I would like to know about Graphics or Immage or Parrern Recognition
processors which are develope now in universies or VLSI companies;
We are plainig systems in these areas and would like to coperate.

It consists of a 6 by 12 array of bit-serial processors on a single chip. Each processor has 128 bits of memory (organized as 128 words of 1 bit each), a bit-serial ALU that can sometimes do two or three operations in parallel (depending on which resources the operations use), and communications channels to the four adjacent processors on a square grid (or off chip if at the edge of the array). The chips can be stacked in X and/or Y to get larger arrays. There is a development system available on IBM PC. The chip (or array for chips) is an SIMD machine, since all processors are attached to a global address and instruction bus. For image procesing you would typically shift in the image from one edge of the array, do the computation, and shift out the result. All in all, an interesting architecture. But why 6 X 12? Why not 8 X 8? I have no connection with NCR except that I read their literature and work for one of their competitors. -- Howard A. Landman ...!intelca!mipos3!cpocd2!howard

My M.Sc. Thesis topic - implementation of Least Square Estimate algorithm in VLSI. It is based on the Modified Graham Shmidt algorithm by Dr. Fuyun Lean and John Proakis. It is conducted at Northeastern Un. in Boston. This type of algorithm is very attractive in echo canslation and adaptive filtering. It might be suitable in areas like Pattern recognition. I would like to know about a VLSI library that has cells like- integer multipliers, division arrays and etc. Thank you --- Rafael Diaz diaz@m2c.org harvard!halleys!diaz@harvard.harvard.edu -- --- Rafael Diaz diaz@m2c.org harvard!halleys!diaz@harvard.harvard.edu
