HMU17/883

16 x 16-Bit CMOS Parallel Multiplier

October 1997

Features

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 for-

mat, thereby allowing mixed mode multiplication operations.

• This Circuit is Processed in Accordance to MIL-STD-

883 and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

• 16 x 16-Bit Parallel Multiplier with Full 32-Bit Product

• High-Speed (45ns) Clocked Multiply Time

• Low Power CMOS Operation

Additional inputs are provided to accommodate format adjust-

ment and rounding of the 32-bit product. The Format Adjust con-

trol 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 signiﬁ-

cant bit of the LSP.

• HMU17/883 is Compatible with the AM29517, LMU17,

IDT7217, and the CY7C517

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 three-

state output port via the output multiplexer control, and in addi-

tion, the LSP is connected to the Y-input port through a separate

three-state buffer.

• Supports Two’s Complement, Unsigned Magnitude

and Mixed Mode Multiplication

• TTL Compatible Inputs/Outputs

- Three-State Output

Ordering Information

The HMU17/883 utilizes a single clock signal (CLK) along with

three register enables (ENX, ENY, and ENP) to latch the input

operands and the output product registers. The ENX and ENY

inputs enable the X and Y input registers, while ENP enables both

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.
