SoC 101 - Lecture 6d: Virtual Memory

[@ahmadirtisam]

Do all programs and I/O devices have the same virtual address space and different page table entries?

[@AdiTeman]

No, at least if I understood your question. Each I/O device gets it's own physical range of addresses. Each process (i.e., instance of a program) gets its own page table. But usually, as I cover in the next lecture, the actual operations to and from the I/Os are done using system calls to the operating system. So the operating system handles these.

Sir, I need slides of this lecture, unable to access your site.

Hi, The link isn't available, since the university has blocked access for IPs originating outside of Israel for security purposes. I have uploaded my lecture slide to a sharepoint drive in the meantime, so you can access them here: biu365-my.sharepoint.com/:f:/g/personal/temanad_biu_ac_il/EuORrTC7arlEn3S9M-0q2fEBd5DnUUiMIJ6DFd6cCPl4zw?e=aUktHb
