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.
