SOLEON and AstroChip 7.9.2006
IMPORTANT: copy the content of SOLEON.txt into the
compiler window with control-v instead of using
the load feature of AstroChip. Otherwise the
action takes too long.
SOLEON is a graphics acceleration chip, which was
written with AstroChip. The design was done on the
level of PLAs and logical functions. This is the
lowest level above the physical level. A module offers
the operators ADDER, SUBTRACTER, MULT and DIV for
floating-point operations, which calculate the results
in one cycle. Dividing is nine times slower than adding.
SOLEON is parallel scalable, if another logic is added.
So for example 800X600 pixels may be calculated in
one cycle. This is only the potential because the chip
can only be small. The internal floating point format is
(1,23,8) (IEEE754 standard). The not-normalized numbers
are rounded to zero, which can cause small derivations for
very small numbers.
SOLEON is an OpenSource-application, which can be
tested and changed. Commercial use requires a license
from Astro Solutions. Demand is not expected because
SOLEON was not written in VHDL.
