Description
The TMC3211 is a fast monolithic two’s complement integer
divider which can divide a 32-bit dividend by a 16-bit divisor
to produce a 32-bit quotient, with a maximum pipelined
throughput of 20 MOPS (Million Operations Per Second).
Data is input on separate busses, and quotients are available
on a 32-bit output bus with synchronous three-state enable.
All data inputs and outputs are registered and TTL compati-
ble. All input and output signal timing is referenced to the
rising edge of Clock.
The TMC3211 has a single system clock and separate load
enable controls for the dividend and divisor registers. This
allows the device to be used in applications requiring divi-
sion by a constant. Underflow automatically produces the
expected zero quotient, and dividing by zero sets a divide-
by-zero output flag.
The internal architecture of the TMC3211 allows all 32-bit
two’s complement integer dividends and nonzero 16-bit
two’s complement integer divisors, without prenormaliza-
tion. The output quotient format is 32-bit integer.
The TMC3211 makes a full-precision, full-speed divide
function available to designers of workstations, image
processors, and radar systems who need to perform
perspective extractions, matrix operations, range scaling, and
other complex functions.
