Consider a computer system that has the following characteristics:
The memory bus runs at 400 MHz.
The memory bus is 8 bytes wide.
Accessing a memory address in memory requires 8 memory bus cycles.
The disk drives can each read a block every 4 milliseconds.
Disk blocks read are 8 kilobytes each.
Assume Direct Memory Access from the disk drive.
What is the highest percentage of the memory bus capacity that could be consumed by the disk’s Direct Memory Access if there are 4 disk drives in use?
Consider an operating system that uses 48-bit
virtual addresses and 16KB pages. The system
uses a hierarchical page table design to store all
the page table entries of a process, and each
page table entry is 4 bytes in size. What is the
total number of pages that are required to store
the page table entries of a process, across all
levels of the hierarchical page table?
In a microcomputer, the addresses of memory locations are binary numbers that identify each memory circuit where a byte is stored. The number of bits that make up an address depends on how many memory locations there are. Since the number of bits can be very large, the addresses are often specified in hex instead of binary.
If a microcomputer uses a 24-bit address, how many different memory locations are there?
What is the largest number that can be
How many hex digits are needed to represent the address of a memory location?
What is the hex address of the 172th memory location? (Note: The first address is always )
The computer program is stored in the lowest 3 kbyte block of memory. Give the start and end address of this
What is the BCD code of the hex address of the 172th memory location?

- In a main memory-disk virtual storage system, the page size is 1KByte and the OPTIMAL algorithm is used for page replacements. A given program has been allocated three page frames in the main memory and it makes the following 16 memory references when it starts executing (the addresses are given in decimal):500, 2000, 2500, 800, 4000, 1000, 5500, 1500, 2800, 400, 5000, 700, 2100, 3500, 900, 2400 Fill in the contents of the three page frames after each memory reference in a table and calculate the hit ratio. Hint: denote by 'a' the page consisting of locations 0 through 1023 in memory. Similarly, b: 1024-2047, c: 2048-3071, d: 3072-4095, e: 4096-5119 and f: 5120-6143.

Suppose we use two-level paging and arrange for all page tables to fit into a single page frame. How will the bits of the address be divided up? (show your work) c. Suppose we have a program with a 4GiB address space. Counting the program and all page tables, using the two-level page table scheme from the previous question, how much memory, in number of page frames, is used? (show your work)arrow_forwardUnlike a byte that is always 8 bits, word size can vary from machine to machine. Let's say we have a 16-bit system (word size is 2 bytes) and a memory unit that has 10 address lines. Because there are 10 address bits, we can have 210 unique addresses, hence 1024 addresses. If we are working with something word-addressable, that means each word has a unique address, and we canstore 1024 words. The memory size is 1 kiloword, or equivalently, 2kilobytes because each word is 2 bytes long. The address of the first word is 0, the second word is 1, the third word is 2, and the last word is 1023.Now, with 4 address lines and a word size of 4 bits, what is the address of the last word?arrow_forward
