in a paged-segmented system we have the virtual address of 32 bits and 12 bits for the offset,11 bits for segment and 9 bits for page number.the how can we calculate the page size ,maximum segment size and maximum number of segment size?
- 12 bits are reserved for offset, so the page size is 2^12 = 4KB
- 9 bits are reserved for page number, so each segment can contain 2^9 = 512 pages
- Each segment can grow up to size of (# of pages) * (pages size), so maximum segment size is 512 * 4K = 2M
