16 x 16-Bit CMOS Parallel Multiplier
Description
The HMU17/883 is a high speed, low power CMOS 16 x 16-bit
parallel multiplier ideal for fast, real time digital signal processing
applications. The 16-bit X and Y operands may be independently
specified as either two’s complement or unsigned magnitude format, thereby allowing mixed mode multiplication operations.
Additional inputs are provided to accommodate format adjustment and rounding of the 32-bit product. The Format Adjust control allows the user the option of selecting a 31-bit product with
the sign bit replicated LSP. The Round control is provided to
accommodate rounding of the most significant portion of the
result. This is accomplished by adding one to the most significant bit of the LSP.
Two 16-bit output registers (MSP and LSP) are provided to hold
the most and least significant portions of the result, respectively.
These registers may be made transparent for asynchronous
operation through the use of the Feedthrough Control (FT). The
two halves of the product may be routed to a single 16-bit threestate output port via the output multiplexer control, and in addition, the LSP is connected to the Y-input port through a separate
three-state buffer.
The HMU17/883 utilizes a single clock signal (CLK) along with
three register enables (
operands and the output product registers. The
inputs enable the X and Y input registers, while
the LSP and MSP output registers. This configuration facilitates
the use of the HMU17/883 for micro-programmed systems.
All outputs of the HMU17/883 also offer three-state control for
multiplexing onto multiuse system busses.
