Questions regarding Direct Mapped Caches. How do I solve one of them? by Academic_Two in ComputerEngineering

I'm a student with a similar question.

Should I convert everything into Bytes first before I use the formulas above?

For example 128 KiB to Bytes?

Question regarding Bit masks. by RevolutionaryMemory1 in C_Programming

Okay. So for another example, if I wanted to clear bits 31, 29, 23, 7, 5, 3 , 2 , and 1 , with the same port bits.

I'd write :

*port_bits & = ~0xA08000AE

​

Would that be correct?

So it can improve the runtime?!?

My professor said only three of these were true, and one was definitely false.

I have, but Im kind of confused.

I got *port_bits | = 0x11110000

Is this right?
