Description
The TMC2301 is a VLSI circuit which supports image
resampling, rotation, rescaling and filtering by generating
input bit plane, interpolation coefficient lookup table, and
output bit plane memory addresses along with external
multiplier-accumulator control signals. The TMC2301 can
process data fields of up to 4096 x 4096 multibit words at a
clock rate of up to 20 MHz. An Image Resampling
Sequencer (IRS) based system can nearest-neighbor resam-
ple a 512 x 512 image in 15 milliseconds, translating, zoom-
ing, rotating, or warping it, depending on the transform
parameter set loaded. A complete bilinear interpolation of
the same image can be completed in 60 milliseconds. Image
resampling speed is independent of the angle of rotation,
degree of warp, or amount of zoom specified.
A high performance, TMC2301-based system can execute
bilinear and cubic convolution algorithms that rotate images
accurately and in real time. Keystone or other perspective
correction, image plane distortion, and numerous other
second order polynomial transformations can be program-
med and executed under direct user control. Direct access to
the interpolation coefficient lookup table allows dynamic
modification of the algorithm.
Following an initialization with the transform parameters
and control bits defining the operation to be executed, the
IRS assumes control of the input and output data fields and
executes unattended. All inputs except INTER and all out-
puts are registered on the rising edge of clock. All outputs
are three-state controlled except ACC, CZERO, END, and
DONE.
Fabricated in a 1 micron CMOS process, the TMC2301
operates at clock rates of up to 20 MHz over the full
commercial (0 to 70
°
C) temperature and supply voltage
ranges. All signals are TTL compatible.
