- note = { In order to reduce computational complexity of extracting
ridges and ravines, two approaches called explicit
arithmetic formulae (EAF) and explicit arithmetic
formulae with local memory (EAFWLM) are proposed and
compared to the approach in which the derivative formulae
are used. An even strip parallel algorithm with different
approaches of reducing complexity of extraction procedure
were implemented on a GCel-1/64 transputer based parallel
machine. The results show that the approach of using
EAFWLM can greatly reduce the computational complexity
of the extraction procedure and significantly ease
load balance problem. The even strip parallel algorithm,
in conjunction with the EAFWLM approach as an optimized
parallel algorithm has shown the much better performance
comparing with the other two approaches. },

- note = " The VC-1 is a parallel graphics machine for polygon
rendering based on image composition. This paper describes
the architecture of the VC-1 along with a parallel
polygon rendering algorithm for it. The structure
of the VC-1 is a loosely-coupled array of 16 general-
purpose processors, each of which is equipped with
a local frame buffer. The contents of the local frame
buffers are virtualized with a demand-paging technique,
by which the image memory capacity for each local
frame buffer is reduced to one eighth of the full-screen
capacity. Polygons are rendered in either pixel parallel
or polygon parallel depending on the on-screen area
of each polygon. The real performance of the VC-1
as well as estimated performance for systems with
up to 256 processors is shown. ",
