Hi,
Can you design a 8 bit magnitude comparator with using only simple 2x1 MUX with minimum logic gates?
Can you design a 8 bit magnitude comparator with using only simple 2x1 MUX with minimum logic gates?
A parallel 8-bit magnitude comparitor requires simultaneously operating on 16 bits of data. Muxes only allow you to look at half the data at a time, so do not seem well suited.
A serial magnitude comparator, where a pair 1 of 8 bits are selected out of the two 8 bit bytes, could utilize a tree of muxes.
Why would you want to? Is this homework?I mean, I made it with 70-80 MUXes, i want to decrease the number,
It's a question from somebody, but we will decide the minimum number of 2x1 muxesWhy would you want to? Is this homework?
I finally reduced the number to the minimum I think.You should not need THAT many muxes to do the job.
You probably could make a unit that compares one bit position strating with MSB, if one bit is higher than that number wins, if they are the same you enable the next stage, repeat until you reach LSB.
