TMC2249A
Functional Description
The TMC2249A performs the summation of products
described by the formula:
S(N+5) =A(N-ADEL) B(N-BDEL) (-1
C(N-CDEL) D(N-DDEL) (-1
CAS(N+3 FT)
where ADEL through DDEL range from 1 to 16 pipe delays.
All inputs and controls utilize pipeline delay registers to
maintain synchronicity with the data input during that clock,

except when the Cascade data input is routed directly to the
accumulator by use of the Feedthrough control. One-half
LSB rounding to 16 bits may be performed on the sum of
products while summing with the cascade input data.
The user may access either the upper or lower 16 bits of the
24-bit accumulator by swapping overlapping registers. The
output bus has an asynchronous high-impedance enable, to
simplify interfacing to complex systems.
