Functional Description
General Information
The TMC2243 consists of three identical arithmetic cells,
each of which contains a 10 x 10 two's complement multi-
plier and a 23-bit adder. Each cell receives the current data
(DI) from the Data input register, multiplies it by a locally
stored Coefficient (CI
i
), and adds it to the Sum SI
received from the previous cell. The result,
(i-1)
SI
i
= DI x CI
i
+ SI
(i-1)
,
then goes to the next cell via two serial pipeline registers.
When only one pipeline register is enabled, stages (i-l) and i
are sequential. When both registers are enabled, there is a
stage with a zero coefficient between them.
The input arithmetic cell receives SI

bits with 100 000 (1/2 LSB) for internal rounding. The out-
put cell outputs 16 of the MSBs (V
through a register to the Sum-Out port. The Overflow flag is
set when the final output exceeds 16 bits and resets with the
output of the next nonoverflowing result. Sum-Out and the
Overflow Flag can be forced to high-impedance with the
Output Enable control. See Figure 1.

The two-bit Write Enable control specifies the loading of the
three coefficient registers (one per arithmetic cell) with data
appearing at the Coefficient Input port.
