FEATURES
DESCRIPTION
The LF2250 is a high-speed matrix
multiplier consisting of an array of
nine 12 x 10-bit multipliers. Internal
summing adders are also included to
provide the configurations needed to
implement matrix multiplications,
cascadable FIR filters, and pixel
convolvers.
The 3 x 3 matrix multiplier (triple dot
product) configuration of the LF2250
allows users to easily perform three-
dimensional perspective translations or
video format conversions at real-time
video rates. By using the LF2250 in
this configuration, conversions can be
made from the RGB (color component)
format to the YIQ (quadrature encoded
chrominance) or YUV (color differ-
ence) formats and vice versa (YIQ or
YUV to RGB).
In addition to color space conversions,
the LF2250 offers a range of selectable
configurations designed for filtering
applications. When configured as a
9-tap FIR filter, the LF2250 automatically
selects the necessary internal bus
structure and inserts the appropriate
data path delay elements. In addition,
a 16-bit cascade input port allows for
the creation of larger filters without a
reduction in throughput.
Real-time video image filtering using
the convolver modes of the LF2250 can
provide edge detection, texture
enhancement, and detail smoothing.
Both pixel convolver configurations,
3 x 3 and 4 x 2, deliver high-speed data
manipulation in a single chip solution.
By using the 16-bit cascade input port
to cascade two devices, cubic convolu-
tions (4 x 4-pixel) can be easily accom-
modated with no decrease in through-
put rates.
All inputs and outputs, as well as all
control lines, are registered on the
rising edge of clock. The LF2250
operates at clock rates up to 50 MHz
over the full commercial temperature
and supply voltage ranges.
