Description

The TMC2246A is a video-speed convolutional array com-

posed of four 11 x 10 bit registered multipliers followed by a

summer and an accumulator. All eight multiplier inputs are

accessible to the user and may be updated every clock cycle

with integer or fractional two’s complement data. A pipe-

lined architecture, fully registered input and output ports,

and asynchronous three-state output enable control simplify

the design of complex systems.

The data or coefﬁcient inputs to the multipliers may be held

over multiple clock cycles, providing storage for mixing and

ﬁltering coefﬁcients. The 25-bit internal accumulator path

allows two bits of cumulative word growth and may be inter-

nally rounded to 16 bits. Output data are updated every clock

cycle, or may be held under user control. All data inputs, out-

puts, and controls are TTL compatible and (except for the

three-state output enable) are registered on the rising edge of

CLK.

The TMC2246A is uniquely suited to performing pixel inter-

polation in image manipulation and ﬁltering applications. As

a companion to the Fairchild Semiconductor TMC2301 and

TMC2302 Image Manipulation Sequencers, the TMC2246A

can execute a bilinear interpolation of an image (4-pixel ker-

nels) at real-time video rates. Larger kernels or other, more

complex, functions can be realized with no loss in performance

by utilizing multiple devices.

With unrestricted access to all data and coefﬁcient input

ports, the TMC2246A offers considerable ﬂexibility in appli-

cations performing digital ﬁltering, adaptive FIR ﬁlters, mix-

ers, and other similar systems requiring high-speed

processing.

Fabricated in a submicron CMOS process, the TMC2246A

operates at a guaranteed clock rate of 60 MHz over the full

temperature and supply voltage ranges. It is pin- and func-

tion-compatible with Fairchild’s TMC2246, while providing

higher speed operation and lower power dissipation. It is

available in a 120 pin Plastic Pin Grid Array (PPGA), 120

pin Ceramic Pin Grid Array (CPGA), 120 lead MQFP to

PPGA (MPGA), and a 120 lead Metric Quad FlatPack

(MQFP).
