Question

A system is using segmentation to map physical memory. Current segment table is as follows. Some of the entries are stored in associative registers as given in second table. Assume that the register access time is 10 nanoseconds and memory access time is (10 x 7) nanoseconds;

 

Find the physical memory address for each of the following logical memory addresses given by <Segment no, offset>

  • Calculate effective memory access time for each
  • (a) <0,3700>

(b) <2,3780>

(c) <1,200>

Segment Table Segment no base limit 10000 1000 1 12000 2000 2 25000 4000 15000 8000 4 38000 4000
