Abstract

The invention discloses a K-value and ten-value signal controlled data distributor and data selector. The K-value data distributor is composed of K CMOS transmission gates, K CMOS NOT gates, K logic value discrimination gates and K NMOS tubes. The K NMOS tubes of the K-value data distributor are deleted, and then input is changed into output and output is changed into input so that the K-value data selector is obtained. The K-value data selector and the distributor are important devices for changing a K-value data transmission channel. In order to popularize a chaotic encryption method and an encryption circuit from 2-value information to K-value information, the K-value data selector and the distributor can be used so that a K-value shift data selector is realized, K-value multiplication and division operation is substituted by addition and subtraction operation, and thus a no-multiplication-and-division chaotic encryption circuit of K-value information is realized. The data distributor and the data selector are applied to the technical fields of VLSI like FPGA, CPLD, semi-custom or full-custom ASIC and memories and other digital IC.

Description

(1) Technical field

[0001] The invention belongs to the field of digital integrated circuits, in particular to a data distributor and a data selector controlled by K value and ten value signals. (2) Background technology

[0002] With the rapid development of MOS integrated circuit technology, the scale of integration is getting larger and higher, and VLSI (Very Large Scale Integration) has some shortcomings: ① First, on the VLSI substrate, the wiring takes up more than 70℅ of silicon Chip area; in programmable logic devices, a large number of programmable internal wiring is also required to connect each logic function block or input / output to complete a specific function circuit, and wiring accounts for a large cost of materials. Reducing the proportion of wiring costs becomes a very important issue. ② From the perspective of information transmission, the use of multi-valued signals can reduce the number of connections; for each connection to transmit digital information, ...
