DESCRIPTION:
The IDT7216/IDT7217 are high-speed, low-power
16 x 16-bit multipliers ideal for fast, real time digital signal
processing applications. Utilization of a modified Booths
algorithm and IDT’s high-performance, submicron CMOS
technology, has achieved speeds comparable to bipolar (20ns
max.), at 1/10 the power consumption.
The IDT7216/IDT7217 are ideal for applications requiring
high-speed multiplication such as fast Fourier transform
analysis, digital filtering, graphic display systems, speech
synthesis and recognition and in any system requirement
where multiplication speeds of a mini/microcomputer are
inadequate.
All input registers, as well as LSP and MSP output regis-
ters, use the same positive edge-triggered D-type flip-flop. In
the IDT7216, there are independent clocks (CLKX, CLKY,
CLKM, CLKL) associated with each of these registers. The
IDT7217 has only a single clock input (CLK) and three register
enables.
ENX and ENY control the two input registers, while
ENP controls the entire product.
The IDT7216/IDT7217 offer additional flexibility with the FA
control and
MSPSEL functions. The FA control formats the
output for two’s complement by shifting the MSP up one bit
and then repeating the sign bit in the MSB of the LSP. The
