HMU16, HMU17
D a ta Sheet N o v em b e r 1999 F i l e Number 2803.4
16 x 16-Bit CMOS Parallel Multipliers
The HMU16 and HMU17 are high speed, low power CMOS 16-bit x 16-bit multipliers ideal for fast, real time digital signal processing applications. The X and Y operands along with their mode controls (TCX and TCY) have 17-bit input registers. The mode controls independently specify the operands as either two's complement or unsigned magnitude format, thereby allowing mixed mode multiplication operations. Two 16-bit output registers are provided to hold the most and least significant halves of the result (MSP and LSP). For asynchronous output, these registers may be made transparent through the use of the Feedthrough Control (FT). Additional inputs are provided for format adjustment and rounding. The Format Adjust control (FA) allows the user to select either a left shifted 31-bit product or a full 32-bit product, whereas the round control (RND) provides the capability of rounding the most significant portion of the result. The HMU16 has independent clocks (CLKX, CLKY, CLKL, CLKM) associated with each of these registers to maximize throughput and simplify bus interfacing. The HMU17 has only a single clock input (CLK), but makes use of three register enables (ENX, ENY and ENP). The ENX and ENY inputs control the X and Y Input Registers, while ENP controls both the MSP and LSP Output Registers. This configuration facilitates the use of the HMU17 for microprogrammed systems. The two halves of the product may be routed to a single 16-bit three-state output port via a multiplexer, and in addition, the LSP is connected to the Y-input port through a separate three-state buffer.
