What is TLB for? Why TLB? Given the following number, what is theeffective memory access time?
vodomira [7]

Answer:

A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding  the frame number and the other for the address specified by frame number.

<u>Formula for finding effective memory access time-</u>

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

Given in question,

Hit ratio = 0.90

Memory Access Time = 150ns

TLB access time= 5ns

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

                            =(5+150) * 0.90 + (5+2*150)*(1-0.90)

                             =155 * 0.90 + (305*0.1)

                             =139.5 + 30.5

                             = 170ns

Which button could Pamela press in the Microsoft Word spell checker to make the word “colour” instantly change to “color” whenev
dmitriy555 [2]
One step is to right click on the word to add it to her personal dictionary. or, <span><span>Press F7. Word starts the spelling and grammar checking utility. </span><span>Make corrections, as appropriate, when prompted.
</span></span>

However, one can create a macro that would do the conversions :

1) Identify a list of words whose spelling you want to convert.2) Turn on the macro recorder. 3) Use the Replace feature to replace the spellings.4) Turn off the macro recorder.

The macro will do a conversion from one to the other. Later, as we have more words that need to be automatically replaced, we can just edit the macro and add those words.
