chip from IBM. I can't tell you for sure,
because I cut out the article and gave it to a colleague who was also
looking for such a beast. If he still has the article, I will post again.
