Functional Description

The TMC2246A Image Filter is a flexible multiplier-summer

array which computes the accumulated sum of four 11x10

bit products, allowing word growth up to 25 bits.

The inputs are user-configurable, allowing latching of either

the 10- or 11-bit input data. The data format is user-selectable

between integer or fractional two’s complement arithmetic.

Total latency from input registers to output data port is 5

clocks.

The output data path is 16 bits wide, providing the lower 16

bits of the accumulator when in integer format or the upper

16 bits of the 25-bit accumulator path when fractional two’s

complement notation is selected. One-time rounding to 16

bits is performed automatically when accumulating frac-

tional data, but is disabled when operating in integer format

to maintain the integrity of the least-significant bits.
