DEVICES INCORPORATED
Coordinate Transformer
DESCRIPTION
The
L2330
is a coordinate transformer
that converts bidirectionally between
Rectangular and Polar coordinates.
When in Rectangular-to-Polar mode,
the L2330 is able to retrieve phase and
magnitude information or backward
map from a rectangular raster display
to a radial data set.
When in Polar-to-Rectangular mode,
the L2330 is able to execute direct
digital waveform synthesis and
modulation. Real-time image-space
conversions are achieved from radi-
ally-generated images, such as RADAR,
SONAR, and ultrasound to raster
display formats.
Functional Description
The L2330 converts bidirectionally
between Rectangular (Cartesian) and
Polar (Phase and Magnitude) coordi-
nates. The user selects the numeric
format. A valid transformed result is
seen at the output after 22 clock cycles
and will continue upon every clock
cycle thereafter.
When in Rectangular-to-Polar mode,
the user inputs a 16-bit Rectangular
coordinate and the output generates a
Polar transformation with 16-bit
magnitude and 16-bit phase. The user
may select the data format to be either
two’s complement or sign-and-
magnitude Cartesian data format.
Polar Magnitude data is always in
magnitude format only. Polar Phase
Angle data is modulo 2π so it may be
regarded as either unsigned or two’s
complement format.
When in Polar-to-Rectangular mode,
the user inputs 16-bit Polar Magnitude
and 32-bit Phase data and the output
generates a 16-bit Rectangular coordi-
nate. The use may select the data
format to be either two’s complement
or sign-and-magnitude Cartesian data
format.
