DESCRIPTION:
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.
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.
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
