TMC2246A  
Image Filter  
11 x 10 bit, 60 MHz  
Features

• 60 MHz computation rate  
• 60 MHz data and coefficient input  
• Four 11 x 10-bit multipliers  
• Fast pixel interpolation  
• Fast image manipulation

• Fractional and integer two’s complement data formats  
• Input and output data latches with user-configurable  
enables  
• One- and two-dimensional image processing  
• Selectable 16-bit rounded output  
• Internal 1/2 LSB rounding  
• Available in 120-pin CPGA, PPGA, MPGA, or MQFP  
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).
