संकल्पना:

बहुपथी:

  • बहुपथी म्हणजे अनेक ते एक डेटा निवडक.
  • सिलेक्ट रेषेवरील बिट्सच्या आधारावर बहुपथी त्याच्या इनपुटवर उपलब्ध असलेल्या अनेक डेटापैकी एक निवडतो.
  • आठ इनपुट निवडण्यासाठी, तीन डेटा सिलेक्ट रेषा आहेत ज्या वापरल्या पाहिजेत. मल्टीप्लेक्सरला डेटा सिलेक्ट रेषेची आवश्यकता असते. आमच्याकडे आठ इनपुटसाठी तीन डेटा सिलेक्ट रेषा आहेत आणि ते 8:1 बहुपथी आहे.

उदाहरण:

16 x 1 बहुपथी 8 इनपुटपैकी एक निवडतो आणि आउटपुटमध्ये सादर करतो, म्हणजे

2m  = 16
m = log2 16 = log2 (24)
m = 4log2 2
m = 4

तर, डेटा निवडलेल्या रेषांची संख्या 4 आहे.
